Ok i'm guessing the y1 is cable tranny. You'll need a clutch from 90-91 integra. Same with aftermarket clutch. Now for the manifold. It is possible to put a type r on it but way too much work. Heres a much better way. Get a skunk2 manifold for the gsr
That place racing shift linkage might not be good. When i ordered one from them my third gear is my first. Both rods rubbed against each other. Lots of ppl had a problem with place racing shift linkage. I just went with hasport.
