The Eaton M90 supercharger and manifold is back from porting. This is an assembled view of the ported M90 supercharged, 36-lb fuel injectors, and ported/polished intake manifold.
The OEM gaskets will be tossed out and the manifold cleaned of all residue
The PCM and Wiring Harness from a 1995 Regal GS with the 3800 Non Supercharged Engine will be used during this swap. The PCM's EEPROM will be reprogrammed to support the 3800 Series II Supercharged V6 and a 4T60E-hd transaxle. Only one additional wire is to be added to the 3800 Non Supercharged wiring harness (boost control solenoid)
A computer for a 1994/1995 3800 V6 will be used for this swap. The PROM will be custom programmed to control the 3800SC Series 2 engine.
