I want to put together a project car (1995 240sx) and get maximum horsepower. I have not purchased a motor yet. I am considering a SR20DET and would like to know what hp is possible if money is not an object. I have other mod's to do but am greatly concerned about maximizing the hp.

Also, I am new to the 240sx. My previous experience is with GM muscle cars. Can a v-6 fit in a 240 and is it practical.
