Got some 1g parts now some questions

[Race94]

Well i got a 90 TSI AWD throttle body, intake manifold, ported head with 2 angle valve work on valves.

Now for the questions:
How hard will it be to replace these parts on my 7-bolt GST? like do i need to modify anything and such.

If i replace the intake mani and throttle, what UICP can i get??

Thanks

the throtal body is junk, pitch it. If it does not have the 4 vacum lines on top its not going to work.

has pretty much what you want to do.

The throttle body will work... I know, because I am currently using one on my car... Just get someone who's done the swap before and you'll be fine... Road race's guide only shows you how to use a 2G CAS if I remember right. It is possible to use a 1G CAS, but it throws CEL sometimes... Magnus has a fix for that on their website. Other than that the 1G will bolt straight up and only require splicing like three wires... You're gonna need a 90 water neck and other things that you won't think of before you start bolting things together... Have fun!

a water neck?

shouldnt effect the uicp, its at the same spot, it might be slightly different, but theres quite a bit of play because of the silicon connectors

I asked RRE once why the early 90 TB didn't work and they said it had to do with the TPS bolt pattern being different? Then they said that it could be done with alot of rewiring but it wasn't worth the hassle. I never really understood what they meant. How a bolt pattern would effect electrical wiring?

I don't really know either... no problems here!
