Alternator relocation without P/S
Hi all,
Figured you'd be interested in this on the turbo side of things. Some of you have converted your car to the Nissan alternator for more power and for intake pipe clearance. With some foot work (and quick tool work) I may have an alternative for you.
If you have removed power assist from your car or run a manual rack this will work for you. You hang a 3-tab GM CS130 alternator (found on many GM cars ~1986-1996), rated 80-105 amps from the factory (rebuildable to ~160) from the Porsche power steering bracket. You, having late style cars will need to do some slightly different attachment than I do (early cars have different bracket) but overall it will be the same.
You need the 2-V pulley off an early 90s Volvo 240 alternator. You remove the outer V-groove to avoid cutting the water pump hose. (pictured 4th)
One tab on the alternator hangs in front of the PS bracket. You make a strap (I opted for 1/4" steel plate because I had it laying around) to attach the rear bolt hole (on the back of the alternator case) to the back of the PS bracket. You will need a small spacer between strap and alt case. (pictured 1st)
The stock PS tensioner can be reused again with a spacer. Alt tab has threads in it so bolt goes in from the back. (pictured 2nd)
I have not yet reinstalled my PS pulley on the crank but will do tomorrow to check for belt alignment, but it should be pretty close as-is. I am going to clean up the "strap" some more, weld the spacer to it and paint it.
Alternator I used: http://www.oreillyauto.com/site/c/de...ord=alternator
Easiest to get the plug from the junkyard, and wiring to the Porsche is simple with a diagram, pictured last.
The large 3rd tab on the alternator does not stick out past the plane of the sway bar bracket if you are concerned with tire clearance.
With the alternator on that side, if you have also opted to remove your AC compressor, you are left with an immense amount of space (~8x10x20") alongside the engine. Plenty of room for turbo plumbing or whatever.

nice write up -- but too many oil lines on that side of the engine.
My 951 has the ac delete and runs the Alt on the lower drivers side.
