well are you asking what's the part differences or what a pi swap would do to a non pi engine? honestly i don't know what gets swapped i've only helped a friend on the last part of his after the upper intake and plenum were installed (i basically just installed his chip and helped finish loose ends)...i know the basic premis is to see nice hp and tq gains due to a compression difference in the non pi motor. From what i can tell on his car it was worth the swap because when i had my '04 GT with minor bolt ons he'd leave me behind with just an exhaust and the swap done.

a pi swap..you know new gaskets and solid parts are going into your motor...besides you'll have a nice bit more power over a standard pi motor

i think it's close between a 20-30 hp difference over a standard pi motor if i recall the last guy online to do a swap.

Hmm...what's the pi swap cost? I've got a guy with a manifold, cams, and heads for 550. Are there better deals out there? What else do I need?

Mps has them 849+shipping for whole kit. Is this a difficult diy project? Should I just take it straight to my shop? And if so, what would that bill look like?

first question do you have a way to tune it when you're done? it's good to think about all the little costs to make a pi swap work 100% like that

I never needed a tune on a pi swap. Only tune uses for intake mild cams lts and so forth. Pi is just put it and done if ur gettin all the pi stuff stock
