1998 GT

im thinkin about doin the pi swap on my 98 gt soon my question is what if i founda wrecked 99-04 mustang gt at a salvage yard and took the heads cams and intake from it? good or bbad idea? and i also heard that if u do the pi swap on the 96-98 gt use have to run premium gas b/c it raises the compression-is this true?

You can get the h/c/i off a wrecked car but I'd still have a machine shop look the heads over. I would recommend getting a tune and using 93 after the swap. You may try running 87, but it may detonate and you'd have to lower timing or run premium.

If you find a wrecked car then pull the entire motor and use it. PI SWAPs are for Babies mommas and for nitrous cars.

What?! [:@] Ha ha... You'd have to run 93 and get it tuned or else it'll be a ticking time bomb. I agree with sxynerd (well, some of it ), just swap the entire engine. Take it from someone who has done the PI swap.

screw entire motor! its called build the old motor from the bottom up and use the stock pi heads until you have money to port them :]

shoot, im making 260/290 with 9.3:1 CR(new built motor) where as i was making 270/310 with 10.5:1 CR before new motor.

but yeah you'd have to get it tuned soon and use premium gas of course for optimal performance.
