2003 mustang gt turbo swap, need some help.

Hey guys i need some help figuring out what should i upgrade when i get my T70 turbo in. For example should i do a pi heads and pi manifold swap, should i port them? What size and what brand of throttle body and plenum should i get? Just things you think i should up grade. So far i have a stage 2 clutch, 3.73 gears, x pipe with flowmasters, short shifter, steeda intake i think thats it. thank you so much for your help.

I'd get a 75mm TB and plenum (accufab TB and C&L plenum best) and definitely port the heads, but concentrate more porting on the exhaust side and don't overdo it. Having the professionally done by a good modular head shop is the way to go, it's easy to screw up the porting and get left with a cool looking boat anchor. As far as PI or not, depends on what boost levels you plan on and if you're gonna intercool, the PI swap will raise your compression and that may not be good.
