  • Question : TGP manifold question

    I have a set of TGP manifolds ported to match my 3500 heads, but I need a way to mate them to my GT35. other than finding a TGP crossover and cutting it up, does anyone know of a bolt on replacement flange for the TGP manifolds?

    Won't a generic T2 to T3 adapter work? They're all over eBay. I think the stock TGP turbo is a GT25.

                Ball and Socket flange? You could use V-Bands as well if you can weld it all up. I used a Vband flange for the turbo out-downpipe and they are nice. Only 1 bolt to tighten (which is a blessing in tight spaces) and they look slick and seal well.

                    i bet those manifolds are paper thin to match up to 3500 heads.

                      I've yet to decide my action plan, but I have a couple of ideas on the matter.

                      1. have them welded, and then re machined flat.

                      2. make a set of logs when I pull the engine for the clutch and cam.

                      option 1 is easier, option 2 is better...

                        can you post a pic of how much your tgp logs are smaller then the D shaped ports of the 3500 heads? You did port your logs right? Pics?

                          I'll see about getting pics, but right now, they are mounted to the engine, and it'll be a while before I have them off. I wouldn't recommend them for a gen 3 head.

                              smaller diameter logs on a turbo is actually a good thing. Just don't go TOO small. Keeps velocity high and gets the turbo spooling up into boost a lot sooner....overall making more power.
