Another drawback to the Evo's are that they heat up like an oven.. I have had some Evo owners I know complain about heat and cooling issues... Don't know if they're just stupid, or if it's a common thing... but that's just what i've heard about em

 

All times assume a good driver:

Stock '02-'05 WRXs run low 14's
Stock '06-'07 WRXs can dip into high 13's.
Stock '08+ WRX (I have no idea. They're too ugly to pay attention)

TBE with tune ($1,000-$1,500) '02-05 WRXs will run high 13's
TBE with tune ($1,000-$1,500) '06-'07 WRXs will touch mid 13's

STI Turbo Swap, TBE with tune ($1,500-$2,000 total investment) '02-'05 WRXs will run low to mid 13's
STI Turbo Swap, TBE with tune ($1,500-$2,000 total investment) '06-'07 WRXs can dip into the 12s but likely break their tranny in the process

I've had both an '02 WRX Wagon and an '06 WRX wagon. On the '06 I put an STI (VF-39) Turbo, STI TMIC, Cobb Catless DP, Borla Hush CBE, Custom Tune and made 304 AWHP. I ran 12.9s all day long. It was nasty from a launch, but I was scared to death of my tranny. The car ended up getting totalled, but I knew that tranny's days were numbered and would have had to swap it with an STI 6-speed eventually. Then you're looking at $3,000 to $4,000 grand plus installation. They're cheap to modify and make fast, but the trannys are glass.

 

Did you not have to upgrade the injectors or fuel pump to hit 304 on your '06? I had an 04 WRX with basically the same mods but it also had STi pinks and a Walbro. TurboXS tuned it and it made 284whp.

I'm just curious if the newer gen WRXs have a more supportive fuel system... I haven't really kept up with the Subaru community since I sold my STi.

 

The '06-'07 WRX injectors flow better than STI pinks. The fuel pump is mainly an insurance buy and not required. Had the car not been totalled thpough, I was headed in that direction for the fuel pump as it's pretty cheap insurance.

 

Cool, well I think it's a good idea you got out of the Subaru modding game..take it from me, modding them is a slippery slope once you get going ha ha. Do a search for me on NASIOC and you can see how far I took it with my STi :P

 

cool good info robert, so till they get pretty heavily modified theres that chance that we have em

 

Don't listed to him... Tranceformed Suburu was slow...

 

Hehehe

 

but a swapped GC impreza... thats something you have to worry about!
