heres the parts list:
-97+ f-150 V6 heads or 99+ mustang v6 heads (including valves/springs)
-97+ f-150 v6 lower intake, or 99+ v6 mustang lower intake *
-99+ mustang v6 upper intake **
-99+ mustang EGR tube and valve (f-150 tube will work)
-99+ Throttle Body
-TPS sensor for TB (1-CX-1488 from Ford) if not already on TB
-Throttle cable from 99+ mustang v6
-Modified fuel rail that has a universal fuel pressure regulator, and a return line. (available from SteveC) ***
-Accelerator Bracket (F4SZ-9728-B) if not already included on upper intake
-99+ mustang v6 coil pack and wires (your stock coil pack will work too)
-99+ mustang intake tube, or any 99+ mustang CAI kit
-99+ mustang cooling hoses (including the ones going to the heater core) and pipes. You can also make your own lines, by using plumbing elbows,hoses and clamps, and fab it up yourself. (Definately get these if you can.)
-16 a.w.g automotive electrical wire
-teflon tape, pipe sealant, RTV
-99+ head bolts/studs
-head gaskets (I recommend 99+ mustang gaskets)
-99+ upper and lower intake manifold gaskets.
-99+TB gasket
-94-98 IAC gasket
-94-98 valve cover gaskets(reuse the 94-98 valve covers, valve cover gaskets can be reused if removed carefully)
-94-98 exhaust header/manifold gaskets
-you can reuse the 94-98 headers ****
-use the 94-98 IAC since the 99+ IAC has a different connector (Edit: I found that the IAC I used from a 99 mustang had the SAME connector. I am not sure about other years or F150's/windstarts, but the 99 IAC will work and I recommend using it for a cleaner looking install.)
-rad fluid, oil, filter, new spark plugs
-gasket remover, thinner to prep parts before applying new gaskets
parts list taken from the writeup over on 3.8 mustang, great write up
Sixpackstang's Official Split Port Swap Post - 3.8 Mustang Message Board
That is as complete of a list as I have come across. The swap should be completed by someone with at least a decent knowledge of engines, not someone who knows how to change oil... I would be hesitant to do this swap myself and I am fairly confident in my abilities but this is the list.
What do I need for a split port intke swap ?
