and I cannot seem to figure out if this turbo is a t22, t25, or a t28. all i know about it is it came off of a nissan, and it has a 4-bolt downpipe flange. its got lots of numbers on it and i have tried to google the shit out of it but i can't make heads nor tails of half of what i find. here are the numbers stamped into the "cold" side of the turbo: M24 Garrett a/r 48 and i guess these are the serial numbers, they are on a little plate in the center: TD 0195J 14411-40P11 466073-5 inside of the turbo there are also some more numbers stamped: "cold" side - .48 "hot" side - .63 if anyone has any info on this turbo that would be great and extremely helpful. i would like to start building this soon, but without knowing what kind of turbo it is makes it rather difficult researching parts.
