I'm just curious what kind of power the Duratec owners on this forum have gotten out of their duratecs.

I did do a quick search and couldn't find any other threads.


They reason I want to know is I'm planning to be running upwards of 400 hp by this coming summer, and I'm curious if anyone else on here has come close?

Just post your max hp [please, 200hp and up] and what you did to get it. Also, even if you only 'heard' that someone was running real high hp let me know. I want to see if anyone besides the major companies have done this.

Ehh, FocusSport did it, and also sells the kit that they did it with, for $200 more than a Stage 1 & 2. Theres a number of people who have gotten close with the zetec (turbo turtle ran 354 hp on 93 safely, on 24 lbs), but I'm plannig on running 24-26 lbs of boost. Most likely on 100 octane. FS did 400 hp with 26 lbs on 100 octane, with stock cams and the stock fuel pump and the 2.0 duratec. They actually made more power with the 2.0 than they did with the 2.3.

But we'll see what i actually end up with...400-ish is the goal, I'll be happy with 350 hp on 93, and I KNOW that can be done.

Don't forget the 9.0:1 pistons, forged rods, Cosworth IM, head work, 2.5-3.0" exhaust...

Out of straight curiosity, what are you starting with (garage/part/car-wise), and how much money are you planning on throwing away on this? I mean, drop in the 'Busa V8, the 3.0-3.6L Dura V6 that's hardcore built, whatever, but on a 2.0/2.3L I4, you're talking about an overly abundant cash flow to even *begin* this...

But good luck, nonetheless...I'd love to see it done on a non-garage budget...

should go to cosworth.com and see the engine builds they have from the other side of the world i think, for bout 11 grand. think it said 250 hp out of a duratec engine. they have the 2.0 dur and 2.3

It can be done & streetable. First things first, do you need it to be street legal in your area? If emissions is not a issue, you"ll need to know how much money it will take to get a built short block (a necessity for those hp goals) & if your current fuel system can support 350whp safely. When you get pass these points go from there.

Those also have the roller intakes that make it pretty much impossible to go F/I with it. After some serious compression and tuning, you *might* be able to get one of those blocks to 300-325. Keyword there is *might.* It would take some pretty ingenuitive engineering to do it.

Even with swapping out the intake manifold for their other, you'd sacrifice the gains from the rollers (25-40hp), and be able to gain F/I (+50-75% on a good day). That puts you at 300-385. Gaining that last 15 (assuming everything you do is perfect and dead on highest-gain possible), is going to be the hardest 15 you could probably think of. My only thought on it would be to add a 25-50 shot of NO2, and by that, you're going to blow your motor out. It's not a question of if, just a question of when.

This is also assuming you've made the mods to your transmission so it can handle the power you're going to be laying out. This will also be on a stock suspension since you haven't even started talking about it yet, so there's another $1k-1.5k, then tires that won't slip under that torque. Sure, you could pass on these, but why would you want a 400+hp in a car with a spongey suspension and all-season wal-mart tires?

As I said before, I'm not trying to discourage you, just trying to point to you what kind of hurdles you might be running into or clearing with ease. I would honestly LOVE to see it, and I'll chime in anytime I feel like I can add something, but a 400+hp duratec, *especially* a 2.0, is not a simple undertaking and is going to take far more planning than chatting with a couple weekend warriors that have thrown intakes, exhaust, STS, and *maybe* cams and a tune onto their cars over an internet forum can give you.



EDIT - A caveat, the numbers I threw out before are based solely on estimations, and generous ones on that, so flaming would be quite inappropriate. I have no idea what those guys that have thrown down 350+ have done on their cars, and they know FAR more than I do. I'm merely basing this on what seems right in my mind and you would be better off to go chat with on of them.

ya but the cosworth engine's are a HC engine's like there 300 hp n/a engine had 14 to 1 compression pistons in them. so F/I would be th way to go but your going to spend a hefty penny. but the 11 grand engine is just a waste of money b/c you can make one for half of the price an get the same amount of HP.

if you started from a roll you might have enough grip.....but from a dig you wont have enough grip. so 400 hp on a FWD ummmm no.

Guys, I know I'm going to have the BUILD the engine, and that is in the works before I even buy the turbo setup. I'm gonna be buying a block sometime in the next month [upgrading my brakes first, I want to be able to stop before I can go fast], and building the block. I'm not sure one what brand I'm going with for everything yet, I still need to do more research and talk to the people who HAVE run 300+hp.

Going to run 9.0:1 compression, forged rods, probably cams with a slightly higher lift than stock but stock duration, ARP head studs & cap/rod bolts. Not sure what I'm gonna go with as far as a head, or intake mani, but theres plenty of time left for that. I'm looking into sleeving as well. A friend on NEMotorSport told me that he thought the Duratec might be factory sleeved (I'm not sure). If it is, theres a guy about a half hour from me thats sleeved a couple of high boost cars that no one has had any problems with.

Turbo is going to be a GT2871R, with the FocusSport turbo kit. Also will use their Stage 2 intercooler, as it's what they used on their 400+ hp Focus. Plan to be running 24-26 lbs of boost.

Transmission is going to have an LSD, probably the Quaife but not 100% on that yet. Clutch is obviously going to be upgraded a ton, but also not sure on the brand. MIGHT use the 4.10 gear set, but if the car isn't going to hook up with higher gearing, it certainly isn't with the 4.10's. Is there anything else to do to the tranny that anyone can think of?

Suspension: Getting dropped probably 2"-2 1/4", coilovers most likely. Sway bars, strut tower brace, traction bars, the whole shebang.

I'll run the wheels I have now (with better tires), 17X7.5's until I can find a wider wheel besides the RS wheels. Plan to flare the fenders out (RS kit?), but will be fine til I have the wider wheels.



Yes, I know I could do an engine swap etc etc, but I want the ease of installation. I'm going to have a big enough pain getting this thing tuned perfect, I don't want to spend 3 weeks getting a new motor in and running.

Why do I want to do this on the 2.0? Mainly because no one else really has. I love my car ('05 ZX3, 5-speed), and I don't want an SVT-Zetec or a Zetec. People have already done this on the zetec, and most agree that the Duratec is a better engine.

I appreciate the input that CapnGnarly gave, anything like that is helpful. Question, and offer suggestions please, but don't tell me it can't be done...Tell me how you think I could do it. Don't tell me to do an engine swap, recommend a suspension. Give me ideas, and help me make the right, educated decisions on what parts to go with. If you don't know something for sure, SAY SO. I'll do research on whatever people think might work. I've been planning this for months, and continue to do so until the whole car is done.

Thanks for the input guys! :)


*EDIT* I have a 24'X48' garage at my house full of tools [my dad used to work on old musclecars, now into high performance boats), as well as 3 friends with similar size garages. One of my friends is going to school to be a mechanic and has already done a few engine builds, he also has access to his school garage and tools. He's gonna be cleaning up the block I buy, and he's going to be the one installing most of the parts. A few of my other friends have done turbo builds, and between allof that, if we can't do something then I will pay someone to do it...theres plenty of reputable people who specialize in engines around here.

And money, well, I'm far from rich. But I have very limited bills, so all cash flow is pretty much disposable. Between the engine, turbo, drivetrain, and suspension I'm looking at probably $15,000. Yeah, thats a lot of cash. Sure, I could go buy a car that'll be just as fast for the same money. Could I say I built it? Nope. Would everyone expect that car to be fast? Yep. Who the hell is going to think that when I pull up next to them @ the track, or on the street, that I'm pushing 400hp? My point exactly. I don't expect to get my money back, but I do expect to enjoy the car and make that money spent worthwhile.

all i can say is good luck and i'd love to see this done

hopefully it will have usable power and won't just be a "dyno-queen"

If it is, I'll cut the boost back until I can find a way to get the power down. I'm sure someone would come up with a solution eventually :)

Sounds like you have all the right ideas to build a beastly focus, lurk over on FJ to get some direction on the build. And dont let anyone change your mind, this will be badass [thumb]

Sorry. I'm kinda new to the focus game. Could somebody explain why it will be so hard to reach 400? I know a guy that had a 1.6 SOHC that was quite built and boosted that put out 300+ hp. I am just wanting to get to know these motors a bit better. Sorry if this is stealing the thread. Just curious.
