I recently got a small Garrett turbo off eBay. It looks perfect for my project (a small, air cooled motorcycle). But I need to identify the turbo so I can find a rebuild kit, and I'm not having much luck.

Center section:
oil cooled only with cooling fins, stamped "433274-1", also stamped "BSF" (I think, I can't read this stamp clearly)

Compressor:
Stamped Garrett, AR33, and either BSK4, or 8SK4

Turbine:
Stamped Garrett, AR36, 15D7, and some more markings that are hard to make out.

Thanks for any info.

 

got a pic of it?

 

 

---- that is small

 

yes it is. i'm looking to turn a 40hp dirtbike (Honda XR650L) into a 70 hp bike and this is the size turbo I need. Now I just need to rebuild it. There's a good chance it's off a small diesel engine like a bobcat or a generator.

Any guesses or suggestions about where I can get more info?

 

not a garrett pro but all i can find is
it might be a gt1544

 

Turbo on a dirt bike...sounds like a good way to kill yourself. I used to ---- myself up regularly on a n/a 2 stroke...I believe you're talking about a 4 stroke though, right??

 

 

yes, four stroke. and it's a kind of big, underpowered dirt/street bike, so it could use more power. But yes, it's still an efficient way to kill yourself.

 

that gt1544 looks real close. I wish I could match the CHRA number with a model number.
