98 1LE Z28 vs 20psi WRX so i raced a "built" wrx tonight it had a tune, upgraded turbo. full exhaust, bov, coil overs, bigger injectors...im not positive about all the mods thats why im being kind of vague, it was my friend driving his buddies wrx...my mods are in my sig and we did 2 highway pulls both from about 40, first run i started in 2nd and got the jump by 4th he was about 3-4 cars behind, second run i started in 3rd he pulled a half car off the third honk until he had to shift while i was climbing through 3rd then when i hit 4th he was probly 2 cars behind....from a dig we left off the horn, wrx bugged a little while i spun, as soon as i got traction in first i pulled right up to him hit 2nd and pulled right past and kept pullin...good kill for team ls1 tonight!!

Don't sound like he had the mods he said. WIth everything you listed he shoudl be over 400awhp. Enough to walk away pretty easy.
I love how its always a "BUILT" STI/EVO. Either all you guys don't know what a BUILT one is or they don't when they tell you its built.

Watch the WRX in this video and you see what a BUILT STI can do. This one had basically same mods as you mentioned.

I meant to say aren't, which of course makes the rest of my post make a whole. lot more sense. Point being that you can easily have a wrx with the above mods making low 300s where an sti would be in the high 300s+. Point being Ohioborn is wrong.

Depending on the generation of WRX, the WRX could have a 2.0l or 2.5l H4.
The WRX didn't get the 2.5l EJ255 until 2006 if I remember correctly.
And btw, the STI's EJ257 is more durable and slightly different from the EJ255 in the 2.5l WRX.
The shortblock is roughly the same, but the heads are revised and the pistons are slightly different.
Oh yeah, and the EJ255 has an open deck vs. the EJ257's semi-closed deck.
Also, from what I remember (could be wrong), the 2.0l WRX and their EJ205 is close to its limit over 300whp without a built bottom end.
The rods are a ticking time bomb around 300whp. Does a forged rotating assembly mean it's "built"? Many would argue, Yes...

Agrees with sujomatt. Its a popular upgrade for wrx guys and they always say bigger turbo too scare people off. Ive got a few good friends with wrx and the mods mentioned above and they are all 280-300awhp. They all think my car is a beast....even from a dig race they lose bad.
Nice kill!

WRX EJ205(2.0L tiny turbo)lighter than STi and different drivetrain,engine, and suspension but same chassis. The tranny usually breaks at 360+whp for those who go rotated turbo. Yes a vf39 is a bigger turbo for that engine but not big enough but its a easy cheap bolt on mod. Some guys go rotated turbo's which produce a lot of whp which is good cause of the weight but like I said if they don't do something about the tranny its pointless, its like walking around with a grenade and the pin pull and your hand gripped tightly and waiting for somebody to **** you off.

Think the Wrx got the 2.5 in 07, I have an 06 STi and i don't remember the wrx of the time having the same size motor. Before I had the Sti i had an 02 wrx bugeye, vf39 turbo swap, sti top mount so on and so forth tuned by PDX tuning, a stock ls1 f-body would still be able to pull on it without much effort especially from a roll. The Wrx gets a 5 speed the Sti's get 6 speeds unless thats changed with the newer hatchback body style.
Real quick edit: 20Psi on a vf39 is really pushing the limits on what that turbo can produce. This is all from my personal stand point though on what i experienced, take it as anything else on the internet with a grain of salt.
