Older Style '90 Throttle Body on a '92

[Nate355RS]

I acquired an older style 1990 NT throttle body to use on my 1992 tsi. I know 1990 was kind of an odd year, but will everything from my '92 TB swap over to the '90 TB?

The main reason I want to do this is because I'm always fighting boost leaks where my upper FMIC pipe bolts to the TB. I'd like to be able slip a coupler on it and have one less place to worry about a boost leak.

I use the 90 nt TB on my 95 so it should work on your 92 and love it I did the free fiav mod and port matched my intake. I also wanted to get rid of the elbow and of course have a 2.5" TB . I also swapped my tps and iac right over with no issue so you should be fine.

That's good to hear! Does yours have two or for vacuum ports? Mine only has two for some reason.

It has 3 ports that face toward the front of TB and I think 2 are only vac and the other I have capped off.

Just looked at my TB and I don't think it will work. I have the older style NT Throttle body and it doesn't look like there is anyway my 92 TPS will work on it. Looks like I'll have to convert to 1990 sensors or find a new TB.
