Intake
 

Will the intake manifold, air horn thing off the 2nd gen fit the 1st Gen trucks? If it is a hood clearance problem, that is not a problem.

ive never actually tryed it but the heater grid is the same so the 4 bolt pattern has to be the same. the hood shouldnt be a problem even if it is stock. i dont know about clearance around the injector lines and brake master cylinder, ect. i see u have a 93 so it should already be intercooled which means the intake enters in the front half of the head, that should help. i would say u can probly make somethin that flows even better than that thing, but maby not as cheap as a used take off. ive been lookin in to what it would take to use 3" piping and maby even have a dual feed intake with 2 heater grids and all. im convinced that for a turned up daily driver we need significantly more flow at low boost than what the stock heater grid can flow.

Yes it will work for you. Or you could get some of Tim Worlines' stainless coolertubz and put on there they really look great. He is on 1stgen.org
