A friend of mine is using it on his R32 GTR with a T-88 turbo and has not had any trouble with it. His car put down 5xx whp on low boost and 852 whp on high boost. I think it is well worth the money if it can take the abuse his car went through. Btw, the stock R32 and R33 GTR's come with the same tranny as the Z32 and it is even easier to break on the Skyline.
