not true. a super 60 is simply a grand national compressor wheel fitted in to a t2. turbonetics just happens to make one. but I agree, doesn't look like it was machined, but the only way to know is to measure as pointed out.Looks like a stock 89 TII turbo. Don't see any machine work done on the housing.
Real Super60 is made by Turbonetics.
You have a stock 87 Garrett TII turbo with a 2.25 inch small flange swingvalve and small wastegate actuator. $80-$200, depends on the condition.For the inducer I came up with 1.70" or 43mm ish I took the full measurment of the wheel not the fins for the exducer so it's probably 60mm so would that make this a TO3 TII ???
Then my next question would be - whats this worth / whats a fair price? I'm not looking to get rich. There is no play in the wheel and it spins freely w/o noise. I originally purchased this for a 2.0L neon (which is now wrecked).
