I found a 93 turbo intake. It looks identicle to mine ( 95 ) and I was looking to polish an intake , until I my custom intake made. I have the upper done and ported, and wanted to polish and port the lower to match. Are there any things that changes for the years ?

All head port patterns identical, but '92-93 upper has no IAT or MAP.

EGR version is easily identifiable

So I can use the bottom , with my already polished and ported upper for the time being.
