WHat car would be better for me if I wanted to build an import racer with a turbo? itr, gsr, or an rsx-s? I heard that a turbo doesn't go well with an R engine, is that true? I really wanted an itr but I just want to know which car would be better for me and street racing. thanks

First, what are you trying to get out of your car? Will it be a drag racer, an autocross car, a show car, or what? And of course, you'll be utilizing this additional power ONLY on the track, right? Cause thumbs down to street racing, as I'm sure many of the fellas/ladies here will agree with.
I haven't had personal experience with a turbocharged ITR, but I've heard from a number of guys who have that they're on their 3rd or 4th engine, so that doesn't speak of great reliability. If you spent the time and money for a standalone engine management system and properly tuned it and everything, your chances would be better of course.
As far as a GSR and RSX-S are concerned, the RSX starts out with more horsepower, but because it's newer, there are less kits available. Also, other things are to be considered, like the RSX's Macpherson strut suspension as opposed to the GSR's independent suspension, if that matters to you. Also insurance would be a bit higher on an RSX, because it's newer.

I suggest getting a gsr, because it sounds like you want to do drag. They are cheaper and will work better with turbo. The ITR is better for road racing and staying NA.

GSR

Yeah, GS-R definitely....
