Z34door Posted February 9, 2004 Report Posted February 9, 2004 ok my parts car has a 3.1 also but it is a 90 model. i need to know if there is any dofference i was thinkinabout porting the upper and lower intake and gasket matching it and being able to bolt the car together in a day.my car is a 92 vin T 3.1 multiport and the parts car is also a vin T 3.2 i heard about the upper intake gaskets being different but i think i can solve that problem. with just using 90 intake gaskets Quote
patgizz Posted February 9, 2004 Report Posted February 9, 2004 at one point the bolt holes and bolts changed size(the ones that hold upper to lower). dunno when but i know 90 and 93 are different Quote
gp90se Posted February 9, 2004 Report Posted February 9, 2004 I had a 91 plenum on my 90 motor, the 91 had bolts with rubber boots and the brake booster outlet was different. I used 91 bolts and fab'd up the brake booster line, ran fine till it ignighted. -Jeff Quote
Guest TurboSedan Posted February 9, 2004 Report Posted February 9, 2004 I had a 91 plenum on my 90 motor, the 91 had bolts with rubber boots and the brake booster outlet was different. I used 91 bolts and fab'd up the brake booster line, ran fine till it ignighted. -Jeff i had a '91 plenum on my '90 motor (RIP), and i used the '90 bolts. the bolt holes in the '90 plenum were too small for the '91 bolts because the '91 bolts have a rubber sleeve around them even tho the bolts themselves are smaller - besides the '91 bolts were too small to even thread into the '90 lower intake. gaskets should be the same for every year, but Fel-Pro plenum gaskets are the steel type with rubber o-rings around the ports. the cheaper kind like Niehoff are just paper. if i got new gaskets i would probably just use the cheapo paper variety. joshua Quote
gp90se Posted February 9, 2004 Report Posted February 9, 2004 Malibu, Actually I think I did use the 90 bolts come to think of it. -Jeff Quote
Z34door Posted February 10, 2004 Author Report Posted February 10, 2004 so if i put the complete intake. upper and lower on i'll have to fab up a brake booster line and thats it??? any variances in the EGR?? i want to use this intake bc my intake has 2 broken valve cover holes in it causing an oil leak.

gp90se Posted February 10, 2004 Report Posted February 10, 2004 EGR bolted right on, I used a spare hose I had for a brake line, worked fine. tripple check the plenum gaskets if u have the metal 1s because there not supposed to be reused, and they can leak. -Jeff Quote
Guest TurboSedan Posted February 10, 2004 Report Posted February 10, 2004 i dont' remember having a problem with the brake booster vacuum line, but then again it's been awhile :oops: joshua Quote
gp90se Posted February 10, 2004 Report Posted February 10, 2004 my 90 had a differnt size fitting for a brake booster line, the 91 plenum used a smaller hose -Jeff Quote
Z34door Posted February 10, 2004 Author Report Posted February 10, 2004 well its good to hear........ i'm going to be changing out all the gaskets anyways Quote
93CutlassSupreme Posted February 13, 2004 Report Posted February 13, 2004 vin T 3.2 since when did these cars have a 3.2 liter engine? i thought it was only the quad four, 2.5 liter 4, some other 4, 2.8 liter v-6, 3.1 liter v-6, 3.4 liter v-6, and 3.8 liter v-6 Quote
Guest TurboSedan Posted February 13, 2004 Report Posted February 13, 2004 either a typo, or a 3.1 'T' that has been bored out. joshua Quote
joey b Posted February 13, 2004 Report Posted February 13, 2004 so you are taking them from your parts car and putting them on a parts car (aka lumina)? Quote
Z34door Posted February 15, 2004 Author Report Posted February 15, 2004 joey.. funny......... i thought cutlasses were good parts runners..... LOL it was a typo.. it is a Vin T 3.1 that has been bored out to 3.2 actually Quote
