Ok i'm looking to mod the 2.5 rs . I was thinkin about turbocharging it. Would it be like the STI? I mean they're both 2.5 ltr motors? I mean shit its the cheapest way i can think of instead of spending 30 plus grand on an sti and still cheaper than the wrx. I dont know the cr difference on rs and the sti but i'm pretty sure its a nice set up if i get the turbo kits for them. Please tell me how much the kit goes for on the 2.5 rs. I'd like to hear everyones' opinions on this set up. Thanks :)

RS motor is is very different from the USDM STi motor.

Have to get new pistons, rods, and cam i would believe that could handle a decent amount of boost. I don't know much about the RS motors but i wouldn't think it would nearly be as good as the STi 2.5 since the WRX STi is the racing version of the impreza.

dont forget the suspension differences...

Thanks for the info. OF course i know the suspension is different and kinda got the idea on the motors. I just checked the FAQ and i'm pretty impressed with the infos. Thanks again :)
