INLET MANIFOLD of GSI

As the tittle said, i know the GSI inlet manifold is different to VTIRs one, but it looks the same as the Type-R and B16A ones...so what is the different with it?

i have my 95 GSI with a TypeR throttle body fitted straight on it , but i forgot to measure the size of the original and the type R one...how big is the difference?

inlet ( throttle body) size is smaller than the ITR , and internally it probably will be smaller too. anything else though i can say.

Different sensors / location too.

Wait until a pro replies with the facts :)

thx ben

but i think most ppl with GSI either go with turbo or vtec conv...
not too many spending time and money on the B18B..am i right?
