StuartW Posted November 28, 2007 Share Posted November 28, 2007 Hi I have this Turbo to fit and need to know more about it? I know it should be a PT67DBB? Its Turbine (Hot) side wheel is 67MM The Compressor (Cold) side wheel max diameter is 84MM and minimum is 68MM It has a 2.5" cold air out to FMIC A 4" Cold Inlet from air filter A 3" V Band outlet for downpipe A T4 Mounting flange Is oil and water cooled On the Cold air polished side it reads BCI A/R .70 and M24 On the Turbo snail it reads A/R .81 And Obviously it says garrett on it too. I have tried to research this but can only find specs on different sized Turbos to mine! Basically I need to know 1 Is it a Wet float or Ball Bearing type? 2 What is its HP rating? 3 What is it called? ie GT67/PT67/To4E etc etc...

Lee P Posted November 28, 2007 Share Posted November 28, 2007 Is there a part number on of any kind? Garrett turbos normaly have a plate on the centre section with the details on. Then you can check ot on the garrett web site. Quote Link to comment Share on other sites More sharing options...
Mike B Posted November 28, 2007 Share Posted November 28, 2007 looks a bit like a 4088r, but it has a different cold housing. Has water connections in the housing so it could be an early dbb? Quote Link to comment Share on other sites More sharing options...

StuartW Posted November 28, 2007 Author Share Posted November 28, 2007 Anybody else know what tubby this is? Quote Link to comment Share on other sites More sharing options...
dangerous brain Posted November 28, 2007 Share Posted November 28, 2007 My vote is water cooled 0.81 a/r exhaust side 0.70 compressor side T67 P trim possibly DBB turbo. Depending on what you read its a 600 odd HP turbo. Quote Link to comment Share on other sites More sharing options...
StuartW Posted November 29, 2007 Author Share Posted November 29, 2007 Does anybody know how i can check to see if its Ball bearing without a full stripdown? I want to check i have the correct sized oil feed? The current oil feed seems too big for a DBB The turbo IS used (But recently reconned) and seems to have a lot of vertical but no horizontal play..which points to a DBB....or a knackered Turbo?

kylestt Posted November 30, 2007 Share Posted November 30, 2007 What size feed line do you have? What size drain line? and i LOLed at the desert smiley thingy LOL Quote Link to comment Share on other sites More sharing options...
StuartW Posted November 30, 2007 Author Share Posted November 30, 2007 Feed line is 4MM (Dont know about restrictor will have to check) Return is 13MM Thanks Smiley is Tumbleweed! Quote Link to comment Share on other sites More sharing options...
kylestt Posted November 30, 2007 Share Posted November 30, 2007 Well i honestly dont know EXACTLY which turbo it is but we can narrow it. Its NOT a PT67dbb, as Precision marks there turbos with Precision Turbo writing, this clearly shows garrett compressor housing. I believe its a GT40 series turbo, how did you measure the compressor wheel? Is it exactly those sizes or just really close? The GT4088R compressor wheel is very close to that. It also the compressor cover resembles a GT4088R on the turbobygarrett.com's website. The big bolt on the housing right near the compressor discharge is what i'm comparing. http://www.turbobygarrett.com/turbobygarrett/images/catalog/Turbochargers/gt40_pdfs/Turbo_1_1.gif Quote Link to comment Share on other sites More sharing options...

The dims and facts posted by me are exact measured with a digital vernier caliper. Any other ideas? Knightrider Quote Link to comment Share on other sites More sharing options...
Homer Posted November 30, 2007 Share Posted November 30, 2007 Maybe I'm missing the obvious here, but if it's not a Garrett, why does it have Garrett written across the compressor housing? It looks exactly like a GT4088R to me Quote Link to comment Share on other sites More sharing options...
kylestt Posted November 30, 2007 Share Posted November 30, 2007 The exhaust housing can vary, for example, i can supply that GT4088R with the sizes from Garrett's site or .68, .81, .96 which is what we end up doing. Several members on here dump the exhaust housing in favor of that undivided .81 you have. Another chance for part #s, if you take the exhaust housing off the CHRA, there MAY be engraving of a part #. Same on the compressor housing. Sometimes a number is engraved right near where the bolts go. Just gotta have the turbo in hand and be able to take it apart, and it may or may not be there :/ Quote Link to comment Share on other sites More sharing options...

It looks exactly like a GT4088R to me If only it was that easy! On the Garrett site it lists the specs and none of them even come close to the specs i have. One has 1MM difference on wheel sizes (Which could suggest it had been re-ground or something) But then A/R's are completely different and not water and oil cooled?

kylestt Posted November 30, 2007 Share Posted November 30, 2007 The GT4088R is both water and oil cooled. But yea i agree the wheel sizes vary slightly, may be just a very old non GT series turbo :/ Quote Link to comment Share on other sites More sharing options...
Ibrar Jabbar Posted December 1, 2007 Share Posted December 1, 2007 Here's a scan of the Turbo specs from Turbo Dynamics. [img]http://i140.photobucket.com/albums/r15/proboost/turbodynamics.jpg[/img] Quote Link to comment Share on other sites More sharing options...
