FastSE2DR Posted May 29, 2003 Report Share Posted May 29, 2003 I really need as much help as possible in figuring this all out. As you probably already know from the subject...im working on a turbo kit for a 3100. I want to refrain from as much fabrication as possible. Is there anyone who knows if the crossover from the TGP will fit a 3100? Also, I could use a little help on the PCM part. Ive heard that a TGP PCM will work good as long as i get the whole harness. Can anyone back this up? Is it possible to use my harness with the TGP PCM? Thanks and please help me as much as possible. Tony Quote Link to comment Share on other sites More sharing options...
Guest RedCutlassSL Posted May 29, 2003 Report Share Posted May 29, 2003 i might be doing this instead of the L67 swap, seeing as how I've already got the spare 3100. Keep in touch with me. Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted May 29, 2003 Report Share Posted May 29, 2003 if you use the TGP exhaust manifolds and the crossover, and port match the exhaust manifolds to match the D-shaped exhaust port on your 3100. 3.1Ls had a circular exhaust port Robby Quote Link to comment Share on other sites More sharing options...
FastSE2DR Posted May 29, 2003 Author Report Share Posted May 29, 2003 Well I was thinking...just block off the downpipe on the 3100 and then buy Jeff M's crossover pipe and bolt that in there...save me time looking for a TGP crossover and a lot of fabrication. I have a friend here in town that can make me turbo piping for under $200 installed in any color i want. I will let other people know what I am doing if i get underway with this soon.

If you read in the thread about Tim's turbocharged DOHC, he's not done any computer re-programing on his 1995 Monte Carlo. I would say, first, that the ECM from the TGP will NOT (in theory) work since your 3100 uses the hybrid OBDI system and theres more sensors on the the 3100 SFI than the 3.1L MPFI that the TGP code won't read. I say try it without the code and see what your PCM screems about... remember: Tim's computer accepted the boost, might be the way to go. - RedFox340 Quote Link to comment Share on other sites More sharing options...
Robby1870 Posted May 29, 2003 Report Share Posted May 29, 2003 yeah, thats very true. Plus if you used a TGP chip you would go to Multiport injection, cuz it would fire a bank at a time and not fire each injector to coincide with the intake valve opening, which is what happends with SFI. Anyway, I agree try it witout a new PCM Robby Quote Link to comment Share on other sites More sharing options...
GnatGoSplat Posted May 29, 2003 Report Share Posted May 29, 2003 If your car is MAF, you might be able to get away without any PCM modifications. I'm almost certain the crossover pipes will be different, so I don't think Jeff M's pipe will just bolt on. You could cut/block off your existing rear manifold and weld a flange onto your existing crossover for the turbo. Quote Link to comment Share on other sites More sharing options...
FastSE2DR Posted May 29, 2003 Author Report Share Posted May 29, 2003 Well the 3100s are MAP not MAF. I wish I knew somebody that knew if the crossovers fit. Yeah, im thinking of getting one fabricated but thats just a headache, ya know? But then again it could also be good, considering I will probably go with a T3 or something similar, so then i can just fabricate my own flange anyway. Well thanks everyone for the help...please continue with it. Tony Quote Link to comment Share on other sites More sharing options...

Robby1870 Posted June 1, 2003 Report Share Posted June 1, 2003 My sis's 96 GP with 3100 has a MAF. But anyway, having a MAP and trying to turbo without going to a 2 bar and new ECM isnt going to work Robby Quote Link to comment Share on other sites More sharing options...
brian89gp Posted June 1, 2003 Report Share Posted June 1, 2003 For the 3100 you are not going to find any simple bolt on turbo parts, they are gonna need to be custom made. Not really a big deal though, just take it to an exhaust shop that does that sort of thing if you aren't willing to fab them up yourself. The TGP will run a turbo 3100 motor just fine with some tuning, but it WILL NOT control your transmission. Quote Link to comment Share on other sites More sharing options...
