Hi

Im sure you already know but you will need an adapter plate to fit 20v itb on 16v head:





This one is ported to fit 16v small ports with 42mm St itb.

For the ecu I suggest you MegaSquirt even use as piggyback only.
A MS-1 PCB2.2 like this one can do the job easily...cheap too and can be tune for ANY others modifications like putting a Knock sensor on 16v ect.




For the loom use the 16v with 20v tps.
You will need AFM connector modifications to provide fuel delivery
You will also need to tap an AIT sensor in one itb to provide perfect air temp reading (Place it near the port that will provide perfect reading) I suggest you use a GM AIT sensor(2 wires) if you decide to go with MS.

Also the harness can be connected directly to a ecu like the MS if you do it or buy it from me this kind of plug-and-play adapter:


(Made for Tom Ae111 to plug and play stock harness 20v blacktop with EDIS4 attached)

Im not sure you really want to invest at this point but I suggest you to buy a complete blacktop with harness. Take the itb with tps, sell the head, you can get a good price for the head setup you can also sell your 16v block!!...
Use the 20v block with 16v red-top PORTED head to get the maximum air entry offer by the itb . Cams 9mm+ lift, shims underbuckets,springs and have fun.


Good luck with your project
