Ok so I bought another project car a 1996 nissan maxima 3.0l v6 approximately 190 hp. Car isn't that bad but it's reaching 200k miles and I'm tring to make 250+ hp. Ok well should I build the internals and tranny and try to boost it or swap out with the new VQ35DE that's like 265 hp I beleive. If I swap engine out I think I'll need the new tranny so that's bout 2500 on just engine and tranny so wat should I do?
