i've read the write ups and all, so i'm pretty sure I can deal with all the vaccuum related items on the stock mani and make them work with an ITB set up. obviously a plenum would be needed, but my question is waht about the TPS? it has two plugs in it AFAIK, one for throttle, one for IAC, i've been looking at my engine, don't see a way around it, but I can't really mess with anything cause i need to drive the car daily, any input or suggestions guy? thanks in advance

Modify it to fit the throttle bracket for the ITBs. Then just get out a multimeter and properly calibrate it. You may also be able to modify the TPS that actually came stock on the set of ITBs to give the correct signal voltage to the ECU.

I have an extra KA manifold laying around here that I was thinking about cutting, welding ITBs to, and building a plenum.
