90 throttle body on a 2G?

[donmagicjuan]

I recently attempted to buy a 91-94 tb on ebay, but the item turned out to be a 90 (stupid deceptive description ). I was just wondering if anyone has actually successfully installed a 90 tb on a 2G, and if so, what mods are necessary to complete it.

I do know the tps sensor is different. Other than that i haven't messed with a lot of 2GS. i Have a 90 motor with a 93 throttle body and a 2g elbow. Elbow bigger on 2gs and 90 tps sensor different.

Do you happen to know if a TPS from a 91-94 would bolt up to the 90?

That I don't but I didn't mess with it I just used my 93 throttle body. I know there will be cutting of wires.

Aside from the TPS, I was also wondering if anyone knew how to resolve the issue of the missing vacuum ports on the 90 tb, and if the ISC was still the same.

Mine i just plugged off the holes on the throttle body.

Right, but my problem is the reverse. I have more lines than ports.

How many lines come out of the 2g throttle body?

The tps and isc are not the same style therefore you won't be able to run it....i have one laying around here.

There are 3 vacuum lines on the 2G, and only 1 on this one that I got. Just to be clear, is there any possible way to rig this thing up to work? The seller claims that "with the proper modifications" I can use it on my car. If he's wrong I'd really like my money back.

You cannot use it.
