The '72 vintage fuel system needed a big update. The new set-up consists of two Bosch pick-up pumps, a Bosch high-pressure unit and balanced and blueprinted 720cc injectors. A DTA engine management system installed and tuned by Jon at Ziel Motorsports runs the show. TWM individual throttle bodies. Kaneko employs a prototype HKS GT3540 ball-bearing turbo to produce the pressure. On the hot side, the turbo runs a 84-trim (68mm) wheel in a .63 A/R housing while the compressor section consists of a 56-trim (82mm) wheel and a .70 A/R housing. Both housings have been ExtrudeHone processed for added flow.
