Got a ? on a turbo.
 

Ok, I got a factory rebuilt turbo from my friend. It has a .42 a/r on the cold side, but I am unsure of the size of the hot side. It has a T3 flange and no bolts for a downpipe or o2 housing. I did a little research with the serial number on the tag and I believe it is from an Isuzu turbo diesel truck. I also found some info leading me to believe that the hot side has a .89 a/r, but it doesnt look all that big, it wasnt too much bigger than the 14b I just had. If it does happen to be a .89 will it even spool up with my motor (B18A)? Any info?

Got any pics of the turbo? Usually they will stamp the size of the exhaust AR on the inside of the housing where the flange is.

No pics as of yet...The problem is, my friend had it welded to his manifold, and then got it cut off by a shop...so some of the inside where the flange is has been ground off.
