On the compressor cover, what size is the inlet and outlet?
Is it 3" inlet, 2" discharge? (TO4E series)
For reference.
This pic is a Garrett E cover.
And this is a Precision casted E cover, on a Billet 6262 turbo.
Or is it 3" inlet, 2.5" discharge? Older Garrett cover.
That looks like an older Garrett TE series compressor cover. Very similar to my first ever turbo. I had a TE63-1 that had that type of comp cover. 3" inlet, 2.5" discharge. The spacing between the inlet and the scroll give it away.
Here is a picture of an older T70-1 turbo next to a stock turbo.
It looks like the same style compressor cover as yours.
Also, that could be a Limit Engineering turbo. Especially with that compressor cover, cast aluminum fined backing plate and a Precision turbine housing. My guess is, it's a larger than a 63.

P.S.
(Just got confirmation on this one, it's a 66 P-trim turbo. Thanks Jim.)
