Well as for which GTR is better I guess that depends on who you talk too. The R32 will always remain in the top of the ladder I think, more because of its history and of course its power to weight. Think the R32GTR weighed in at 1430kg, which made it awesome. And to have a engine that would make 500 hp in race trim with all wheel drive.There was nothing better, And its the car that gave us the name GODZILLA, thanks to the Australian motoring press. I could go on and on. Otherwise I guess it comes down to what ya want it for. I'd like a 33GTR simply because I prefer the inside look, bit more updated looking than the 32, and there are a couple of improvments on the 33 than the 32. But thats me. I,d like a 34 too but much out of my price range for that one. If your only going for something as a race car and dont care how it looks,32 for sure. As for your other question in which way to go with your car, Well I,d probably still just get a GTR, Seems alot less of a headache for ya. I understand about the power situation, but hey, I,ve heard people getting 800hp out of a RB26 without even touching the bottom end, was all just bolt on stuff. Thats pretty dam good I think. So either buy a GTR and wait till you have money again for the power that you want,OR keep yours and hope you wont have to get a loan just to finish the job of the fitment of the AWD system. Then you'll also have engineering certificates to think about. Hope this helps ya in some way.
