Diameters of inducer and exducer on both wheels?

Very interested, obviously have to assume its not a real Garrett. Is it identical to a real 2871?

What are the compressor flange measurements?

"wet float type" bearing? Or ball bearing?

does it not hit block??

interested as well in the compressor/turbine diameters

Can you show a pic of the turbine side with the wg flapper open?

also interested would it be direct replacement for my garett 2554?

Yes it would bolt in place.

It is not a true Garrett. I will pull measurements today on it!

How hard is it to reclock one of these the outlet is pointing the wrong way for my begi setup?

Updated first post!

-Sam

It is pretty easily clocked, we haven't mocked this up on a Miata yet, so no idea if it will impede with fitment.

-Sam

specs look good! quick glance it looks pretty much like a journal bearing 2871 (48trim)

Lol "enlarged wastegate port". I was curious because I've had to dremel out a couple churbo's already. Takes for damn ever.

BUMP!

-Sam

any word on will it fit on miata clocked to exit down.

Tell me the measurements of the compressor inlet and outlet, and tell me if it's journal bearing or ball bearing. After that, I might offer you money for it.

Should have no problem fitting a dowards clock, as a matter of fact it should anyware almost anyware a T25/T28 would.

Yes its Very much like a 2871 just with a little more top end.

Compressor inlet: 2.75" and outlet is 2" I will have the shop double check on monday.

It is oil and water cooled journal bearing.

I will call you then monday morning to discuss
