This is a compilation of all my previous threads ive finally decided to throw back up, minus the pictures. i dont feal we need pictures to discuss things that much.


First lets start with the duratec focus information:

ok... this is to help everyone!


years the duratecs are in focus'


2.3 was released largely in 03... it was put into the 03 and 04 zx3's for the green states. yes the 03 and 04 are old bodystyles.

in 05 the Focus ZX4 ST was released and it gained the 2.3L with a few more ponies

in 05 the zx3, ZXw, ZX5, and the lower end ZX4's got the 2.0 duratec no matter manual or automatic tranny.


----

Ok onto modifications:

the difference between the 2.0 and the 2.3 are small in the fact alot of the parts that can be bought and installed on the 2.0
can in fact be bought and installed on the 2.3 and vise-versa.

HEADER (notice how i DID not put a S at the end. its a 4cylinder people, it has only 1, uno. singular, mono):

F2 V3.0 Step Header. has a stepped design, it has 1-5/8" primaries and 1-3/4" secondaries and a 2.5" collector. to contain some of the back pressure.
Cosworth Header
Focussport header (stock or aftermarket flex can be used, Focussport is in the process of making their flexpipe)

Intake:

you have a few more options here.

Steeda:

SRI i.e. short ram intake, comes with an alluminum heat shield that sits right behind the d/s headlight.

Focussport.com CAI:

Alluminum Cold air intake, uses stock MAF tube, but comes with a very nice ITG air filter.

Cosworth CAI:

3 piece design replaces all 3 pieces in the intake, BUT! it bottle necks at the MAF, because the maf is programmed from ford to work
inside a certain diameter tube.

F2focus shortram/cai:

This is kinda like the stealth intake, not a true short ram, but not a true CAI either.

Stealth mod:

This is a cheap mod, it'll only cost you the price of a cone filter, the filter gets clamped onto the end of the MAF, and the air filter hangs
in front of the transmissions

MarcyMotorsports CAI:

This is the same designed unit as the focussport CAI, but usually you can find these cheaper and they come in different colors.

K&N:

You have 2 options from K&N, the typhoon is a metal unit and all 1 piece and they have a FIPK which is like a composite plastic all one piece... they claim the plastic
doesnt absorb heat as the metal ones and is supposed to produce 1hp or 2 more.. dont know if thats true, but it depends on the engine and conditions also.

Zomk Speed:

T-304 aluminum intake pipe
Come 3" exchangeable stainless steel filter
Cold Air Intake System allows maximum airflow through the stock manifold system
Maximum airflow through the throttle body is reached, and maximum airflow results in better throttle response and more horsepower
Increase 5-10% horsepower
Produce better intense sound under your hood and better gas mileage

HPS:

HPS has in house Dynapack to ensure every HPS intake increase the horsepower, torque and improve the gas Mileage
The HPS cold air intake can help your engine to suck in more cooler air resulting in better throttle response and higher explosive horsepower output
Featuring the 3-Ply reinforced SILICONE couplers/reducers, the HPS cold air intake kit provides stability even the vehicle is in an extreme driving condition

Exhaust:

steeda - sells magnaflow
magnaflow - stainless steele 2.25inch
borla - 2.5inch stainless steele.
trubendz.com - different variations too many to list... check their website... trubendz.com
MBRP - 2.25inch stainless steel.

here is some various information about the duratec focus:

the 05 duratec focus shares the same suspension as the 00-04 focus, so those kits will all work as the same,
but in 06 ford desided to make the front shocks larger in diameter and alittle taller, so 06+ you HAVE to find springs and shocks
that are said to be for 06+ but the rear is the same all the way across, just the front changed in 06.

shifter - any april 2002+ short throw shifter will work... if your car does NOT have the reverse lockout, you can get a lockout delete from CFM.

Pillar Pod - the A-pillar did NOT change from 00 - 07 so if you see a pillar pod for 00 - 04 it will work in your 07. i have one in mine.

strut tower bars - the front engine bay bar is specific to the duratec. newedge and focussport sell them, the rear because remember the suspension has NOT changed,
can be used across the board.

- 2004 foci the engine is an optional feature in all states and remains standard in the Green States (California, New York, Mass)
- 2003 Foci that have duratecs were standard for the most part of that model year.
- No older models have the engine.

The easiest way to tell if you have a duratec is looking at your exhaust manifold. If it is in the rear of the engine bay (against the engine firewall) then it is a duratec.

How can I tell if my car is PZEV-certified?

In the green states (NY, CA, MA) all duratec engines are PZEV certified and carry the equipment. If you are on the borderline of these states it is possible to have a PZEV car. The only duratec in the green states to not have PZEV status is the 05 + ST. Still not sure? The window sticker that came on the car will say PZEV next to the name of the car.

Are there any Short-Ram Air Intakes?

Yes there is the Steeda Ram Air. It adds approximately 5 hp. It's for those who want a decreased risk of hydrolocking. However this setup is still not fool proof. See Egz’s link.

2008 Focus:


As of right now there are few options for the 2008 focus, Ford has once again changed things around. Focussport was succesful with a few modifications to their turbo kit to make it work.

The 2008 focus has a drop in panel filter like the zetec focus, and K&N hasnt released a new panel filter yet.

But on their website they say their short ram will fit it. which i believe. and its good for about 5hp.


---- Originally Quoted by: P0WeRbyDuratec I un-stuck his thread and added his information he typed below, sinse he hasnt been online in over a year and to help reduce a slight amount of stickie clutter.

What transmission is in my duratec?

All manual transmissions in the duratec are identical to zetec’s transmission
The automatic transmission is a zetec variant which is slightly modified to handle more torque. It is the torque convertor I believe that has been modified.

Where can I find performance parts for my car?

Egz’s sticky at the top of this page will show you all the links to all the parts known to fit on this car. It also breaks down the application by your type of engine.
The link: http://duratec.wikispaces.com/Parts_List **New working link**
Engine Designations: D23 - 2.3 L Duratec, Not -PZEV
D23E- 2.3 L Duratec PZEV certified Found in Green States and optional in others
D20 - 2.0 L Duratec
D20E- 2.0 L Duratec with PZEV

What is the best overall starting mod for the duratec?

- This one is basically a matter of opinion. However, most people buy a cold air intake from either Marcy Motorsports or Focussport. Both intakes are extremely popular and cheap. They are your best bang for the buck.

Are there any CARB Certified parts available?

Not yet but some are pending including the Cosworth CAI, K&N CAI.

Is there any threat to hydrolocking?

With every mod done to a car brings its apparant dangers. Modifcation should be taken at own risk. For CAIs there is a danger of hydrolocking. However, if you avoid the deep puddles you should be fine. Many people own CAI’s and have yet to encounter any problems.

Can a bypass valve be used to protect against hydrolocking?

No. There is no bypass valve that will fit on any of the duratec intakes at the moment.The aem bypass valve won't work because you are adding length to the intake setup, Unlike most of the intakes on the market, duratec intakes are designed to be attached to the frame at certain points. Obviously that can't happen if there is a bypass valve. It is also difficult because of the bending of the tubes to go into splash shield It would probably be difficult at best to be able to manage that. Not to mention the diameter difference if there is one between the intake tubing and bypass valve. Those are some of the reasons.

The next best thing is to retain the splash shield after installing your intake

How effective are the Underdrive Pullies offered by Focus Central?

These badboys are a difficult mod to install. This is because the engine is an interference motor and if the pulley is put on incorrectly your pistons meet your valves. If you are not mechanically talented I recommend not attempting this. The mod is only good for a minimal gain at best.

Are there any street-legal headers available?

No this is because the PZEV has a cat inside the stock exhaust manifold. In order to have an emissions legal header, one has to maintain the emissions levels as stock.

What are the options for Forced Induction?

So far only nitrous is the only option. However this is extremely illegal to have driving around town. Fines can be very expensive. Many people have been trying to put a turbo on or supercharger. Powerworks has a prototype of a supercharger. Many companies are working on turbo applications, however a problem lies in that the duratec’s internals can only handle 7 psi of boost. Working around will be beneficial being that incredible gains can be expected. The sister car Mazda3's car companies have constructed a working turbo that have proven to be largely successful, but for the moment that type of modification is limited to not include any duratec focus.

In the future it will be an option.


What is a Balance Shaft and what is its removal do?

A balance shaft are shafts that cancel out secondary vibrations usually associated with driving 4 cylinder cars. These vibrations can be described as the shaking usually felt by smaller engines. Removing them will remove 12 lbs ( I think) of rotating mass which is worth usually 4-5 hp.

What is the best exhaust for me?

It is a matter of opinion, you want to pay for a name? Do you like name brand? Stainless Steel ( for places that get snow) or Aluminum? 2.5 or 2.25"? Can you retain the 2nd cat converter or not? Do you need the exhaust silenced or not. Egz’s site provides a description of each exhaust kit to help you fit your needs.

If you live in an area where there are no smog checks or visual inspections of emissions, 2.5 in exhausts that eliminate the 2nd cat provide the best gains.

What is the Cam Gear Adjustment Tool?

Marcy motorsports has developed a tool that elimantes the need for adjustable cam gears; the stock ones work just fine. This tool will allow the adjustment of your cam gears with simple instructions. Call up Marcy Motorsports to find out the adjustments that fit your application.

I did a quick search through this thread, and couldn't find this information, so please forgive me if it's common knowledge around here. But, you can check the VIN of any vehicle to see what engine it is equipped with. The 8th place in a VIN number is coded for a specific engine. I just spent 20-30 minutes looking through a couple of different model years of Foci, and I think I've got it nailed down.

Z = 2.3L Duratec
N = 2.0L Duratec
5 = 2.0L SVT
3 = 2.0L Zetec

Hopefully this'll help anyone out who's shopping around for a certain with a certain engine/transmission combo (like me).

Anyway, great forum and have a good day!

Review from Sport Compact Car on the Saleen focus:

During our week driving this silver Saleen N2O Focus, something completely unexpected happened: We liked it.

Why is this so unexpected?Well, because we thought we would hate it. And after so many years of doing this for a living, we can usually predict such things. Not this time. This one threw us a curve ball.

Our initial negativity was due to the car's outlandish bodywork and weak stance. Nothing turns us off more. Most of what you pay for when you buy a Saleen N2O Focus is that bodywork, and it's just not our taste even if it is rallyesque. Saleen calls it a race-inspired aero package that consists of Saleen-designed front and rear fasciae, side skirts, fender flares, a hood scoop and a Saleen twin air-foil rear wing. We dig the hood scoop and the center-exiting two-pipe exhaust. You can keep the rest. If you like the way it looks, you probably think Paris Hilton needs bigger boobs. We're ass men.

What really bugs, however, is the car's lame stance. The 17x7-inch TSW Revo wheels, which are six-spoke cast-aluminum pieces, just aren't wide enough to fill the car's now radically flared wheel wells. We've never seen a rally car with stance like that, and we hope we never will. It looks like Schwarzenegger's torso walking around on Christina Aguilera's legs. We're told 2005 models wear unique wheels designed by Saleen.

Wrapped around those wheels are Pirelli tires measuring 215/45ZR-17. Our test car wore optional and supersticky R-compound Pirelli Corsas, which certainly add to the car's performance and are a steal for the $475 they add to the Saleen's $25,999 MSRP.

Another option worn by our test car is a front brake package. For $1,365, 13-inch vented front rotors with Saleen black enamel four-piston calipers replace the stuff Ford bolted on at its Mexican plant. Every Saleen N2O Focus keeps its Ford-installed rear drum brakes.

Our test car was also optioned out with an Alpine in-dash stereo/DVD, which adds another $2,744 to the car's sticker. We're told it sounds great. Too bad we never figured out how to use it.

Thankfully our silver tester was without the optional Saleen extreme rainbow paint, which costs another $16,000, and can cause blindness in small children. Tallied up, our test car carried an MSRP of $30,583, which is quite a load of cash for a breathed-on Focus ZX3 PZEV.

OK, let's get to the good stuff, which is underneath, inside and under the hood.

Included in the purchase price is an excellent suspension package engineered by the folks at Saleen. Like the Saleen Mustang for which the company is famous, the PZEV Focus is delivered to the Saleen facility in Irvine, where it's transformed into a Saleen. Part of that transformation is the installation of all-new suspension bits the company calls the Saleen Racecraft System. It includes stiffer dampers and coil springs all around, larger 1.25-inch front and 0.98-inch rear anti-roll bars with urethane pivot bushings and a front strut tower brace.

Although we've ridden in Saleen Mustangs with the compliance of cinder blocks, that was years ago. Things have improved to the point of being impressive. This car rides as well as a stock SVT Focus, which, if you haven't heard, Ford has killed, yet mightily outhandles the factory hot rod.

Circling the skidpad, our tester worked its front Pirellis like it hated them, but recorded a very stout 0.97g. Then it tackled the slalom at 73.1 mph, exhibiting good balance, quick reflexes and awesome stability.

Those numbers not only stomp our Project SVT Focus, which managed 0.89g and 71.5 mph stock, but they're also better than we managed in both the EVO MR and WRX STi we tested last month.

Such grip requires good seats, and Saleen delivers. A perfectly shaped set of Momo chairs is part of the package, as is a Saleen shift knob, white face gauges, a short-throw shifter and custom floor mats.

The Saleen's braking performance is also strong, despite those silly rear drum brakes and a lack of ABS. It stops from 80 mph in 194 feet and from 60 mph in only 108 feet. For perspective, our SVT stops from 60 mph in 120 feet, and the EVO MR stops from 80 mph in 200 ft. Again, the Pirelli Corsa tires are helping here, but numbers are numbers. Heat did become an issue after several stops, but pedal modulation before everything overheated was very good.

For power, the Saleen N2O Focus relies on a dead stock 2.3-liter DOHC four that Ford calls the PZEV and rates at 152 hp at 5750 rpm and 155 lb-ft of torque at 4250 rpm. Then Saleen installs a direct-port 75-hp wet nitrous system from Nitrous Pro Flow with a 10-pound bottle mounted in the cargo hold. Hence the name of the car.

But there's a catch. Although all the nitrous hardware is installed, it's not hooked up, and the bottle is empty. Saleen delivers the car "nitrous ready." And here's the catch. Once you hook it up, which Saleen says will take about an hour, your engine warranty is void. Too bad, because it works. Check out the acceleration numbers.

In an attempt to keep the car's engine in one piece, the nitrous system is engineered to kick in at wide-open throttle above 3000 rpm only, and shuts down just before redline in an attempt to keep the engine from getting spray without enough fuel.

Without the spray this car is slow. Its engine is smooth and surprisingly torquey around town, but it's slow. Even slamming through the Saleen's five-speed manual (a four-speed automatic is optional) like Dick Landy doesn't help. Nitrous off we recorded a zero-to-60 time of 8.2 seconds and a quarter-mile pass of 16.1 at 84.3 mph. Juice on, things improved righteously, however. Our best time was a 14.6-second pass at 95.6 mph. Zero to 60 improved almost two full seconds to 6.3. Saleen says the car, which only weighs 2,620 pounds, should run a 14.0 quarter mile with the nitrous hooked up, but we couldn't manage it, even with a fresh clutch.

Another change for 2005 is a switch to a 2.0-liter engine, which Ford rates at only 138 hp, but Saleen says its exhaust and unique reflash of the car's ECU gets the power back up to the 152 hp of the 2.3 liter in our test car.

Overall, this car performs well-very well-but it's expensive. For the money we'd rather the consumer get more substantial engine mods with a good warranty and more complete brake system instead of the custom floor mats, the standard Saleen key fob and an Eagle One detail kit. But that's just us.

Steve Saleen has produced more than 8,000 complete and EPA-certified vehicles since 1984, more than any other specialty manufacturer. So he's no dummy. He knows what the people want.

Next on the list is the Intake thread:


With the recent bloom of many threads about cold air intakes for the duratec i thought i would make a thread for them:

Cold Air Intakes for the Duratec Focus:

Focussport:

FocusSport™ 2.0L & 2.3L Duratec Cool-Flo Race™ Air Intake System
This is a true "cold air" intake system that situates the filter in the lower front region of the car, away from ALL engine heat. The Cool-Flo Race system utilizes 3" mandrel bent steel tubing along with laser cut bracketry. Other features include all tig-welded construction and coated with silver powdercoat.

$219.95 - 8.4HP


K&N typhoon Short Ram:

Built for performance and show, the Typhoon™ Air Intake System is a free-flowing mandrel-bent aluminum tube induction system designed to fit many sport compact performance vehicles. Typhoon intakes come in one of three designs; cold air intakes (CA), short ram intakes (SR), or complete cold air (CCA) intakes which can be configured as either a cold air intake or a short ram intake. Some Typhoon's have high quality finish options including polished aluminum (part ends with TP), powder coated blue (part ends in TB), powder coated red (part ends in TR), and powder coated silver (ends in TS) among others. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction allowing more air flow to your engine. More air means more usable power and acceleration throughout the engine's RPM range.

$270.95 - 5.24HP


Steeda: (this is technically a short ram intake)

Focus Owners - Be Advised: this is not just any cold air intake kit, this is a Steeda Autosports cold air intake kit. What does that mean for you?

It enhances performance
It looks great
It installs easily
It's your best value
Our Dyno, below, showed six more ponies at the wheels of our Executive Cruiser, and nearly four more pound feet of torque with our Cold Air Kit for the Focus Duratec engine - without re calibration or tuning the engine further. Should easily make even more power on modified engines as well.

The kit includes a precisely machined billet aluminum MAF sensor and handsome stainless steel guard with the stylish Steeda logo laser cut into it, along with a Steeda life-time, reusable filter and all the hardware needed to replace the original factory intake.

Installation is a snap - simple hand tools are all you need to do the job in about an hour, following along with the illustrated instructions provided. When you're done, you'll find that the 'wow' factor under your hood has gone way up as a result of your efforts.

And when you compare this kit to others available, the value becomes clear. Why settle for a glorified hunk of pvc pipe and a new filter element, when you can have a brand new, billet aluminum CNC machined MAF sensor, a reusable filer with lifetime warranty, and a stylish, stainless steel guard instead? Get show and go for the same buck - that's the Steeda Autosports formula for high performance value.

$206.96 - 6.3 HP


K&N typhoon:

K&N now offers it's popular Typhoon intake for the Focus with the 2.0/2.3L Duratec engines. Polished or powder-coated tube adds a little "bling-bling" under the hood as it helps to increase horsepower. Also helps to increase gas mileage...if you can "keep your foot out of it!" You'll love the increased performance and that "high-performance sound", you may not be able to resist putting a smile on your face every time you put your foot down.

Kit comes with either a polished or powder-coated tube, world famous K&N cone filter, K&N Drycharger to help repel water, connector, hardware and allen wrench to help with the installation.

209.95$ - N/A


K&N FIPK 2:

The Generation II FIPK® is K&N's ultimate performance product, designed to increase power by as much as 10%. Most FIPK's are street legal in all 50 US states and come with a Million Mile Limited Warranty. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available

$291.69 - 11.85HP


AEM:

AEM pioneered the Cold Air induction system for sport compact cars in 1994.

A Cold Air intake system relocates the filter outside of the engine compartment to deliver the coolest air inlet temperatures possible. Cooler air carries more oxygen, which translates into a more intense explosion in the combustion chamber to create more horesepower and torque. But that's only part of the power equation. Tuning the inlet pipe in length and diameter to match the engine's resonance helps move more air to the cylinders (think of your engine as a big air pump), and no company on the market can tune an inlet as well as we can. We also monitor fuel trim correction factors and all OBDII sensors during R&D to eliminate leaning the engine out and/or throwing a check engine light.

Our Cold Air systems are dyno-proven and tested against the competition to create more useable power than any other system of their kind. Every AEM Cold Air induction system features the highest standards of construction and we are so confident in their fit and performance that we guarantee them for the life of your vehicle. All AEM Cold Air systems are either 50-state legal or pending (excluding "Off Road" and "Hybrid" systems), include a lifetime DRYFLOW Synthetic air filter and come with a limited lifetime warranty.

$291.41


K&N FIPK:

A sister product to our 57 Series FIPK, our 63 Series Intake Kits or AirCharger® Intakes are built for many different vehicles and represent a dramatic improvement over a K&N O/E replacement filter alone. They enjoy a faster speed to market than our 57 Series kits due to their pending CARB status. These intakes use only non-metallic rotationally molded tubes that can reduce intake air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter. The weakest link in the airflow "chain" robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the Engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER. 63 Series Intake Kits are not legal for street use in some U.S. states.

$273.95 - 11.85HP


Cosworth:

Cosworth Roller Throttle Assembly (YD8070)
For maximum power and performance, Cosworth has developed barrel throttles with an integrated manifold for the Duratec engine. This F1 style throttle provides complete control with un-restricted flow at full throttle. Cast from heat treated aluminium with CNC machined barrels supported by sealed bearings. Shown with optional carbon fiber air box and filter kit KK3599

$2040.00 - N/A


Cosworth:

Cosworth also had a Cold air intake for the duratec focus. but they are no longer being sold, you may be able to find a used one, they come with a K&N style air filter, replace the factory MAF tube, it is all anodized blue, and you can expect to see a 10 - 11hp increase.

Black empty box in 2005 zx4 intake????

What the heck is it? Is it the place where squirrels sucked into the intake get stored before entering the throttle body?

I am interested in a CAI, but I am trying to avoid a major job. And (wonders never cease) I am not looking to spend hundreds$$$. Imagine that?

What is that box if not just a place to put the filter monitor? Dumb Ford Idea if that.

the lower one is the actual air filter.....

the upper one is where the tube goes through, and is also the carbon chamber.

HTPerformance sells parts for the Duratec. Most all our R&D now is for the Duratec. We have also done the swaps with many more interesting Duratec setups on the way. :)

Greatly appreciate if you could add us to the list. We are also a sponsor for this site :)

is it possible to port out the stock one and replace the butterfly plate with a larger diameter one to accomidate the larger bore. all you would need is a dremel and to machine a new plate. i now its easy shop work to do but is there anything in the internals of the tb that would prevent porting it? ie. coolant or cavities or anything like that.

Yea, don't bother. The only modification seems to be worthwhile with the ETB is to add a ground wire to the housing. But other than that, you won't get anything. My Focus builds use a stock TB. FocusSport and their 400hp STC project car used a stock TB.

thats true but wouldnt the general idea still apply though? i understand that the tech may be optimized, but seems like it opening it up just a little would still help. yes its a small mod but thats all a p&P really is, a small mod but you still see gains from it too.



i'm not trying to argue just debating in search of knowledge. ;)

A lightweight flexplate won't really make any difference as it is already very light and it is bolted to the impeller on the torque converter. Its not like a flywheel where the pressure plate can separate it from the trans. What exactly are you trying to accomplish?
