Hey everyone,
So I’ve got this turbo came off my old motor. Can’t figure out what engine it came from orginally seeing as how its much larger then the stock size of a ca turbo. The part numbers on it are
VL 1048J
14411 50F00
466113-1
Been scouring the internet with no definitive answers. Everything from oddball answers to people bickering about who is an isn’t right. So if someone could give me a definitive answer that would be great. Thanks to everyone for their help.

^ red top is s13, and t25 only came on redtop, s14 black tops had t28. Thats assuming the fast software is nice. I have no idea about part numbers.
