I ve just bought a 97GT conv also and just ordered the big mean Fr500's you all speak of the PI business but what does it cost to do it?

HpOoRwSeEr

well, depending on if you get the parts used, or new, and whether you do it yourself or pay someone. anywhere from $800 - $3,000

I did a PI Swap

PI Swap and Gear, you'll be happy, and yes, I know, I don't have a gear already, and I know he's looking for "hp", but a gear will make your butt feel happy, hehe

Id be a little disappointed if I were you....P/P Pi heads and you only ran a 14.4?

In my opinion... You should do full exhaust... make that mustang sound mean as hell. plus you will get a little hp gain... most likely around 10-20hp if you do headers/midpipe.

ummm, how so? I'm a vert auto with a slippin trans. With the PI Swap, Chip (not professionally tuned), and h pipe it took off .8 off the 1/4 mile. I ran a constant 15.2/15.3 before hand. Once I get it professionally tuned, and get a new trans, I'll be running better. But I'm actually very happy with the results. What, you think a PI Swap is gonna give 2 sec in the 1/4?

I would go full exhaust first IMO so I vote headers. The CAI will do next to nothing.(Nice car BTW)

I actually am taking a different route and getting my NONPI heads ported and polished and keeping them. I want to be different of course.

when you P&P NPI heads isnt that the same thing as having PI heads? i thought so, somebody please correct me if im wrong..

JonBeast

Did I say that? No

I'm not trying to be mean, but you can get a nonPI to run mid 14s. I would expect a PI swapped GT to run low 14s to high 13s. But like you said, you have a vert auto. Once you get everything tuned and the trans going, you should get some better times. Good luck man, make us SN's proud
