ok this is a little far fetched but it was a while back and i cant remember where i saw it but i seen a page with conversion tips for the 87 prelude.
it included modifications to the tail lights, integra suspension conversion, b16 intake manifold conversion, and a few more things i cannot remember. for all the good people in the forums please help me find this page. if it helps the pictures were hosted through imagestation.

your best bet would be to find the 3rd gen prelude heaven page, search around on this forum in the archives, and see what you find, 3rd gen info is limited, but people have done stuff
