Quick!! Question on swapping throttle body('90-->'91)

EclipseXstacy · May 16, 2002

I just did a perusing of vfaq.com, but can't find the answer and it is getting late so I'll make this quick.

I found a good deal on a throttle body today, and if everything goes well then... It came from a 90 turbo FWD. My car is a 91 turbo AWD. Now I know the TPS on 90 and 91-94 are different, so what do you think..will the WHOLE throttle body swap work?
*yawn* good night.

The ISC is different too from what I recall. Also the vaccum routing is too. So if you find a way to rewire it correctly and cap off some unused vaccum lines it could work. Try and check RRE for info on this throttle body swap on a 2G. You might find something helpful on the 90 TB.

The shape of the isc motor is different depending on the Size of the motor (1.8L vs 2.0) for all 1g.

So I think my isc connector will fit that isc motor quite fine. My primary concern is if the TPS connector will fit that new one b/c the configurations are different for 90 and 91 TPS. Also like you said, the vaccuum nipples are 2 on top and 2 on the right side, as opposed to all 4 being on top for in 91 so...

So are the ISC motor the same between all 90-99 dsm's? Since there are many who needs to replace them....?
