w-bodys_are_the_best Posted November 4, 2007 Report Share Posted November 4, 2007 Hey, quick question, last night my brother's 94 CS sedan blew up when he was on his way back home. He said it was ticking pretty bad, and it started knocking and let out a huge puff of smoke and died, and would not start back up. His 3100 was in pretty nasty shape, it burnt oil like crazy, and has always sounded like shit. I had to drive it to work one day, and he told me he just put oil in 2 days before so it should be good, well it took almost 2-1/2 quarts when I checked it. It probably doesn't help that he beats the shit out of it and puts oil in when it's almost 2 quarts low . He said it does turn over, but won't start, and said it pretty much sounded like a diesel right before it died. I have my black 96, 2 door, and the trans is shot, the dash is out, and the header panel is busted on both ends. I told him he could buy the motor out of the 96 and then I'll part it out. I know the 96 is OBDII, but could you still use it in a 94 and just hook up the sensors that are on the 94, and make it work? The 3100 is in great shape in my 96, and is the strongest 3100 I've driven out of about 6 or 8 of them. He needs a car asap, and he will either buy the motor from me, or I may try and get his cutlass for like $200 and do it myself then either sell it or use it as a DD. It is a teal 94 CS sedan it looks just like somone's display pic on here, I can't remember his name right now. It's got a few dings, and is'nt in the best shape, but with the other motor I could easily get $1200 out of it. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted November 4, 2007 Report Share Posted November 4, 2007 yes, you can! I have a 96 block, but the cams and intake are still the 94 original, but everything works, no check engine lights or anything Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted November 4, 2007 Report Share Posted November 4, 2007 1996 3100 and 1994 3100 are the same exact thing. Only thing that is different area few sensors. Quote Link to comment Share on other sites More sharing options...
Psych0matt Posted November 4, 2007 Report Share Posted November 4, 2007 yeah, i just woke up from a nap, mine's a 3.4, but other than some unused sensors on the block, you should have no problem Quote Link to comment Share on other sites More sharing options...
Crazy K Posted November 4, 2007 Report Share Posted November 4, 2007 1996 3100 and 1994 3100 are the same exact thing. Only thing that is different area few sensors. the upper plenum(for the egr) and the holes tapped in the head (used in 94/95)for the temp sensor are different. you can replace the upper plenum... and rewire to use the 96 3 prong temp sensor. plus the 96 uses roller rockers!

19Cutlass94 Posted November 4, 2007 Report Share Posted November 4, 2007 well you have to use the 1994 plenum cause the car cant read the EGR so you have to swap the plenum's.... big deal since you need to take them off anyways to pull the motor... Ken, the sensor is different between the two, but the hole remains the same. if there is no provision in the head for the Temp sender for the gauge, then you have to convert to the 3-wire.

I was sloppy in my response. the 96+ Heads are not tapped for the sensor, hence the reason you either convert, or drill and tap a hole.

19Cutlass94 Posted November 4, 2007 Report Share Posted November 4, 2007 yeah you need to convert unless you know the exact location to drill and tap the hole Quote Link to comment Share on other sites More sharing options...
w-bodys_are_the_best Posted November 5, 2007 Author Report Share Posted November 5, 2007 What's involved in converting to the 3 wire setup? Quote Link to comment Share on other sites More sharing options...
19Cutlass94 Posted November 5, 2007 Report Share Posted November 5, 2007 What's involved in converting to the 3 wire setup? Simple. You need the sensor and connector ( connector is the same as the TPS connector ) On the two prong side, you need to match up the wires from the current sensor. This will be for your ECM. The single wire will go to the sender for the gauge. Quote Link to comment Share on other sites More sharing options...
w-bodys_are_the_best Posted November 5, 2007 Author Report Share Posted November 5, 2007 Well my brother just called and said he is going to junk it unless I want it. He said I could have it for what the scrap yard would give him so $150-200 it has a few problems, but will make a nice beater. I can't really afford it right now with buying that 350 for my caprice, but I figure I can swap my 96 motor into it, throw the 5 spokes on it and make the money back parting the rest of the 96 out, and then I'll still get around 100-150 for scrapping the shell of the 96. He said he isn't going to do anything with it for a month or so though so I can decide. The body has damn near 250k on it, but the kid my brother bought it from got the car with a fresh trans, dropped in a used motor, and he also put in new struts etc. Granted thats been 3 years ago, but it's in ok shape good enough to beat on for a year or two. I'll throw in my leather maroon power coupe seats in the front and 1 of the 2 back charcoal leather flip down seats I have, it'll be sweet EDIT: car looks just like this 95 on ebay, just not in as good of shape.

w-bodys_are_the_best Posted November 5, 2007 Author Report Share Posted November 5, 2007 What gasket set would I need when using the 94 intake on the 96 motor? Would it be smart to replace the LIM gaskets and the head gaskets also? Neither one has given me trouble in the 96 motor, but it has spent alot of time sitting in the past 8 or 9 months.

[/quote'] They use the SAME gasket set. when you buy a gasket set for the intake, it comes with both types of EGR gaskets. Get the FELPRO PERMASEAL intake gasket set. It is METAL... and is supposed to be re-useable. try Advance Auto, they had it for about $50 when everyone else had it at $75. don't bother with head gaskets if you know everything was fine.
