Yup, nismoid that's what the plans are.. I have already used all different types of new style ball bearing Garrett turbos -5s, -7s and -10s and then went to a t51r.. These were only bought because I could tell from the pictures that they aren't standard and they were cheap.... As I said for my spare motor for now they will do until I get my custom made 3076's with -10 housings in a few weeks... Even -10s are too small for 3.2 litre 26/30
