Actually, You've got that backwards, all Turbo I's are a draw thru up to '87, '88's and up use the same blow thru setup as the Turbo II's w/o the intercooler...........
Yep you are correct. 1988 and up all used the same intake manifold weather it had an intercooler or not. They also went to the cross drilled style cylinder head. That's why they quit cracking cylinder heads.
