Alright folks,
Time for another alternator thread. I will try to keep this from being a "I'm dumb, just tell me what I need" thread.
I recently bought the AR Engineering Denso brackets and now I am looking for the right alternator. I think I have zeroed in on the one, 1991 Toyota Land Cruiser 90 amp unit (13562). @mopowers is using one. From what I gather there is a "mini" and a regular sized Denso. I had a 1991 D150 120 amp alternator but it was a bit to big. The Toyota Densos are smaller.
I'll run you through my amp draw as close as I can come up with:
Pro FLo 4 EFI = 15 amp max current draw
Aeromotive Stealth 340 pump = 15 amps
Electronic Power Steering = 9 amps
Contour Fan = constant draw 33 amps / start up 135 amps
Relays for the fan and fuel pump. Edelbrock recommends any fuel pump above a 10 amp draw have a relay. I will be using the @crackedback headlight relay kit. The car won't have a stereo or A/C.
I have always rad that you just add up your current draw and choose an appropriate alternator. With all the things I have listed it comes in at 74 amps and then there is the headlights, wiper motor, and any other basic demands I may be missing.
Is a 90 amp the right size?
