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!!! Last edited by secondchance; 04-22-2019 at 08:13 AM. |

https://www.qualitypowerauto.com/ite...-7.2-Mount.htm Invoice says 8112-ND-200A, rear post 6S 2.3" pulley and W3030D harness. Again, passenger side post needs a spacer and thread needs to be bored out for our LT5. Cost was $485 including the harness. Talk to Kevin. He was very helpful. |

Yun, nice mod and I did not think so soon. Thanks for sharing and costing me even more money.....LOL.
Maybe we can convince Phil to sell his custom spacer? Maybe Kevin will consider a group buy too? Sent from my iPhone using ZR-1 Net Registry

Kevin is the contact @ Quality Power Alternator? I would think the later tech Alternator would work better/last longer

These alternators evidently have high RPM capability. Kevin was recommending 1.6" pulley (if I remember correct) and I went conservative with the largest pulley offered - 2.3". This combo requires 80 inch belt. |

How is it working out for you so far ( yeah I know it was just recently done) but I am planning that mod along with the HVAC fan wiring. if I can get a boost out of the fan I will take it I also did the Regulator update, not needed, but rather get it done before I NEED it done

I’ll try to get on the right time zone and give him a call. Not into washers and will check with Phil. If nothing else some specs to have Carter make a run. Thanks again! Sent from my iPhone using ZR-1 Net Registry
