so i got everything out of a 86 turbo coupe... engine... wireing... trans... what will i need to do to get this to work in my 92 mustang? do i have to change all the wireing under the dsah and all? or just the engine part of it? i got the computer thing that goes in the side kick panel... anything else i need? oh and the best part is the block is a .30 over forged piston ranger motor...
Will have to repin wires at the computer. Stinger site has info but the 86 vam wiring is differant. Sleeperinc and me went thru this on his. He made a tech article on the differance. The small vam on the 86 is differant the the 87/88 turbocoupe. No dash modification it is all in the computer harness. Basically swap the motor, redo exhaust, mount vam and hose and drive. Using the mustang motor mounts, Some of the na parts will need swaped over. I reused Mustang ac, power steering and Alternator just remounted. Picture of my 89 with 86 motor Next step I intercooler it. Can leave vam mounted like in turbocoupe. Just put K&N on end. More pictures in my photobucket or ask for more.

The small vam is wire differant than a large vam. Here is link. The article name is p series computer into a 88 to 90. Just look at Stinger site and change the wire pins to this article where it mention vam. Then can use your p series computer. Second opion is find a big vam and 87-88 computer. Near as can remember the 86 is good for 145hp the 87-88 computer will get you about 175. Or more with cold air intake, good exhaust and intercooler. Still use all your motor as is and repin per Stinger. Your option if need more info just ask.

Here it is for you
Wiring a P series VAM into a 88-90 Mustang (this is for when your doing a 2.3 turbo swap with a computer other than a LA, LB, 8UA series)
Splice into/”T’’ connect the VRef (orange/white) to the wire going to pin 26 of the stock harness (also orange/white). (I say splice into/”T” connect the wire running into the engine bay. This is because pin 26 is being used by the TPS, MAP, and EGR.)
Remove Pin Connector #3 from LX wire harness red block (or take one from your harness you salvaged, and put this pin connector and wire into the red block of your LX harness to plug into your Pin 43 position on the P series computer. The LX harness lacks this connecting pin).
Connect the VAF (white/black) to the wire going to pin 43 of the stock harness (the new connecting pin you just put in)
Connect the VAT (vain air temp) to pin connector #27 (this can be found at your EGR Valve position sensor) Now move that pin #27 to pin #25 and move #25 to an area with no pin (this is the ACT sensor which only the PE, and 87-88 turbo coupe computers can use)
Splice into/"T" connect the VAM signal return (black/white) wire into the LX harness (black/white) wire that goes to pin 46. Do not cut the LX harness (black/white) wire going into pin 46, simply connect this VAM signal return black/white wire to it.
