sti 3/4 inlet manifold
 

hi could antone tell me if a sti 3/4 inlet manifold will fit a 93 wrx?

physically yes, but the one you have is better

You will have to swap the pins around on the TPS, plus it does not have an idle switch on the TPS so the standard ecu will just continue to stall.... after market ecus such as the Apexi or Link do not use this. There are some other things to consider too and it depends on why you are thinking of changing... if its to use a front entry turbo then it makes the swap easier as you don't need spacers etc to get the turbo inlet under the old manifold.

As for which is outright best, depends what you are after. Personally i'd use the version 3/4 for a little more low down torque tho (longer runners)....
