you have a single port. you will need the split port top end including the heads, intakes, and supporting fuel rail/injectors. i believe thats all. yes you can keep the same block.

the upper intake on a single port looks like a 5.0 upper intake and says 3.8L on it and the split port you can count the runners in the middle of it and is only on 99-04 mustangs.

have you thought about doing the m90 swap instead? youll get a little more hp, but tons more torque. from what i hear, its a much cheaper swap.

Re: single port or split port

by the time you do the swap you might as well buy the entire souper coupe engine, there are M112 03/04 cobra blower swaps out there pretty cheap for single or split port intakes (replaces them anyway) and they are getting GREAT results, much better than the M90 supercoupe

I'd stick with single port, port the heads and intakes, and be done.

yea but you gotta get a custom fit adapter and a whole mess of other custom parts. in the end that will equal out to getting a new/ slightly used procharger or vortech. the parts for the m90 can be found very cheap. i thought all you need for that is the intakes and fuel upgrades? dont you keep the heads and everything else?
