Please help me identify my new turbo
Just bought a new turbo and I was told it's a precision 6176 turbo. But the guy selling it didn't really know too much. He bought a bunch of random parts to turbo his car and I guess he ran out of money because he started to part out everything. But I got the turbo for $400, he said he paid $1,200 shipped for it last year and it has never been on a car or ran yet. Here are a few pictures.
Here is a huge list of all the precision turbos.
http://www.precisionturbo.net/Wc2a33a0fa1ef3.htm
The cold side A/R is 70 and the hot side is 68. It says on the back of the hot side th6876 but I know this turbo isn't goo for 800hp.
So as of right now I know the cold is ar 70 hot is ar 68. So common sense would mean the turbo is a 6870? But I have never heard of that and it isn't made... So what do I have? It's a th68 something. Either way I'm happy with it. It should be good for what I'm shooting for. I'd just like to know what it's called. Thanks.

Re: Please help me identify my new turbo
that a/r on the housings mean nothing with what turbo it is. you'll have to measure the wheels. every compressor housing i've seen from precision has their logo on it.

Re: Please help me identify my new turbo
Hot side is 64mm and 73.7mm
Cold side is 61mm and 82mm
I know it doesn't really matter but the actual housing on the cold side is 60mm and the hot side is 75mm

Re: Please help me identify my new turbo
I threw the numbers up on the picture you posted to make it easier to see...
Going off of their website it looks like it's a 6176E Boosted rated at 680hp. But my housing on the cold side is 2.5" at the narrowest point. Exhaust side is 3" at the narrowest. So I'm not really sure what I have on this list...

Re: Please help me identify my new turbo
its just a different housing... E is .60 a/r and S is .70 a/r.
S covers are 4" in and 2.5" out.
E covers are usually a bit smaller, but can still have up to a 4" inlet, but are limited to 2" out.
Either one can be "antisurge" ported as long as it is a 4" inlet
As a rule of thumb, smaller compressor housings tend to do better in high-boost levels and larger compressor housings usually do better in lower boost levels. It sounds backwards, but thats just how it is...
yes, if your measurements are correct, then you have a 6176S
