So I'm working on getting a 3rd motor in the car but I wanted to ask before hand what are ways I can prevent spinning rod bearings. I currently have a gen v blower, n* throttle body, overkill pcm, colder tstat, 4in air intake.

Besides keeping the lead foot off the pedal, what else can I do? Is there any mods I can do before I slap the other motor in? And what year motors can fit in my 00 gtp. Can I fit a 04+ motor without mods?
