Alternator upgrade - ZR-1 Net Registry Forums

secondchance · 04-22-2019

In preparation of Spal fan upgrade I am planning, I decided to upgrade my alternator to 200amp. Powermaster is an option but figured I would try Nippon Denso version customized to work with CS144 cars.
Mike (5abivt) had done this conversion a couple of years ago. His choice was DC Power unit. However, his difficulty in adopting Nippon Denso connector to CS144 was noted and led to my decision to go with Quality Power Alternator since Quality Power Alternator offers conversion harness taking the guess work out and keeping it looking professional.
Additional 8 ga. cable was added between the alternator post to battery to allow for additional current and, while at it, added additional 18 ga. between the battery and HVAC controller resulting in some extra oomph to HVAC fan.
Note Phil's custom spacer that allows slick adoptation to passenger side mounting bracket.

All buttoned up. Shame that most of the alternator is hidden behind vent tube, harness and bracket.

Of course, while at it, a perfect opportunity to replace fuel pressure regulator with Phil's upgraded version.

The work was done at WAZOO garage with invaluable help from Jim and moral support from Nelson and Charlie. Thanks guys!!!
