: Turbo or not to Turbo?
01-27-2004, 02:03 AM
ok I have recently bought a 2002 Focus Sedan - and I have the 2.0L SPI engine - I will be instaling headers and Cold Air Intake on a new throdle body, My question is this - is it possible to get a Turbo for this engine? I have yet to see a kit for this motor.
Current updates to my car 17" ChromeTech Rims on Falken 215/40/R17Z tires - Mod chip from previous owner - current top speed 144MPH (As per Texas Department of Safety).
I am looking to boost my 0 to 100 speed this is the only area of concirn I have - also rate the cat - back differance from APXI or should I stick with G-Ready.
Pics to come soon in new reply soon as the car gets a bath :P 2000 mile trip in 2 days - its a car o bugs right now.
Purchased Euro Tail Lamps - ElGlow Gauge Kit - and Halo Projector Chromed Headlamps to be installed next week. Pics of that also on my site as they are completed.

nope not turbo out, could go custom but cant promise itd be worth it.... best bet is just deck it with bolt ons, get a cam gear, tune it, and be happy till u can get somethin better

there are many spi turbos on focal jet go there and ask them, also there a guy on here that is planning on turboing his.
his name is waterboy u can try to ask him.

I go by that here, too.
Thanks for the props, but I'm not all that.
I will answer what I can, though. The SPI is a capable engine that can handle 5-7 psi easily. The ECU can also handle the new parameters for fuel, and the variable speed fuel pump in the SPI can handle the extra juice needed to cover the larger injectors. The stock internals will do fine to avout 170hp, but if you're intentions are greater, you need new pistons. No-one currently makes SPI pistons (as far as i know), but there are companies that will make a set special for you for about $450. The Escort RS in England is your best bet for bolt-on turbo parts. The manifold is a bolt on, and the charge pipe is the trick if you don't go intercooled. For 5-7 psi you don't need to intercool, but for much more than that it is a good idea. The 2.3 oil cooler bolts right to our filter threads, and the filter screws to that. You'll need to plumb water lines to the turbo, oil cooler, and back. You'll also need to plumb oil lines from the oil pressure sensor to the turbo and then back into the oil pan. I removed my oil sensor on the back of the block next to the oil filter, screwed in a nipple, then a tee, then the sensor and an oil pressure gauge into the tee.
For fuel, our pump is fine, unless you intend on 200HP +. The fuel rail is fine, but the injectors will have to go. Currently I have ZETEC injectors and wiring, but even those are way too small to prevent detonation (BAD!) Most guys I know run 42# injectors, a stock MAF (but recalibrated), a chip, and go to a fella named Lidio in Detroit. He's tha absolute best when it comes to turbo tuning. If Saleen sends him rolling chasis to build monster engines for, he's surely good enough for me! He has an 11 second F350 Super Cab dually Power Stroke if that tells you anything. The 5v cutout on the MAF is where we need to have work done. That's why we need a chip and tuning. Without those, your car will be a mess.
I'm running -40* Below coolant additive just to make sure everythings "cool", and Mobil 1 just for the fun of it.
For the exhaust side, anything over 2.5" is overkill. I know a few ZETEC turbo guys who run the Magnaflow 2.25" with no problems whatsoever. They hit 14+psi on stock internals. A header can be converted using a turbo flange, or you can go the RS route.
Head work is not necessary, but every little bit helps. I just had mine done and it runs about $300-400 for a full race P&P. I also have ARP head studs, a good idea if you intend on pulling the head more than once while you own it. I just wish I had the time ti install it! Damn snow!!
A good cam would do you justice, even if you decide not to go FI. I have the Escort/Focus setup. While pricey ($470), it has made a nice difference in the engine. Their setup consists of cam, double valve springs and retainers, and new stem seals. It pulls to 7k and acts like it could go higher. My chips rev limiter is at 7k.
Keep this in mind: If you have an automatic tranny, forget it. The tranny is rated at 135 lb/ft. It can't handle the extra horses and torque from a turbo. Level 10 makes a tranny, but it's somewhere around $3500.
Fell free to PM me or pop on over to FJ and chat with the guys who are also well on their way or have already gone turbo with their Escorts.

Ok so if I have this all right - without going turbo I can still add alot of kick to this SPI engine - unfortunatly I do have the Automatic Transmission and acctually perfer to keep it. ( I know its silly ) but I have no faith in Fords Manual Transmissions. I will look into what I can do with this transmission to allow it to handle a little more juice from the motor. I do appreciate all the input and I will let you all know what I do as I go - I am very fond of the idea of larger injectors and new cam and lifters *ROLLERS?* but I will look at it all and see what I can ballance out with power and value.

I, too, have the automatic tranny. It has taken a HUGE amount of abuse and hasn't let me down yet. The Diablo chip seems to work with the SPI fairly well. The one I have is based off the LFQ ZETEC program and has been modified for the SPI. It is available through FocusSport. If you need to, call there and ask for Randy. He's the VP of FS and will help you wherever he can.
I also bought a second tranny cooler off Ebay. It's a stock cooler but I have tucked it behind the upper grille and plumbed the two together. Then I refilled the system with B&M Trick Shift just for giggles. It hits HARD. Not a bang, but a solid shift.
There are some shift improver kits out there, but I haven't tried any yet. I think there's one that lets you control the torque converter lockup. I don't know right now what's a gimmic and what's for real when it comes to that stuff, so I have let it be for now.
If you decide not to go turbo, there's a TB, header, underdrive pullys, cams...whetever you fancy...Jeez, did I just say that?? I have a TB from a Mustang GT and it works fine. There was a little machine work involved and a phenolic spacer needed to be made, but all in all it works fine. My Magnaflow I got from a ZX3 and added a 6" extension between the muffler and the tip. Works fine and no-one is the wiser. You can trick the MAF to think it's getting colder air with a resistor spliced into a MAF wire. Works the best of all the mods I have done so far. Costs about $2 to do, too. I guess before your head turns to mush, make this your mantra: Air in, air out...repeat....Keep that in mind and you'll do just fine. A word of caution: DO NOT GUT YOUR CAT! It creates so much turbulence inside the cat that the exhaust actually gets slowed down, thus robbing power. I can tell you this from firsthand experience. I ran almost a full second slower at the track.

from personal experience turboing a nonturbo car is a LOT more than just buying the kit. There are so many hidden costs and other things to take in consideration when doing so. Really do your homework before jumping into it and make sure you have the finances to keep your car running reliably after you have the turbo on.
Boost is like crack, an addiction that can kill your car.

I agree. My response was oversimplified. There are a lot of parts that need to be fabbed or modified just to get things rolling. Then a huge amount of work for fuel management. Then it still needs tuned. I don't know anyone who will touch an automatic yet because they worry about it scattering. I tend to agree with them. The automatic is the weak link, and there are only two companies that do aftermarket high HP Focus automatics. They are expensive as hell, too. It can be done but you need to be part bloodhound to track down the parts, a machinist to make others, and patient as heck.
Go for it if you are like me. I HATE it when someone tells me I can't do something. I'll do it just for spite.....
