Can I Put a 91 head/99 intake manifold on 88 Remax

I agree it would be a heck of an improvement. I think with some creative TIG work, you could make it happen. If you are in any other western state, you probably wouldn't even need to swap it, as the EGR really doesn't help all that much in tailpipe emissions during a smog test (I've smogged my rig with an inoperable EGR and it did very well). However the visual test would never fly in Cali. In fact, last time they tested my EGR ot make sure it worked by applying vaccuum. The engine died, meaning it was working.

That part of the Renix manifold is kind of complex, so you'd have to cut out a 3x3 section or so to get the boss, the threaded portions, and the EGR passage.

The smog rules really suck. I'm sure the late model intake wouldn't pass because of the visual even if it was fitted with all the original smog equipment and passed with flying colors at the tail pipe. Who knows this for sure? Isn't Bryan C the resident guru on CA smog equipment/issues?

How are you planning to adapt the EGR tube to the 99 intake manifold?

There are no provisions for an EGR in the 99 manifold.......

Not knowing the ins and outs of EGR I have one question...

Could you machine a throttle body spacer with provisions for an EGR tube?
