Mods, If you feel this needs to be move to the Nitrous forums, please do so.

I have had good luck with my paltry little stock 48mm TB, but as times change, I need some LT1 community help.

Seeing as that I have a 93 (odd ball I know) what does it take to replace it with a 94 - 97 TB? I know everyone list two different P/N's, one for the 93 and one for the later years. Car has cruise control and does not have traction control.

Is it just a change in the throttle linkage on the side or does it also have to do with the IAC passages? I think I can get away with changing to the TPIS IAC housing, and even upgrading to the 94 up IAC and flat 4 wires vs. the 93's square plug.

Reason for this proposed change is that I am looking at getting the Holley/NOS throttle body (has the integral dry N20 ports, the IAC passages are correct and its shinny:D )

I also found that Holley has a retrofit kit that makes there N20 kit legal in CA.

Thanks

Marc

Throttle bodies are the same the only difference is the IAC's and cable bracket.93s have the tv cable but since yours is manual it won't affect you.
