Need help identifying a turbo...

[Matt300ZXT]

Ok here's the links to 4 pics of a turbo I'm trying to figure out what it is. It's a 20g with a 7cm MHI exhaust housing, but the compressor is a Garrett housing (as you can see) and has the solid fins where as most MHI fins are the split look. If anyone can help me figure out what mix of turbo this is I'd appreciate it.

That looks like a 50 trim compressor wheel:

That's all i can help you with . Did you get that turbo for cheap? Or have you not bought it yet? ... just wondering why you don't know anything about it ...

I'm working on getting some pictures of the exhaust housing. Are you guys 100% positive that's what it is? And does anyone recall anyone having problems with these turbos, such as leaking like some of the SBR turbos had at one time? If anyone could toss some pros/cons to this turbo I'd appreciate it.

If you are referring to the famed compressor housing boost leak issue. There is a recent thread about this and the fix: here.

Have fun. Did you get that turbo for cheap? How did you come by it? . . .

He wants $275 for it. Has too much shaft play and blown seals, so it's in definate need of a rebuild. I'm just trying to figure out what it's guts are so maybe I can give a rebuilder a better idea of what it is. Some have told me MHI turbos are a little pricier to rebuild, where as Garretts are cheaper. He's agreed to let me take it and send it to a rebuilder to let them tear it apart and see what it is and if it's worth rebuilding. If not, I'm only out the shipping cost. He's supposed to be taking some pictures of the exhaust side so I can see if that'll give me some clues as to whether it's really an MHI housing, or something completely different.

Well. I think it's worth it considering the price plus a decent rebuild price and shipping... You may have a potent pump gas turbo for 500-600 bones. If you ever give up on it, FP is the route to take if you want a Mitsu center section (which has proven to be quite reliable). But the price is worth looking at other companies... If you want good customer service and surity that a future rebuild will be thousands and thousands of miles away, it might be worth the several hundred more for a FP GREEN. They are beautiful, reliable chunks of metal! I prefer the FP red. But I'm quite ambitious on the street...

Eh, I don't know if I want to go as big as that. If this turbo ends up being busted beyond repair, or will cost way too much for replacement parts, I'll just get an E316g. Massive amounts of airflow and "the skys the limit" boost isn't what I'm after. I've never driven a car that had anymore than 300hp (300ZX twin turbo) so I'm not sure I want to go from the 200 or so I was used to before my axle went, to slapping on an FPGreen or Red and making 450 or more whp all of a sudden. That's a big big difference. Hopefully someone can nail this turbo to a "tee" or FP was right as to what it is and I can get away with a basic rebuild and have me a slick turbo.

Anyone got a site on these fella's so I can talk to them about their turbos? I couldn't find DSM Performance or Extreme Motorsports unless that's just a slang name their company doesn't go by (or have as their web address). Aside from the leaking at the compressor housing due to the removable back, are there any other inherent problems with this turbo gumbo?

 

[daren_p]

You probably won't find any of those companies because I think they are all out of business. I have only been in the dsm scene for the past 2.5 years & the mutts were a bit before my time. From what I gather (from reading posts) they were supposed to be the greatest things since sliced bread (the big trend at the time) I think there were alot of issues with them crapping out & not preforming like they were supposed. The origional company went under, changed names etc. etc. you get the picture. Like every other turbo there are some that say they are/were a great turbo. Im sure if you search mutt you will find lots of info on them. I pretty sure Im thinking of the right turbo, if this isn't the case, someone jump in to say otherwise. Don't want to go giving something a bad name that doesn't deserve it.

 

[Matt300ZXT]

Ahh some useful info, thanks. I'll search on that and see what I can find. If I run into the guy tonight or tomorrow, he should be sending me those pics of the exhaust side and I will make a Part 2 so the people "in the know" will have an accurate representation of the whole thing.

This is about the same as a FP GREEN. 50-trim compressor with a mitsu hot side (if it has a TD06H turbine wheel, it is exactly the same w/ respect to the wheels: sleestack chime in here if I'm completely wrong). Reliabily with this unit has been an issue in the past, but it is has the same potential So why would you not want to go with a turbo you're looking at purchasing. It's cheap and if it can be salvaged, it's worth the investment.

Of course, I think FP is right. They are the experts here. And Mike chimed in and agreed with him. So, it is basically a FP GREEN, but with supposedly a bad reliablity track record. Give me this turbo, if you don't want FP GREEN material . FP RED is quite a bit bigger, of course. But, the turbo you're looking at getting can throw down 450 whp. Not that you'll make this "all of a sudden" anyway. You can just run lower boost. The compressor wheel is inherently efficient. The 50-trim has a beautiful compressor map.

Well I've been searching and reading about the Mutts since I posted my last message on this thread. I haven't found it yet, but what exactly was the problem with these turbos? Was it bad machining on the housings and all while making them fit together, or did the center sections not want to work right or what? If it's something like bad seals that could be remedied during a rebuild I don't really see why it'd be a bad choice, unless it was something un-repairable.

I am NOT sure... My research has lead me to most stating that the turbo begins smoking and develops shaft play... I would suspect the thrust bearing w/ these symptoms. A 360 degree thrust bearing would remedy this. And can be incorporated in the rebuild rather easily. Of course, anyone more knowing than me please chime in here.
