300 HP goal is doable with the I6 turbo . Like i said , too much work to do a VGET swap and for a very little gain . The I6 is easier to work on than a V6 and you don't have to worry about doing timing belt every 60k . I would swap the Z31 computer system and turbo your I6 , that's my opinion . If you are going to do a swap then do a V8 swap , fab labor is about the same . I have an 84 turbo and a 91 NA , I hate working on them , especially the Z32 , the Z32 getting an LS soon . My LS conversion S30 and S130 are easier to work on .
