How to find AR

[DarthBuick]

I posted a question about how to ID the turbo that came on my GN. I didn't have much info at the time. I got the measurements tonight. The turbine wheel dimensions are compressor 64 MM inducer and 95 mm on exducer The exhaust is 66mm exducer and 74mm inducer . Bison had said it was a P trim. I wand to find the AR ratio. The center section has 430683 stamped in it. The housings are polished and say nothing What is the AR and turbo ID. This is going to be a street car now is it overkill?

Have you looked at the compressor housing for a stamp?

It has been shaved and polished. The center section has 430683#

You might have to calculate it yourself.

I fount that the exhaust has a .82 AR. The compressor side outlet has been cut off and a different one welded on. Where do I take measurements to find the Compressor AR. I am just trying to find what I have.
