I have fallen over a killer deal on a turbo but I need to figure one thing out. The compressor housing on this turbo says GT35/40R...that probly obvious at this point. But some ***** tried to polish the turbine housing and there are NO numbers left on it at all. Does anyone here know any way to figure out what A/R the turbine housing is without the numbers stamped on/in it?

 

Find the company and look how many turbine A/Rs there are for the A/R compressor you have and I guess just.....guess. Not too sure, but looking at what sizes are available will help narrow the gap.

He polished the exhaust side?

 

Occasionally the A/R numbers are stramped on the inside of the turbine inlet. But if not, guessing sounds like your best bet aside from having a turbo shop measure it.

 

SSAC ! I dont think garrett or precision will have GT35/45 on the compressor housing, it will most likely say m24 ar70 or something of that sort, not gt 35/40

Yup

Here are 2 amost useless pictures that I was sent of the turbo, I can go meet the guy to put my hands on it, but I haven't had the change. It IS a garrett turbo and I know that it's a ball bearing. The available A/R's were .63 .82 and 1.06. The .63 and the .82 would work for what I want, but I really don't think I could even use a 1.06 on a B16. I will have to get a better look at it..the guy has NO idea what he has, so he isn't much help, but I thought I would at least run it by everyone here just to see...It almost looks like they tried to shine up the hot side with some sort of spray ----...He go it at the SEMA show off of one of the displays, I guess it's an older model of some sort, right after they first came out with the GT series.
