Thank you

Can only post one at a time.

Another.

Last one.

I think it's a t3 of sorts; and old. Take a pic of the turbine outlet.

also take a pic of any numbers stamped in the turbine housing, possibly on the inside of the inlet.

We were helping him with this in the PDX thread on CR, it's apparently a tiny turbo from the 300zx twin turbo. Apparently it's fairly useless.

that doesnt look like a twin t25. that looks like if from the 300zx,a single t3 from the 87-89 or so single turbo 300zx...which would be a 60 trim t3 with a .63 a/r housing.

which would be a good turbo on a 1.8L miata.

Exactly what I expected out of that turbo. Looks like a great autox turbo? I don't personally autox myself though.

200rwtq at 3200K on a dynodynamics on a 1.6L isn't bad. that's roughly ~224rwtq on a dynojet.

I don't have a small turbo by any stretch, but I dont make 220rwtq until about 4K. I'm sure you get get better top end with better boost control (the thread suggested he had boost drop issues).

I'd run it on a street car.

Yeah, that's no good. Thanks for posting that thread.
Low and mid range power would be great for autox but there plenty of times where I'm above 5000rpm. Anyway piecing together something is not something I am terribly interested in right now. I'm not knowledgeable yet in the art of FI.
I'll just see if anyone wants it.

150rwhp is still greater than 90.

What's wrong with spamming Josh? (1 post in 3 months is spamming right?)
