Help Identifying Turbo

**mb3000** · 03-04-2011, 10:13 PM

I bought my car with these turbos, and I am just trying to verify what the seller told me. I was told they were 15g's and to me, that's what they look like. However I am no expert, can anyone confirm or deny this?

can you find the ID number?

49177 so standard TD04 housing.

49177-?????

Can you measure the inducer or exducer diameter?

It looks like a g wheel. Just don't know which. Is the compressor inlet tapered or straight?

Edit: It seems to read 00620 which would be the part number for an 11b?
I'm guessing I would have to pull the housing to get the diameters?

No I think if you can measure the ID of the compressor inlet, that'll give you a ballpark - especially if the inlet is straight and not tapered.

FYI, inducer diameter is 1.625" for a 15G and 1.580" for a 13G.

Might just be my computer but your pics aren't working, and the inlet appears to be a consistant diameter throughout.

They're just pics showing that 13Gs and 15Gs look a lot alike, and look just like your picture. They're from stealth316, I forget if hotlinking is enabled or disabled from that site.
