I don't think there are many turbo'd 3100 w-bodies out there. There used to be a turbo kit designed for a '96+ Monte by Milzy Motorsports IIRC...

 

There was a guy on here a while back who made a 3100 GP coupe run 14's by putting it on a larger bottle...

 

You'd probably be better off doing either a L67 swap or a 3400 swap + turbo.

:thumbsdown:

 

 

At the very least, you'd need to fab up an exhaust crossover and mount a turbo onto that, and then mount an intercooler in front of the radiator, piped between the intake manifold and outlet of the turbo. Cheaper turbos also need oil lines ran to the turbo.

 

 

You'd then have to overcome extensive tuning and fuel issues. Somehow modify the PCM's fuel and spark tables, and install larger fuel injectors and possibly a larger fuel pump. You also might run into compression issues because the 3100 isn't designed for boost.

 

 

Quite an extensive, and expensive project.

The tuning with OBD 1.5 to get the turbo right would deter me from doing it alone...

 

 

Somebody posted a few days ago about OBD 1.5 tuning with a laptop. It seems it can be done without as much difficulty as everyone says.

 

 

Edit right here http://www.w-body.com/forum/index.php?topic=66736.0

 

thats for DOHC cars. OUR 3X00 ECMS ARE FLASH ECM'S. YOU CANNOT TUNE VIA LAPTOP.

 

you will need to swap to OBDII to tune for several reasons. The 94-95 does not have MAF, it has MAP. MAP READS VACCUM NOT BOOST. So that right there you CANNOT tune for turbo. You NEED to swap to OBDII.

 

Then you need everything to mount the turbo and get it plumbed etc etc etc

 

depending on how much boost you go with and what turbo, youll be needing a new tranny cause hours dont hold up good stock.

It all depends on how much money you want to spend. You can swap in a 3400 with no tuning needed, but if you want to start modding the 3400, Id suggest swapping to OBDII. If you swap to any other motor, youll need to swap to OBDII to tune it.

:eek: that kinda sucks.well in either case i need some quick mods to keep up or beat my buddy's 98 bonneville ssei.Is It possible?

Not with a 3100, the SSEI is the L67. Bottle, is the only solution, unless you swap your engine.

that also sucks because i dont believe in NOS (cheater gas)

Im sure the 3100 could be quick, but there just isnt a big aftermarket for any W-body engine except the L67..... :rolleyes:

It is prohibited on this forum to perform an L67 swap. Consequences involve castration and severe internet flaming pwnage. If you can get past all of that though watch out for fires. :lol:

Thats a pretty ignorant comment. Do some research.

 

besides you can only go with about a 75 shot before tuning is needed...

I don't know man, I have spent COUNTLESS hours searching the net for mods for the 3.4 DOHC which is a more powerful engine than the 3.1, 3100, 3400, 3800 Series I and II, yet you can buy practically anything for the L67.

I guess nitrous is one way to go, but how long is a improperly equipped engine to take that kind of punishment. The 3400 has very few things, and practically nothing for the 3.1.

Transmissions on the 3100 don’t hold up well Stock let alone a 75 shot.

your jokeing right? the 4T60-E came on a lot more then the 3100, and i have never had a problem with mine, everyone i know with one has not had a problem with there's, this is the first time i have seen anyone say something bad about that trans. it is a hell of a trans for being FWD, IMO

I'm not trying to be an ass But that’s really weird.. I know a few people on here “Glass Joe†Regal_GS_1989, Glass Joe said “I'm on Trans #3, don't worry. My first one started slipping in gear when warm (130k orig miles) second one was a junkyard trans which went about 20k before shredding the reverse reaction drum. #3 is another junkyard tranny with 80k, and I have driven maybe 30-35k since the install and it's been good. I've never blown a diff yet, but know some people who have, and they were peg-leggerzzzz.†And REGAL_GS_1989 said “Sounds like my cutlass when i bought it. Its a 4t60 E and a 3100 so it should be fairly easy to just replace the diff. I know that it might not be recomended, due to the metal filings, but i got my cutlass with a grenaded diff, trans fluid that was blacker then tar and full of little metal flakes. I replaced the Diff and the housing, flushed out the trans and have put about 20 000 trouble free miles on it sinceâ€Â

 

 

 

I'm not trying to be an ass hole at all.. But there not to strong

The 3x00 series aftermarket is HUGE. Please go to some searching for them before you tell me there is just a few things.
