PI engine VS PI swap

[tank_567]

Well today my brother installed my old ported pi swap engine into his 98 v6 mustang. We dyno'd the car with no other bolt ons, just ported heads and a tune. The car made 255rwhp and 301rwtq! My stock PI engine made 230rwhp/264rwtq. I'm making only 15 more hp than that with full bolt-ons and a tune. I guess doing a pi swap is better than buying a pi engine/car. What do you guys think?

lol, I just noticed our old 98's made the same hp!

an increase in compression helps the numbers a little on the PI parts swap.

the pi swapped npi engine makes like 240-245 wheel hp with the bump in compression...hes got a tune and some ported heads.

Thats where the 255 comes from

Yes a pi swapped engine will make 10-15 more hp than a pi engine.
