1g throttle body -help-

i finally got the motor back together but the issue im having now is that my turbo throttle body is pretty much junk and im having a hard time finding a new one for a decent price, my question is that i got a 1g 4g63 n/t throttle body thats completly rebuilt. Is there any way i can get it to work?

Yes it can be made to work with a few modifications. I have an extra 90 turbo TB if your interested in just buying that. All you would have to do is put your TPS on it... Yours is a 90 right?

my car is a 92 but the engine is from a 1990 tsi awd, ecu is a 1992 fwd turbo ecu,

what mods do i got to make to make the NT TB work on my turbo manifold ?and how do i make the elbow fit, can you send me to a write up on this, or maybe some pic's would be great.

I think all you have to do is the EGR blockoff plate and block off some of the vaccum lines... I would just get a 90 degree elbow that will fit it instead of trying to modify the one you have. Also, what year is the n/t tb from? The 90 ones had a different TPS than other years. If the n/t tb is from a different year then you will need the TPS from that year (if its not already on it) and then hardwire it into your wiring harness. Sorry I don't have a writeup on it.

can you give me all the info you know on doing this, like all the things i need and what i will have to do to make this work, thanks man

Well what year is the n/t TB from and does it have its TPS on it still? I need to know that before I can tell you what you need to do.

You can't use a 1990 TB or TPS. The N/A TB are perfectly fine, you will have to live without a tb-elbow due to the lip on the n/a. The opening on the n/a is a little over 60mm though it tapers down to 60mm at the butterfly. The TPS, ISC are both the same between turbo & n/a cars. It is recomended to replace the tb seal on a n/a, you can find that on Vfaq.com.

To clarify, it depends on the wiring harness. The fact that you have a 90 motor is meaningless. A car with a 91-99 wiring harness can use 91-99 turbo TBs, and NT TBs, though I thought only the ones from the 2.0 are worth using. Can't guarantee that one from a 1.8 will work. The NT TBs require turbo TB shaft seals to be swapped in. I don't think that modifying the UICP to work with a NT TB is worth the time and effort at all, just swap the ISC and FIAV subassembly over assuming the basic TB itself is ok (plate or shaft is not bent, etc).

ok sweet thanks
