So I知 swapping a 94 1.8l engine into my 91. Since I値l be running it through my 1.6 wire harness with a MS2 is there any possibility of keeping the 94 throttle body since it already has a VTPS?
If so, is there a known connector I can use to wire into the 1.6 harness that will fit the 1.8 VTPS? Also will the 1.6 wire harness connector fit the 1.8l idle valve?
I壇 like to avoid swapping in the 1.6l TB with an adapter if I知 just going to have to find a VTPS to wire in anyway.

I'm sure you can find a connector and build what you need off of this site

The plug for the na8 throttle body is not listed in the ballenger table but it is the one for a jz throttle body.

If you are going to turbo I would suggest getting a NB throttle body. The idle valve doesn't need a separate hose back to before the throttle body. This way so it is a easier / cleaner install. The connectors for TPS and IAC are different than NA too, so if you are spending now, do it all now.
