Turbo on Spec V...?
Im guessing a sentra spec v? if so I would'nt turbo it. We have a few here in Orlando and they just dont seem to be doing that well. They will beat up on the ricers but welly who dont. My opinion would be a VQ35de swap with minor bolt-on you will be a high 12 sec car, then the VQ loves nitrous. JMO
