Let's say you do PI swap on 04 GT mustang. Does the PI GT engine resemble 01 cobra engine then or are there differences between the two motors still?

i was wondering if i did the PI swap would i be able to supercharger??? i know the PI swap runs the compretion up to 10----something. is that too high or should i just do a supecharger and cams????

If you stick with 8lbs of boost you should be fine (from what I hear). That's actually what I'll be doing on mine.

I ran that setup for about a year (PI swap+S/C) probably should get a meth kit if you want to run a fair amount of timing

You know what I say? Screw that! You're going to spend, what, around a grand on the PI swap? You could pay a good amount on some Stage 2 cams with that price and you'll see the same HP gains without the added worry of compression. That's what I'm doing. I'm supercharging my 97 GT and then later I will P/P my heads and put some blower cams on there. It costs more, but I can safely run whatever amount of boost my internals can take because my compression is VERY blower friendly
