91-94 Turbo Throttle Body on 90 GSX

[GSXlaunch]

I tried using the search function but found nothing useful...except a lot of information on how crappy the 90 t-bodies are. Anyhow, is there a write-up or can someone chime in and tell me what exactly is involved in going to a 91-94 throttle body on my 90 GSX? Comparing the two, they seem very different. Thanks

I'm using 91 GVR4 TB which I think it is same as DSM 91-94 TB ... I just used the GVR4 TPS with its plug and put a new gasket.

As for the throttle bodies the 90 tps and fast idle connectors are completely different then the 91-94's (at least mine is). 4WD-Eclipse, did you have to splice in any wires? Those pansies at slow boy racing told me the magnus would work just fine with my tb. How those guys are even in business is beyond me. Thanks for the response(s).

If I need to...anyone know of a good place to get a decent aftermarket thottle body?
