The JWT 700BB Turbo upgrade is an excellant choice for a Z32 with a built engine, as the 700HP potential is well beyond the capacity of a stock engine. JWT camshafts are recomended for full potential. A smaller .64A/R exh. housing is available for improved spoolup, but will limit maximum output. These turbos are based on the Garrett wheels and housings found on our "Disco Potato" turbo which exceeds the earlier GT25/30 in compressor efficiency and flow.
