I'm very interested in turboing my Focus. I know Tom has a full kit but I was looking at the Focus power website and there is also a "DIY" kit option for $1500. This is a better price for me compared to the $5k for the other kit. I was also looking on Turbokits.com and they have a universal kit that seems decent for $1800. Does anyone know what comes with the DIY kit from Focus power? The site only has a couple pictures and not much of a description. It looks as though all of the essentials are included but I don't want to commit if something crucial isn't included.

Tom is Focus Power.

I couldn't find anything specific, but based on his kit for the 02-04 DIY conversion, which I'm assuming contains similar hardware, it looks like you get exhaust headers, intercooler and all relevant piping. So you'll still need to purchase the turbo itself and probably a BOV, definitely a tuner and tune and a few other goodies.

Tom's kit will be the best by far. (Focus Power)
Also Tom's kit comes with unlimited tunes which is crazy nice. Can not be understated.
Also Tom has been tuning these engines for a very long time.

The DIY kit does not come with a turbo, just all of the pipe work (which is big part of the battle)
Crucial: a turbo, turbo oil lines, downpipe, and a tune ($$$$, $$, $$, $$)

But without building out the motor, you'll be capped at like 15 psi of boost? I think?
Stock Ti-VCT come with cast Rods which puts limitations on your turbo build unless you upgrade internals. Just gonna throw out 300 whp as the breaking point. I can't imagine 400 whp on cast rods.

If you want a motor with forged rods, you could do an Ecoboost swap.
Find a salvage 2.0L ecoboost (from escape, mkz, fusion, focus ST)
Pull the engine (turbo included) (wiring harness included)
Pull the charge piping
Pull a ECU. (ECU has to be from a focus ST)
Stock ST motor can handle up to 440 whp before anything breaks. Stock turbo only good for 290 whp but drop in turbo kits are much easier fit

For the price you could maybe do the Ecoboost swap cheaper. But if you want the best plug and play solution to get your focus pushing 300whp to the wheels then you gotta go with Tom's turbo.

Huge help! Thank you. I'm not looking to do anything over the top crazy. I'm not looking to build a track car or anything, just a fun weekend car to cruise in. 300 whp will honestly be more than enough for me. I just think it would be fun to make a little something out of a little SE. I'm a "go against the grain" kinda guy, and this would just be fun to do

Good point... Looking at post history, he's got a DCT on a 2012, which will limit him to 190whp if memory serves.

@GilgaNess_MK3 if you want to hit 300whp, plan to replace that DCT as well. It's probably your biggest limiting factor. Habrient's suggestion to find a used 2.0 Ecoboost and swap it in might be your best option from a cost standpoint, assuming you can pull whatever transmission your donor has as well.

Many will say to go to a ecoboost , it isnt cheaper , you have to pull the entire dash change ALL wiring one company if you provide ALL the ecoboost swap parts charges 8000.00 to do the swap

Going Turbo isnt cheap , I like being different , I parked with 2 RS and 3 ST the other night and had 10 times more people looking at my plane jane looking sleeper 2013 Focus SE Custom 2.5 L Engine Turbo Charged then all the other Focus there

Look around , see whats out there and make a decision

Thank you! I saw one guy who simply installed an ebay turbo on his focus and it actually functioned ok until the fool hit it with 26lb of boost and through a rod. I don't want to be stupid about this but I know it can be done. The full kit you have honestly looks really nice and com8ng with unlimited tunes is great. I already have an SCT unit, would I still have to purchase the one that comes with the kit, or is it possible to subtract that out of the cost?
What do you think my best option regarding the DCT is? I would honestly love to swap it for a standard but from what I've seen that's a pretty involved process.

I love the idea of the sleeper Focus. If I had more time and money, I'd have made that myself instead of buying my ST, but I wanted something a bit more reliable as a daily driver and something super easy to get support for. Once you get started, make sure you make a build thread! I'd love to see the process start to finish.

I dont know of anyone that has had PCM issues why Tuning , Im sure somewhere some one has but its super rare

Tom
Hey tom can you message me I have a 2012 Ford focus SE 2.0L with cone filter, muffler and resonator delete , and ngk plugs. I have sct x4 tuner and I need someone to make me a tune and give me pointers on upgrades to gain more power please get back to me asap chiraq7775@gmail.com

A safe limit is 300whp the big issue is the HPFP and it needs to be changed

The oil squirters play such an insignificant if any part in engine safety that I havent even looked but I think there in all Duratecs

Nice thing about adding a Turbo kit is you dont have to deal with the undersized Turbo the ST has and the crazy amount of boost you have to run to make power , 18 psi = the ST 29psi in whp actually it makes more TQ where its needed above 4000 rpm where the ST tanks in TQ

How did you use the access tuner to gauge head bolt stretch ?

Yeah the interesting yet restrictive headfold concept definitely has its limits. I've always thought a traditional 4 port exhaust to manifold set up would be able to make more power on less boost. Glad this is true. I could see the 2.3L ecoboost head actually getting somewhere, but the first gen 2.0L definitely has a challenge due to the tiny single exit.

When I got my 2013 ST I decided to get accesstuner and learn how to tune. (I'm an engineer. I said screw it I'll learn.)
The used ST that I bought had a forged short block.. which I mistakenly thought included head studs. Just started tuning. Had no idea what I was doing. Said "ehh those 'ARP head studs' should be fine.. lets crank it up". Turns out they were OEM. They are ARP now. hahahaha.

I'm running a hybrid turbo to help it flow better up top, but really only use 23psi at 4000 tapering down to 19psi at 6000. The whole "shoot for 29psi" was foolish. its better to run less boost, more timing. But people with bigger, less restrictive turbos will stick around 25~30psi through the whole band.

I'm still curious what the HP limit is with the stock DCT trans. I know that dry clutch design was kinda crap and, from what I can find, the trans is nearly maxed out from factory. That'll be a huge determining factor in how OP moves forward. If you stick with the 2.5L engine, you'll need to find a 5 speed from that year, if you go 2.0 Eco, you'll need that tranny instead.

From what little research I've done on the DCT, it looks like adding any power to it at all is a risky venture.
We dont know the limits of the DCT , I have one that made 323 whp and still pulling

The DCT Clutch design had NOTHING to do with its short comings , Its all software related

The S , SE , Tit , ST Duratecs 2.0 , 2.3 , 2.5 , Ecoboost Blocks 2003 to 2018 all take the same Trans Bolt Pattern

Where are you getting 2.5 From ?

Yes I dislike the ST I have owned a few of them and own one now , My 2002 SVT stock Engine Turbocharged will out run , Out handle ,out brake , Rides better , Looks better , worth close to the same money , lower Insurance and I could go on

The ST is under powered , makes less TQ at 7100 then a NA SE , Under Turboed , over priced , rides like crap , seats such , to heavy , Trans is crap and I could go on

Yeah nothing turns heads like a well done mk1. Its why I didn't sell the 05' ST you tuned for me.

I love my 2013 ST though. The extra weight is nice for the daily. and its got better NHV....
BUT i have added BC coilovers, Carbon Fiber Syncrho trans rebuild, a whole ton of shift linkage modifications. better Brakes, better tires. better tune. better turbo. Forged internals. on and on and on..

I have no interest in debating ST vs turbo SE with you any more. I already know exactly where you stand and understand you will not change your mind or budge even the slightest bit on your views, regardless of any evidence, so please stop bringing up how "bad" the ST is and how your cars are better in every single way perceivable. Different strokes for different folks. Not to mention, no one here has suggested OP just buy an ST, so you're just pulling it out of thin air this time.
To quote a wise man, "That's just like, your opinion, man."

I guess I should be more clear. The DCT is topped out (according to documentation) at around 200 torque. Technically, I suppose you can make a car with more horsepower while not exceeding that torque, but who doesn't like a torquey car?

I got 2.5L from an assumption that his focus is the NA 2.5, though I could be wrong on that admittedly. Ford sold this particular model with way too many engine options... Lol. @GilgaNess_MK3 which engine are you running right now?

The rest of your post, I'll ignore as it's tangential to what OP wants to discuss, and is mostly opinion anyways.
 
#29 ·
LOL it isnt opinion its fact weather you like it or not thats how it is , As for the DCT and its TQ limit Ford said the MTX-75 wouldnt handle more then 275tq and it holds over 500wtq and again I have a few DCT well over 200wheel tq vs Fords 200 Flywheel TQ rating one over 3.5 years now

Why is it always the ST guys that get butt hurt that a SE can out performs , out WHP and rides better FACT , AGAIN I HAVE A ST TO COMPARE it isnt like I am pulling this out of thin air like your doing
