I'm in the middle of selling my engine and turbo combo but need to find out exactly what this turbo is. It is a Garrett reproduction of a Holset HT3B. It reverse rotation turbo with 74mm inducer/109mm exducer and a huge turbine housing.

Also if this doesn't quite make the 1000HP goal does anyone know a turbo shop that can get a bigger compressor wheel and machine the housing. Any info would be great.

Thanks

 

With a small block, I wouldn't bet on it. You can't go any bigger on the inducer than a 3". I sent you a PM.
