Marcus18 Posted February 23, 2004 Report Share Posted February 23, 2004 I was looking at one of these. it looks alittle bigger. Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted February 23, 2004 Report Share Posted February 23, 2004 are you looking at a Mitsu TEO4H from a 2.5L Turbo Dodge 4cyl? that is the turbo i have on my Lebaron GTS right now. i have a garbage TEO4H turbo in my garage right now, along with 2 good TGP T25s. i could have sworn the TEO4H was smaller (?) but i'll take another look. joshua Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted February 23, 2004 Report Share Posted February 23, 2004 not sure what you're thinking about with the mitsu turbo, but the 2.2 Turbo Dodge engine uses a much larger Garrett T03. it might be better suited to the 3.1 than another tiny turbo like the TE04H. the 2.2 T03 uses a standard T3 flange with a Chrysler specific bolt pattern, just like the TE04H uses: the smaller turbo in the pic is one of my TGP T25s, the larger is the T03 turbo from my Lebaron's original 2.2 T2 engine.

Marcus18 Posted February 23, 2004 Author Report Share Posted February 23, 2004 I think I'll pick me up a t3 then. ...there is one on ebay at $10.50 with no reserve thats the one I'm watching and wanting. it will be over in 3 days. if all works out I'll make a cross over, down pipe and alittle better headers to fit. I think this would free up some power in the top end as our current manifolds (according to corky bell) are the worst setup. hopefully marcus Quote Link to comment Share on other sites More sharing options...
90TGP Posted February 23, 2004 Report Share Posted February 23, 2004 Depending on the year and if they had the TI or TII motor, they could have come with the Mitsu or Garrett turbo. Quote Link to comment Share on other sites More sharing options...
Guest TurboSedan Posted February 23, 2004 Report Share Posted February 23, 2004 Depending on the year and if they had the TI or TII motor, they could have come with the Mitsu or Garrett turbo. yeah Chrysler can be a bit confusing. all 2.5 turbo engines are T1 and they all have the Mitsu turbo. the 2.2 turbo engine however could be a T1, T2, T3 or T4 motor. T1 - all non intercooled 2.2/2.5 turbo engines. all 2.2 T1s came with a Garrett T03 turbo except for the last year of the 2.2 T1 in '88, which came with a Mitsu. after that it was 2.5 with a Mitsu turbo only. T2 - 2.2 intercooled high performance ('87-'89 only). T03 turbo only T3 - 2.2 DOHC intercooled Spirit/Daytona R/T engine. it is a TB03 turbo with a standard T3 flange and a standard T3 bolt pattern ('91-'93) T4 - basically a T2 motor that uses a VNT25 turbo ('89-'91 i think) basically any intercooled turbo dodge (T2-T4) is rare. cars with the 2.2/2.5 T1 are very common. joshua Quote Link to comment Share on other sites More sharing options...
Jeff M Posted February 23, 2004 Report Share Posted February 23, 2004 Nice job mali, the thing I like about these/some of these is the turbo outlet already bends in the right direction for us too . Downpipe is a little work, matching the turbo to the 3.1L motor will take some research but sounds like there is plenty of info on these, and their upgrade counterparts, of which I like Hahns Racecraft and their huge efforts for some great upgrades, even custom parts to overcome some challanges to power limits and control.

RareGMFan Posted February 24, 2004 Report Share Posted February 24, 2004 Jeff, how is your turbo upgrade looking/coming along? Any hints on what kind of power gains we can see or what type of turbo you're trying to make work? Quote Link to comment Share on other sites More sharing options...
Jeff M Posted February 24, 2004 Report Share Posted February 24, 2004 Jeff, how is your turbo upgrade looking/coming along? Any hints on what kind of power gains we can see or what type of turbo you're trying to make work? Getting caught up after a week of getting things done for a TGP owner here who flew in from Cali to get his TGP. Did tons of work to it, stripped it down to the subframe, cleaned and coated it, all new wires looms, entire engine bay painted black/clear coat, new suspension, new performance tranny, new performance engine rebuild, my heads, interior work, and tons more. I offered to him to take his TGP and have it to enjoy, wash and wax, play with it and have it with him but for now he still has the T28 I came up with for him, still has too much backpressure but is fast enough till I send him the turbo I finally end up getting. That call to the turbo supplier is on my list this week, the guy I have has talked to Garrett direct, France where the turbo was made, Mexico where Garrett has another plant, been all over looking for basically a better turbine housing. Thing is with all those great Garrett GT turbos is they are mainly being offered to satisfy the huge demand of the Asian 4 cylinder crowd, and their turbine sides are more geared for this and not a big 3.1L motor, might be better for sure but does not allow a lot of options to flow the exhaust we have. Backpressure tests are the only real way to know how any turbo is working out, just like explained in my Turbo Cam post a few days ago. There are some other variables that will affect backpressure such as A/F mix, but if that is not too rich then backpressure is the way to confirm successful results. So the plan is to first try to get a bigger turbine housing and a better A/R, to work with the compressor wheel that is already good for 300-330 hp, maybe more which will show up in tuning, if that does not work, have a few backup plans to go with on the turbine side. I am also sure of it from tests I have done that if I can get a swap over larger turbine housing, that stock or chip’d TGPs will see big gains too, we really have a backpressure issue that needs to be address, and is why I don’t go crazy running real high boost with the chips I sell. So soon I hope, it takes time especially from a small market group to get results but persistence pays in the end. Jeff M Quote Link to comment Share on other sites More sharing options...
slick Posted February 24, 2004 Report Share Posted February 24, 2004 Get the t3. Quote Link to comment Share on other sites More sharing options...
Marcus18 Posted February 24, 2004 Author Report Share Posted February 24, 2004 think a 42. a/r t3 is big enough? It off a pre 90 saab. calculated it up and it doesn't look like it flows enough in the top end. I've been looking at a to4b 40 trim. anyways gotta go start takine my car apart to put a new rans in it. marcus Quote Link to comment Share on other sites More sharing options...
