So we're talking about 375-400 HP w/ mods
with 25% more displacement, better injectors, intake manifold....it doesn't take a rocket scientist to easily envision 350-400 HP with
not too exotic mods like exhaust, intake, aggressive maps and race gas.......welcome to the new generation. This car might be able to play with Z-06's if the understeer is correctable. Wm

I'm still going with a stock WRX. With Vishnu stage 2 you can already have 350HP for about $5,800 installed and tuned. Plus he's got stage 3 almost ready (February 2003) which will produce 500HP on the stock tranny. http://www.vishnutuning.com/stage.htm

duuuuude! Imagine the new STi with just an ECUtek re-flash (lets hope SOA did not change the ECU encryption/code structure), intake and exhaust, I am pretty sure the STI will gain @ least 70HP. SAFE!!!

Good luck. Tuning is going to be trouble unless it has a forged crank. Ask the 2.5RS-T guys.

Call me stupid, but if I have the STi, I stay close to stock and use it as a daily driver, and mod my RS to hell.

It sounds like Subaru has beefed everything up as far as engine internals go... although, the 6-speed it still only rated to 300hp, so it may have the same issue with mods as the WRX tranny.

Well think on this for a moment... You will be able to get these things and drop them in your WRX or whatever. Trannies too. So if you have a WRX drop the motor in, go to aftermarket engine management and you have a lot of motor....

I was waiting for the first "mod" thread. You kids are hittin' the pipe. People on this board would want to mod the space shuttle. Let me guess. The STi is "watered down," so everybody wants to mod it, to give it the horsepower it should have.
Stop, you're killing me! Kevin |

The basic rule is: It can never accelerate or stop fast enough.

amen brother! if simple mods on a 227hp wrx can net 300+ easily just imagine with some normal boltons what an sti can net.
the sti is more than just the 300hp don't forget! controllable diff, standard hid lights, brembo brakes (thats 2k easily on the brakes alone) standard forged 17's with REAL tires (no sdkjff'n re92) and the list goes on. if i could afford a 35k car i'd want one. as my 24k car is enough to swallow i'll stick to my "base" wrx with a few mods. whoever owns this car will have quite a performer. i'm glad subaru didn't punk out on bringing this car over. they brought it full on, non watered down like we usually get from every manufacturer. even comes with a 2.5! heh sweeeeet. i would love to drive one one day. i'll pay off my wrx and buy a legacy b4 5 years from now Quote:

I wouldn't mod it for a while. The warranty is too valuable to me.
After a few years now.... |

I doubt they're pushing above 18psi for those figures. It would be interesting to see what turbocharger they are using and if the intercooler is the same size and design as the JDM spec models.
If I were to get one, I'd like to be able to push it to around 350 or so hp, and I am sure most of that can be done with mere breathing changes and an updated ECU. I would probably have to add the 3" STi Cat-Back just for the stealth look. Perhaps a tuned header, downpipe with high-flow cat and upgraded STi panel filter and hoses would be added. That should decrease any apparent lag (if there is any) to nothing, while increasing engine efficiency and power at the same time. I don't think that's going too far. (I hope the factory turbo can handle that, I'd rather keep the factory turbo.) But then again I can't afford an STi for a few years so I'll just keep dreaming. (I wouldn't mod the Space Shuttle either, I'd just build a better one. ) Last edited by SUBE555; 01-07-2003 at 11:14 AM. |

When or if I buy my STi, hopefully TurboXs will have there UTEC set up for the STi, so ill buy that, a turbo back exhaust, and an extra pair of wheels and tires.
