Hey are the Newer PI heads the same size as the ones on my 98? i know there close but just wanted to know if they are exact, i have to mock up headers and i want to get a start on it before i get new heads

14psi, via twins will blow that motor all over the ground before the chunks from a cheap turbo will even have a chance to get to it. Especially with the ADDED compression from the PI swap.... close to 11:1 + 14 psi, your going to need straight race fuel, or E-85. 4:30 gears with a turbo will not do anything... 3.27s maybe 3.55's is what you want...

Physically yes, but from the sounds of what your wanting to do some of your questions are alarming as far as knowledge goes.

Okay well i called over to the junkyard today and it looks like im taking the heads off of an 2003 crown vic. Im paying 130 for each head as well as a 20 dollar core charge. What are some exact tools that i would need to pull those heads off and what should i keep when i get them? I planned on just keeping the cams/springs/valve assembly and pitch everything else?

You should most likely just stop the build for right now and search the forum a bit on how everything works with the 4.6l motor... there is a lot more to it than just throwing on parts and hoping they work. There are some great articles on this forum about how to choose what you want to go with and how to do it. Most of us on this forum have tested things and given our .02 about how we feel it went. Read up on them and you will change your way of thinking real quick, but just to get you started here is a link that you should read before you do the swap.. https://mustangforums.com/forum/4-6l...d-to-know.html Good luck!

Thanks for the link i have a feeling it going to be very helpful. Ill try to post some picture as i go to keep you guys updated. Im going to get my heads on friday and im pulling my stang in tomorrow to start to pull the motor/trans. The guy before me put the wrong throwout bearing (off a V6) in and i have to fix is loud squeeky mistake.

very interesting given all throw out bearing are the same for V6 and GT. I'm excited I imagine some quality post coming from you in the near future
