You can't "make an STi" out of a WRX.

For more power just put in a bigger turbo and all the supporting mods. This should cost you less than the price difference between the two cars.

Of course, you still won't have the suspension, brakes, interior, etc, etc.

i know..but im talking about just beating it in general..
i heard with uppipe, downpipe, exhaust, boost controller, and a STi top mount properly tuned you can catch up to a STi no problem?

Yea that's true but it probably won't last as long.


And remember, you can mod an STi also

Ask Jamie

Edit: In my old RS-T, I was able to be neck and neck with a stock 04 STi until about 120km/hr then he pulled on me.

i would say don't be a minimalist....the better supporting mods you have the more effiecent and reliant your power gains will be

...plus you don't want to be overworking so many stock components

FUKA: you paced w/ an sti in your rs-t??? i have to see to believe

there are lots of WRXes that can keep up and keep away from a stock STi.. but it just takes the right mods and the right driving (keep it in the boost). Saying they wont last as long is very misleading - equally maintained and setup I will go as far to sugest that the STi will fail first on the rod bearings ! Its doesn't take that much and you dont need to do anything to the internals. Its not just engine, ratios will help you here too.


but from standing starts, the WRX suffers from the tranny.

Yup. I launched it at about 3500rpm right off boost and it jumped. The stock clutch slipped on 1st and a bit on 2nd. Then at about 3rd gear redline (in my car), the STi pulled on me....and it pulled hard.

End of the day, yeah, you can easily build a WRX to take over a stock STi. But I'd much rather start from scratch with a 2.5L turbo'd motor than a 2.0L. Even if you were to stroke the WRX motor to 2.2L, it'd be pricey and...well, I'd much rather start with a STi and build upwards.

I've seen guys dump a ton of money into NA 2.5's and 2.0's. They perform well, but the sti just gives such more variety to get more power. If you want the power with all the goodies best bet is an sti. The wrx at stage 2.5 for example will stay ahead of an STi (from experience). But, remember the wrx has longer gears and only a 5spd which gives it a bit of help (less shifting) on straight line dragging. You can't make up for the torque that an sti puts out though. But if you compare a wrx to a sti in dragging, a wrx with turbo upgrade, bigger injectors, exhaust and a good tune will be quicker than a stock sti. But then again, a modded wrx vs a stock sti in autocrossing, track racing etc... will have a different outcome for sure.

no matter what you do the tranny will be your limit, it doesnt take much to get 300+ hp but you need to be able to stop properly and get the power to the ground. The engine can take 300+ but you will likely blow your tranny shifting hard trying to keep up with the STi.

ps like J said an STi is more than a motor it is all the supporting things.

04+ WRX's tranny's have sti RA width gears which should withstand 300hp. The 06 wrx even have stronger trannys supposodly.

I'm assuming you mean drag type racing. You would need a minimum VF30-34, all the good pipes, and the fuel and tuning to make it all work together to beat a stock STi. You also need to know how to drive, while supporting brake and suspension mods would help too.

That's a stock STi though. Once he mods, it's all out the window.

I dont know where you get this information from. But even the dealership confirmed that WRX tranny are the some from 02-05. The only difference is in the syncro (someone need to confirm this) for 04-05.

I'm not so sure about the 06 though

SOA is wrong all the time when it comes to that kind of information, just ask Jamie about H6 upgrades and break clips. The computer says the same clips for all WRX's if you look it up individually, but Jamie opened a 02 break kit box and an 05 break kit box (I believe) and they had different parts in them.

ej257 shortblock and supporting mods + ppg gearset and supporting mods + weight reduction = $$$$, but should be very fast in a strait line. Braking and cornering will be another exspensive formula.
