I have a Turbonetics Stage 4 turbo for sale (basically a TE60). It has about 5k miles on it and is very tight. It has a .82a/r turbine housing and a provision for a DeltaGate external wastegate on the turbine housing itself (gate not included). It has no in/out shaft play and very slight up/down movement. Ran 11.57 on a stock engine (with a front mount and 40s) in my Buick T-Type before I took it out. No smoke. Some surface rust on the turbine housing and center section from sitting in the basement. Price is $415 shipped. Local sale saves shipping.
