140 amp alternator upgrade
Well after many up grades I've had my stock 55 amp, second gen 80 amp and a 3rd gen 100 amp alternator. I've been reading the 105 amp upgrade thread by Big_Ern https://www.rx7club.com/showthread.p...lco+alternator
I needed more power to handle my rather large system, so here is a 140 amp AC Delco unit. As you can see in the pictures, I've done many electrical upgrades: 2 second gen fuse boxes, upgraded 4 gauge power to the fuse panels, 4 gauge ground to the alternator and 4 gauge direct to the starter. Never do an electical upgrade without upgrading your grounds!
Not hard to do. I already installed a Pineapple Racing alternator relocation bracket from a previous install. The hook ups where very easy: S connector to back of alternator (direct feed), F connector was not used, L connector was connected to the stock L, P connector was not used.
I picked this b eauty up from luiml73 as he was stripping his wide body down.

Yep! The system is over 1200 watts. One amp has a max 35 amp pull while my sub amp can pull 80 amps. Then you add in a the electric fan, fog lights and the rest of the draw on the car it all adds up. Its better to have too much then too little. Put it this way, my lights don't dim anymore when this thing is cranking with everything on with it.
Oh, if I want to run a small microwave or blander I can handle that too.

Man John,
That is one disgusting engine compartment - I even think I see a drop of oil somewhere there!
Seriously, that is one awesome compartment, I am quite envious

Jon, I don't know the part number as I got it off a member here. I think it will mount in the stock location, but not with a strut bar. This thing is alot bigger then stock.

I've seen Re-Speed's and they are quite nice. To be honest, I just like how that particular one looks. My buddy has it on his car as well cleaned up real nice and it looks pretty awesome. I'll send you a pm.
