Doritofu Posted October 3, 2015 Share Posted October 3, 2015 So I'm doing a rebuild of this engine, and now I've got this turbo off, checking to see whether it was alright. It seems fine but I have no clue what model it is. And no, there is no name plate so shut up Garrett website saying "simply read the name plate and find the turbo model." -it's not that simple. Both the compressor and the turbine housing have Garrett stamped on them. The compressor has the following markings on it: - M33 -AR.60 -B.C.C. And the turbine housing has .84 stamped on the inside of the split flange. And a single oil feed line w/ return I can post up some pictures if that would help but just thought I would quickly ask and see if anybody knows straight off the bat. and yes I have searched meticulously, I found 1 post with the exact same problem back in 2010 with no replies. So any help appreciated, thanks guys and girls. Quote Link to comment Share on other sites More sharing options...
Doritofu Posted October 3, 2015 Author Share Posted October 3, 2015 Here's a picture that I already had, but like I siad, I can get more if you want. Quote Link to comment Share on other sites More sharing options...
cute wee gem Posted October 3, 2015 Share Posted October 3, 2015 Pull the compressor cover off and measure the compressor wheel inducer and exducer. Easy to do and will give you a far better idea of what you're looking at. Next step (if someone can't visually tell you what it is) is to pull the turbine off and measure that also.

cute wee gem Posted October 3, 2015 Share Posted October 3, 2015 Also what flange on the exhaust housing? Quote Link to comment Share on other sites More sharing options...

Also what flange on the exhaust housing? Kay so I just whipped the housing off and here are the measurements so 75.00 mm for the exducer and it looks like 56.65 mm for the inducer and here's some pics of the flange and the split that shows 0.84. Its got an HKS external wastegate btw. The bolts on the turbine housing look seized as all balls but I'll start soaking them in CRC. Thanks so far.

spiderwebfx Posted October 4, 2015 Share Posted October 4, 2015 Looks like it could be an old GT3076R based on your measurements and this sheet; http://www.turbobygarrett.com/turbobygarrett/sites/default/files/default_images/turbogroup/catalog_pdf/Garrett_GT3076R_700382-12.pdfIt's not quite bang on, but it's the closest I could find. It's also A/R is 0.60 and 0.84 exhaust trim. Edit// Did notice it has water cooling, so maybe not this one. Quote Link to comment Share on other sites More sharing options...

It's not water cooled, thats just the oil feed in the bottom 2 pictures. Oh I see what you mean, the GT3076R has a water line. I'll just have a rummage through the garret turbos.

Doritofu Posted October 4, 2015 Author Share Posted October 4, 2015 No, I mean in the PDF, the turbo pictured is water cooled. Yeah I got you. I had a look through the whole catalogue, couldnt seem to find any with the same specs that didnt have water cooling. Could it be that the center piece isn't from a Garrett turbo and that it's been frankensteined from 2 different turbos? Quote Link to comment Share on other sites More sharing options...

Testament Posted October 4, 2015 Share Posted October 4, 2015 Maybe a to4e of some description? Even just measure the turbine wheel where you can there. Armed with the wheel sizes and number of blades you should be able to figure it. Quote Link to comment Share on other sites More sharing options...
spiderwebfx Posted October 4, 2015 Share Posted October 4, 2015 To4E looks exactly the same. I'd go with that. Quote Link to comment Share on other sites More sharing options...
Doritofu Posted October 4, 2015 Author Share Posted October 4, 2015 It could be, but it would be incredibly unlikely. I'm really hoping that it isn't, but given some of the other stuff that came on this engine, I wouldn't be surprised. Maybe a to4e of some description? Even just measure the turbine wheel where you can there. Armed with the wheel sizes and number of blades you should be able to figure it. Thanks, just had a look through the interwebs and I found some places selling it as a T3/T4e 57 trim. Looking at the specs on one website it had the exact same setup, no water cooling, journal bearings, and an ar .82 devided turbine housing. Looks like we found it fellas. Good job team! 2 Quote Link to comment Share on other sites More sharing options...
