Im wanting to clean up the top of the engine a bit in my 92. First thoughts were to get lt1 bracket and run all lt1 acessories with an lt1 alternator relocation kit and also have a/c. Well it would about 1000 or more to do all that with running custom p.s. lines and a/c lines. Now im just thinking of using all stock sero set up but putting the alternator where the smog pump goes and cut the top of the alt. Bracket off just so a littlw more of the engine shows. Anyones done this before or seen pictures?
I did something similar on my old 305. However, I just pulled the whole passenger side bracket off and picked up a March low mount alt bracket. I used a VERY short belt that wrapped around the bottom of the crank, PS pulley, top of the h2o pulley and around the alt.
Can't even see anything under the intake tube and radiator hose.
IIRC, the bolt spacing is way off and I THINK the depth was different as well. Plus having a huge bracket attached to the side of the motor was, in my opinion, useless. And just to be clear, since my h2o pump was reverse rotation I swapped to a standard version, ultra cheap at any parts store. I don't know what year your car is though.
Andrew91GT is running an alternator where the smog pump use to be on a spacer. He's also running a SBF so probably has different alignment on the pulley.
I've gave thought to putting another alternator down there before on the smog pump bracket. 2 1200 RMS amps are too much for stock alternator even overdriven.

I pretty much did the same kind of thing, first with the CS130 (killed 2 of them) and then converted over to a CS144 with a much better bracket in the same spot. I also have my PS pump in a similar location on the driver's side: https://www.thirdgen.org/forums/elec...ons-cs144.html
10 and 12si alternators should have the same dimensions, past that it's up to clocking. The CS144 is larger, I believe there was something like a 17si (something like that) which had similar dimensions.
No. The cs130 bolt space was 7.25" and the 10si is 6 9/16
I might have the parts to check it, not sure, but in the thread, I linked the original bracket that I had that I used to mount the CS130 was actually designed for an SI style alternator.
Yea, no, LB9GTA, what you posted was wrong and my original info is correct, I didn't even have to go and measure alternators, I could just look at my CAD drawings of the parts.
The bottom dark bracket the bracket that you see in my thread mounting the CS130 (go look at the pictures you can see it mounted up). It was sold as a 10/12si bracket and you can see it has a bolt spacing of about 6.561, basically 6-9/16". That outline is an actual 600dpi scan of the original bracket imported into the CAD software.
The bigger bracket is the one that I designed and cut out for the CS144, which I used a bolt spacing of 7.2" (measured from the actual alternator), but 7.25" would have worked fine (you can also see that mounted up in my thread):
In reality, I'm pretty sure that they're actually metric dimensions, but 6-9/16" (for the smaller SI alternators and the CS130 and the CS130D) and 7-1/4" (like I said the dimension I measured/used was actually 7.2", for the bigger CS144, possibly some of the bigger SI alternators) are close enough within the tolerances of the bolt holes that you get using 3/8" bolt holes and I cut a .4" wide slot. There are also new versions of the CS 130 and 144 that have new designations (2something I think) that use the same dimensions)
