I running a JDM STI VF29 currently, with STI Pink Injectors, Cobb reflashed ECU for a VF34...etc...question is: Should I hold out to afford the VF34 or should drop in an 05 STI VF39? Is the 39 comparable to the 34(- the ball bearings)? Will it increase my horsepower? I can get teh 39 off a buddy for pretty cheap(<$400). The 29 is roughly pretty small but a lot of fun. If I had a 34 I should roughly be around 290 HP.

Also, Does anyone know if the 05 STI mirrors will fit an 02 WRX? Same paint color, just different scheme on it. Thanks.

 

if you can get it now, and cheaply, i'd put in the 39.

the difference between 30/34 and 39 is pretty subtle.

 

That's what I wanted to confirm. Thanks. I'll let you know how it goes once it's put in.
