I put a PI intake on my car back in the fall, and ive been reading up lately on the PI intake and many people/places are saying i HAVE to have the PI heads. Is this true, and how easy/how much would it be to swap those out if i must put them on?
 
You can use a PI intake on non-PI heads. If you're running N/A, you could just as easily run a thick bead or RTV around all of the ports to ensure their seal. The '96-'98 guys as well as the T-Bird/Cougar guys have been doing this for a while now with great results. If forced induction is in your future, I'd suggest buying a set of adapter plates. Livernois sells them with their intake kit, but I've seen the on Ebay advertised before for less.

take a look at my plates and web site.
www.unitedmajority.com
you can do this install for 1/2 the price of the livernois kit.
you can use your existing hardware, a new PI manifold with the alum. crossover $160-$192, gaskets and my plates to blend the ports.
many here have done it. I have 7 sets left then thats it.
I am running a PI manifold, plates and a vortech and its working great.
 
If your car is 99+ yes you have the PI intake and heads already. The 96-98 cars are the ones that were so lucky to get the crappy flowing intake and heads. There is a misconception with some newer (99-04) Mustang owners that the PI intake is an upgrade...these years already have the PI stuff.

am i reading this right, you already have a pi intake installed on non pi heads? If i'm reading it right then you answered your own question by doing it without pi heads.

you can add the pi cams for a nice gain without the expense of buying the pi heads.
 
Yes you are correct i swapped the Intake a while back but i was just concerned after reading up more on this. Mainly ive been reading up lately because i have been contemplating doing the PI head swap, or possibly doing a head swap and a Cam swap. If i do what would these require/how much? Anyone have numbers?

do the head swap and add some VT stage I cams. you might as well do the cam swap while you have the motor apart.

do some research at www.modulardepot.com or www.modularpowerhouse.com

:stupid: if your gonna take the time to swap the heads, vt stage 1 is a good cam to go with...get some springs too while your in there. maybe even go with a ported and polished pi head set if you can afford it! i'd estimate a p&p'd head with vt stage 1 at another 40-50 hp. definately worth it.
