So. I'm almost done with my 63 swap into an 89 factory Mirage. The engine I swapped is a 6 bolt block with a 2g head. The sensors obviously wouldnt work with the 2g throttle body so I swapped out the 61 throttle body. When I went to boost leak test it before start up there was a massive boost leak underneath the throttle body. So, I took her apart and ordered a 90 turbo throttle body and oem gasket. It also leaks drastically from the same spot. The casting on the 90 throttle body has a relief in it like the 90 throttle body. So, I need exactly what I don't have I think.

I need a 91-94 throttle body and instructions on how to wire in the new sensors. It is the only one that will work with the 2g intake manifold. Anybody else have any suggestions?

Are you leaking out of the FIAV assembly?
