I need to know if a 88 plenum will work on my 90. I think 88 has the cold start injector....mine dont, so will it work? what will i have to do to make it work? Thanks!

 

I dont think anything is different on the plenum itself except you wont be able to mount the map sensor as there arent any provisions for it. Unless you tap it yourself and make sure its air tight.

 

where is the map sensor? that what goes on the back pass side of the plenum?

 

yep

 

hmmmmm...

thanx alot.

 

My question is, why would you want to put an 88 plenum on a 90 intake? FYI, the IAC and EGR ports between the 88 & 90 are different based on the runners and throttle body you use. You will have to use the throttle body gasket for the 88 plenum.

 

i have an 88 plenum that has been ported & polished. how hard is it gunna be to put this thing on? i have the bbk 58mm tb. help!!

 

No problem, the bolt pattern is the same. A ported plenum will not give you any improvement without aftermarket runners and ported intake. In other words, the holes in the plenum are bigger but everything else remains the same thus no significant increase in air flow.

 

yah like ive said before, im a broke ho, so i can only afford 1 piece at a time with this car. runners and manifold are on the way, and headers will shortly follow.

so what mods am i going to have to do to this plenum to make it work on my car? thanx again guys.

 

here's some pics....

No mods needed. Just bolt the sucka on.
