The complete engine swap i think will be the easiest route. They are the same engine, only difference is the intake and the cr, but i think the 300zx motor will be built a little better for power than trying to change around the stuff in my current engine. Also, i can leave the turbo engine out and put some parts on it while still having my other engine in the car to drive around for a while. Basically all i need to do to get that engine in, from what i hear, is take off the fan for the radiator since it was an engine for a rwd car, then it should fit in the car. Then i need to get exhaust pipes run all of the way back and get the turbo piping made and that should be it for the engine. I'll need to throw in a TTZ fuel pump to supply the engine with the needed fuel and that should be it until i beef up the tranny to pull some more hp. From what i hear, the stock clutch will handle about 300hp or so. I will probably just upgrade to the ACT or JWT clutch pretty soon.
