the r32 GTR is still classified as one of the quickest GTR's made, the orriginal godzilla, forget about the new GTR, these and the same 2.6ltr twin turbo motor in the heavier r33 and r34 GTR's runs in the 12's, give it as some people on here have said a better exhaust, wind the boost up a bit or bolt a large single turbo on and they'll easily run 12's all day and if lucky into the high 11's all day, one very strong motor along with the twin turbo supra motor, 500+ hp with just bolt ons and will do it all day, same as vl turbos, exhaust and wind the boost up a bit, easy 13's and some into the 12's with just bolt ons, that same nissan family of strong motors.
the ve v8 is a powerful motor as everyone knows, a few bolt ons and a good tune and you will give them a run for your money as stated in other posts, and as stated the GTR has weight and AWD on its side, plus 2 hair dryers.
its all a learning curve, who knows a couple of bolt ons, good tune, hit the track again and you might come up trumps, or alot closer anyway.
Good luck.
