august Posted September 17, 2005 Report Share Posted September 17, 2005 just got this thing off ebay.. supposedly it was rebuild by a peugeot dealer back in the day, i'm stoked.. hopefully the next time i post a turbo it'll be a ball bearing GT series or something Quote Link to comment Share on other sites More sharing options...
Trevor Posted September 17, 2005 Report Share Posted September 17, 2005 Damn that thing looks nice! I saw that auction and knew you'd be all over it... and then looked closer to see your name as high bidder. haha. Awesome find, not a bad price either for a brand new turbo. That for the 89?

august Posted September 17, 2005 Author Report Share Posted September 17, 2005 Hells yeah! Bean was giving me some good ideas on turbo's for the danielson car.. not sure if i'll be able to do it though. might have to take some welding classes or something first Quote Link to comment Share on other sites More sharing options...
Trevor Posted September 17, 2005 Report Share Posted September 17, 2005 !!! It's on. I'll help you fabricate some stuff. All we need is a mig attachment :--) I still want to get rid of that turbo and put something else on my rig. You thinking new manifold or what?

august Posted September 17, 2005 Author Report Share Posted September 17, 2005 i was thinking the downpipe.. i'd like to do a manifold but i think it'd be a pretty big learning experience. i should really start doing research on the exahust housing of a GT series turbo, and see if its compatible with anything.. i guess if that was the case we could use that to at least mount to the turbo (assuming its 3 inch), then hack it half way down and make our own from there on back.. yeah? then again, i wonder how much some shop would charge to just do a complete turbo back system.. hmmm Quote Link to comment Share on other sites More sharing options...
Trevor Posted September 18, 2005 Report Share Posted September 18, 2005 yea. It'd be awesome to find something that mated to the manifold, but wth a better downpipe flange that could accomidate some fabricated downpipe of a larger diameter... and improve exhaust flow by losing the chicane style outlet. We gotta look into it, but i think that the bolt pattern to the manifold may be the same as a more conventional t3, but the inner diameter is circular? if that's the case we may just be able to portmatch the stock manifold to a different turbo and use the same bolt hole pattern. that would make things easy on the manifold side.. then the exhaust would be no prob as long as it's something like a simple flange-style mate.

august Posted September 19, 2005 Author Report Share Posted September 19, 2005 no doubt, if we could use the oe manifold it'd be dope.. the chicane style turbo outlet hasn't hit me until i really had a look at this latest turbo.. like really, you can see *half* of the exhaust turbine! then again, it probably isn't *that* much restriction, how bout saab downpipes (from v-m's site) Quote Link to comment Share on other sites More sharing options...
V-M Posted September 19, 2005 Report Share Posted September 19, 2005 That is very good "as is" turbine housing, that will give 50-70hp more with good DP than original turbine housing (exhaust pressure is low). Just add 3" pipe from turbo to "this narrow place near rear diff." and rest can be normal size and you get much more power out. Aaa... but you need this catalysator there... maybe add some high flow cat. But you can remove this middle silencer (nearly no extra sound was coming). I findout at normal std turbo max boost were 0.8bar after that heat load was increasing rapidly but that turbo with better turbine housing and DP can do bit over 1bar -> 240-260hp? About that picture, I only change that DP and rise boost with bleeder (0.2bar -> 1.1bar) on my Saab and get 165kW from wheels (automat and originally 147kW from engine) Of cause small hand works also head etc... but point is eaven in that flange it's 2.25" from start and tight turn and then changes to 3" and still giving good responce This Dyno result is on my page also.

august Posted September 19, 2005 Author Report Share Posted September 19, 2005 hmm, so different exhaust housing + 3 inch downpipe would be a power gain.. but what about "that narrow space".. what about doing just the 3 inch downpipe, then run the stock system back from there? (or is that what you were suggesting above?).. Quote Link to comment Share on other sites More sharing options...
V-M Posted September 19, 2005 Report Share Posted September 19, 2005 Well, bit difficult to tell cause I don't know right name on that where back wheel support is connected and it's girder? I this picture pipe goinig trought there it's under back silencers. That is made in 2,5" and it's very difficult to keep of hitting edges on that narrow place. And it's 3" from turbo to this "narrow place". Next time I'll go to have car up I'll have some pictures below of car. But any way, of cause 3" DP helps eaven short one but like they say "Bigger is better" V-M Quote Link to comment Share on other sites More sharing options...
Bean Posted September 20, 2005 Report Share Posted September 20, 2005 One mod I did on the exhaust housing was to port it out some more. That one stud that has it's "bulge" right in the middle of the flow path. I used a die grinder and a nice bit to take that down substantially, as well as shape it's profile to make it more "aerodynamic", as well as did some general cleaning and polishing. I also used the flange from the exhaust pipe and I match ported the exhaust housing to the pipe better. I didn't go too crazy though as I didn't want it to start cracking all over. (So far so good). I did it for the car my brother had at the time and he reported good results - but the car was bone stock so it would have been hard to tell. I now have this barely used turbo in my garage waiting for me to do the engine in my car. Once I use it up, (or have more money to spend) I plan on the GT25 or GT28 upgrade.

V-M Posted September 21, 2005 Report Share Posted September 21, 2005 Go for GT28 at least, GT25 limitation is ~270-280hp on engine. I have GT25M on my Saab (originally). V-M Quote Link to comment Share on other sites More sharing options...
Yq397r Posted September 21, 2005 Report Share Posted September 21, 2005 looks like a nice buy, very clean factory turbo. I saw that one on there for sale. Hope it runs as good as it looks. Quote Link to comment Share on other sites More sharing options...
