  1. So you're on the road at night cruisin' in your Z. Slowly you notice that your headlights are getting dimmer and dimmer. You check your ammeter or voltmeter and see that your system is in discharge mode. Oh crap. Belt fall off? I hope so. Nope, still there and tight. oh oh oreo... Well you got that "big" 60 AMP internally reg'ed ZX alternator just a few month's ago, but I guess it gave up the ghost. Trouble is you're in Podunk Kansas and the local AutoZone doesn't have one in stock and can't get one for four days. Now what? Me, I'd rather have a common alternator, one I can get anywhere. And I mean anywhere. About the only sane choice is the GM 10SI body alternator. I know I know, you're thinking, "this GM alternator thing has been discussed to death", well, yes, but if you go looking you will find a variety of GM alternators discussed and the mounting of them is a bit of a mess. Advantage 1: Available anywhere, Advantage 2: Cheap Advantage 3: Internally regulated, one wire. Advantage 4: Available from 100-140 amp. Electric fans, big lights, big stereo, no problem. Advantage 5: Available anywhere. Yeah, again. Mounting is pretty easy after you get past the first issue, ie that the lower alternator mount has to be modified. It has to be cut and drilled. Here is where to get one. I picked mine up from Mopac in Calgary for $134 CAD all taxes in It fits the stock space well, even uses a 8x1.25 bolt at the upper mount point. You need to cut the mount off to leave 1.75-1.8 inches remaining. The cut face must be flat and flush and square the mounting surface. The alternator position is determined by this face, it has to be decent. The drill out the 8x1.25 threaded hole to 3/8" through the whole thing. You'll need a 4.5 x 3/8 grade 8 bolt, washers to space it just perfect to match the plane of the water pump pulley, and a nut/lock. I used a 4L350 drive belt. 35 inches long. PS, I have one of these in my Z and 510. Don't leave home without. Here is where to get one if you're the on-line type: https://www.performance-world.com/ProductDetails.asp?ProductCode=360520 I got mine at Mopac in Calgary for $135 CAD all taxes in. Show Chrome polish was $10 more. Yes really. Cutting, facing and drilling those brackets properly is a bit tricky without a mill. I have a couple of spares if you want one. I can wip them up in 15 min. Or send me yours. All I'm missing here i year/make\model spec to tell the young'en behind the counter when you need to find one in Podunk Kansas. (I've been there, its not so bad...)
