Long story short. I need a bigger throttle body with TPS for a 1.7L setup that has 2.0 cylinders on it. I have 3 throttle bodies in the garage. a 1.7L, a Porsche 2.0 TB with plenum and runners, and a VW bus 2.0 without TPS on it. None of them are working for me.

What is it that's not working? Does it have 2l heads? If your all stock 1.7 except for the cyls, a stock 1.7 throttle body should work just fine. I know cause I drove one for 25 years.
