Ok so far I have the following; 4.10 gears, Shift Kit, O/R X pipe, and Flows. Now I need your help and opinions. Should I stick with the 2 valve or should I drop something like a 5.4 in her or a Terminator motor? What would give me the best bang for the buck? If I stick with the Non-PIed motor I have now, I was thinking doing the PI swap, Cams, Nitrous, and headers, but I dont think that would be enough? Even if it was, I only heard the 2 valve motors can only handle around 400 or so HP? So I've been browsing around looking at other peoples SN95 GTs and seeing what there using. But I still dont have a clue. Should I just do a full engine swap? Help! I need some suggestions! Thanks guys!
