98 pi head swap

98gtvertmason · May 13th, 2011, 05:12 PM

i have the stock non pi motor in my 98 gt (automatic

) and i recently found a set of pi heads that come for the 99-04 gt's. it says they will fit my car year but it increases my compression ratio to 10:1. do i need to buy any kind of new pistons for that or can i keep my stock ones?

If you are not planning on adding a supercharger anytime soon then your stock internals will work fine with the pi heads. Part of the extra power you get from a pi swap comes from the compression bump.

there no point of making this thread about pi head cam swap cause know will post... the best thing to do is use the search button.

98gtvertmason · May 16th, 2011, 06:03 PM

pretty sure it says head swap... no cam no intake in the title. thanks for the useless reply

97S281 · May 16th, 2011, 06:27 PM

Well, you should consider using at least the pi intake along with the pi heads. You will gain alot more power using the pi intake as well.

You can keep the stock pistons.

ahh nah man i wasnt meaning that to you lol your reply was actually helpfull. thanks

whiteboy05 · May 18th, 2011, 12:08 PM

Im pretty sure i didnt say anything about pi intake swap. And when you do a head swap your still gonna have to mess with the cams

these heads come fully assembled with cams valve springs and all. guess i shoulda mentioned that

If everybody used the search button there would be no new threads. I'm pretty sure every mustang issue has been discussed on here at one point in time. No need to give the guy lip for trying to learn something new. And to answer your question your stock pistons will be fine. Good luck with your build!

thanks man! im sure he feels real big and bad for giving a 17 year old lip too...

white is correct - there are tons of threads that couldve answered your question for you without you starting a new thread.

i do believe he couldve worded it a little nicer, however.

that being said - both of you please take it to pm's.
