looks like a t3/t04b the to4b wheels had a distinct look and had more blades than most of the other turbos. judging by the size i'd say it's probably a v1 trim t04b. but sounds like it has a blown turbine seal ring.

 

looks like a t-bird snail to me

 

looks like a old post from 2 months ago to me.

 

don't think its a 60/63 t3.

compressor side seems too big really, perhaps its a small t4 compressor. like a 50 trim.

**Edit** God damned noobs why does everyone keep dragging up old ----?

 

In order to find out the trim of the compressor wheel, you need to take the compressor housing off and measure it. This is a 60 trim:




46.50^2=2162.25

2162.25/3600=.60

If it is indeed a 60 trim, just take the .63 exhaust side off his turbo and trade him your .48 exhuast housing. Regardless what trim his compressor side is you have a 60 trim compressor side. So long as you both have standard T3 turbines, all you need to do is swap exhaust housings and STFU.

Done deal~
