Injection: Port injection, 197 cc/min VR6 Bosch injectors, original CIS injector inserts used but CIS O-rings were installed on Bosch EFI injector.

Description: Totally stock car. Originally CIS-E, but too much grief involved in diagnosing CIS-E problems, hence the conversion to EFI. Ignition and idle control taken care of by the original ECU. Air flow sensor had to be retained in order to provide the original ECU with load signal for idle control and ignition advance.
