Help Me Identify a Nissan Turbo

B&T, I have never noticed that before in the calculations, but it does appear that it is always small number^2/large number^2 * 100. I guess it is dependant upon the turbine blade itself, and not how the air flow through it. Which would make sense since the Trim is a direct measure of the compressor and turbine blades and not airflow through them.

It makes you wonder why we don't start a database of some sort in a sticky for older turbos as we discover this stuff and post up what we know. this way when we are searching the junkyards we kind of know it when we see a jewel in the rough.

Sweet deal! That reminds me that I need to pack mine up and send it to BEGI as well to have it test fitted on an S4 manifold and have an external setup put on the manifold using a a feed from each runner to the 38mm wastegate. Corky, believes that will cure the problems they once saw with the external gates on the S4 manifold. We'll see I guess...

I guess that since you are going with the S4 manifold and an external wastegate, you are planning on some pretty good power.

Yeah, that was probably a good idea so they would have a basis to go off of on your turbocharger so you get all the right parts the first time. Yeah, I should be making roughly 350WHP @ 18-20psi. It will be a dedicated track car though... Mainly looking for good mid-high power and torque for coming out of corners. The turbo I have, INCON GTBB37 should work well for this application (click to enlarge).

Compressor Plot on 2.0L (Mine will be 1.9L, so should be 'similar')

Well... I got an email from Stephanie at BEGI today. She said that they would need to do some modifications to the turbo to work with the Shanghi Kit. She said it would take about 4-5 hours at $75 per hour to modify it, so to hell with it. I just told them to go back to plan "A" and furnish the Chinese turbo with the kit. It's probably for the best anyway.
The good news is that Corky checked it out and it is worthy to install on my car. It still seems like a nice starting point for someone who is going to do a DIY set-up. It comes with a pretty nice bell mouth partial downpipe that could easily be tied into with an exhaust flange, and it has a T3 flange at the manifold. If I had found this turbo first, before I ordered the Shanghi kit, I may well be doing that myself.
As soon as it gets back from BEGI I will take some complete pictures of all the goodies that go with it and post it on the For Sale forum.
I just wanted to sort of bring this thing to a conclusion. Thanks for everyone's input and help on this.

I was actually having second thoughts before Stephanie's email about changing stuff to work with this turbo, seeing that it is fairly rare and if I ever wanted to change the turbo out I would need to either find another one with the same flanges or modify my downpipe.
So I am kind of glad things worked out the way they did.
It looks like I'm a gonna' git Shanghied!

Don't worry, I know you weren't being critical of their work as it is top-notch. And $75/hour labor be custom jobs is not bad considering it would cost that much or more per hour to take it to a local fabricator that might have no idea how these types of things work or should be designed and then you have an expensive POS on your hand...
