I have a WRX with ALOT of mods coming. I am wondering, even with all the modifications that are on the WRX, will the top speed still be the same because of the 5 speed tranny?

In a nutshell - Yes.

Assuming you use the Ecutek to remove the speed limiter first, you can push the engine through the roof in terms of power, but the car will always be limited to transmission gearing and final drive. FOr more speed, look to your gearbox and diffs for ratio changes. Of course, two things jump to mind:

1) A minimally-modded WRX will easily break triple-digit speeds...WHERE do you intend to use or need that much speed? (Power I understand, from an acceleration standpoint....but speed?)

2) With no suspension or aerodynamic mods listed, you'll lose grip and control far sooner than you'll hit top speed as limited by gearing anyway.

Good luck either way.

I didn't see any braking mods listed either....my stock pads were fading heavily at the track and I have a lot (a lot) less power than you.

have you only modded the engine, or did you not include Aero/suspension/braking???

 

EIBACK PRO SPRINGS, and a wing.

 

Is there anything that WON'T break "triple-digit" speeds? A fullsize stock Outback wagon will do over 100. A stock WRX sedan can do about 140.

 

my next mod is changing the springs, I was gonna get eibach...how are they???? how much do they drop the car???

 

utec, ecutek, and an mbc . . . why? don't take this the wrong way, but I think you need to do some more research.

 

i'm still bone stock in a rex and i can hit 135 with out any problems. now in a track setting i won't hit it first but i can still get there.

 

with all those upgrades a tranny should be on the list unless you like shattering gears...

 

What type of tranny do you suggest?

What is wrong with a utec, ecutek, and an mbc?

I am new to this. I bought the car with all the things mentioned allready on the vehicle.

 

utec and ecutek is redundant, and mbc is just something you don't want. i hope you have gauges, too. just browse around the EM and WRX Engine forums. brake and suspension mods are a must when you have extensive engine work.

 

hmmmm.. i didnt know they had speed limiter... becuz i have hit 135 as well... and preaty much knowin that it will go more.. i just dont have the space to do it.... if there is a speed limiter, what speed does it exactly cut out at..

 

there's no limiter.

 

There's a redline limiter I'm sure, isn't there? BTW, I've reached 140mph in mine.
