20G Turbo Housing ID

[Richard Le]

From all the numbers imprinted on this 20G turbo, is it possible to determine what size turbine housing it has?

If not, how can one figure out the size of the turbine housing?

It's usually stamped on the exhaust (turbine) housing

Turn it over to the exhaust housing inlet - 14 should be cast into it.

Thanks. This turbo is across the pond so I can't see what's on the other side. This is the only picture I have of it. I have asked the seller to check for a stamped number on the exhaust housing.

Yep, that is the BAD DOG (Bolt in) TD06H-20G-14cm2 650 3.3 49179-04100 based on the numbers.

So if it's 14cm2, then I can't really use it with my stock stall?

With the right tune it doesn't make much difference IMO.

Of course there is this JS guy that sells a nice downpipe that helps also.

The compressor numbers don't mean much in terms of exhaust housing. They can and often were replaced.

Jeff's DP will help the spool situation, but if you have one of the "tight" GM replacement converters, it might be a bit lazy.
