"slightly larger" case 3G alternators on 2.3T

[ElaborateDream]

So, I've burned out another voltage regulator. Took this one almost a year. Alt still tests beautifully at a real alternator shop (yes, they still exist).


Was thinking about going over to PA-Performance to go to an internally regulated 3G alt.

They show one alt for a 2.3 car: http://www.pa-performance.com/Script...p?idproduct=46

I was thinking about going for the larger 5.0 case: http://www.pa-performance.com/Script...p?idproduct=49 , which I know how to install on a V8 car... does anyone have dimensions or experience with running these on a 2.3 car?

Cause, 130A sounds a lot nicer than 95A for an extra $30.

The 130G Alt fits with minor grinding on a serpentine equipped car. On V-belt cars its possible that it fits fine, not sure since my car is a serpentine setup.

Good point, this is on a V-belt car.

Anyone tread this path before me? I found the NA Thunder boards talking about the serpentine setup, and I'm OK with being the first to do it on a dual V-belt setup, but I figure it behooves me to ask.

I've had one on my SVO since I first got it back together in 2007. I didn't have a stocker but had the 3G on the shelf, so I went with it. I first used it with the v-belt setup and later switched to the serpentine after having lower crank pulley issues with the 3rib, then a/c belt slippage using the 2-rib setups. The serpentine belt setup has solved all my belt issues. The 3G has been with me the whole time without issue. Just needs a bit of bracket modifications to fit. And the PA performance regulator so the dash light will still work.

Its been done on a V-belt setup before, because of the lack of the large aluminum bracket I don't believe there is any clearance issue, just need to tighten the alt down in a different position than stock.

Use a 87'-88' Tbird alt.

Ick. No. You can keep the fire-prone 2G's if you like.

I've got a 3G on the TBird (2.3T) with just the basic stock (early) V-belt alt bracket. I'm running a manually-tensioned "serp" belt, and haven't had any issues with slippage, etc.

D'OH. I just realized I haven't re-uploaded the TBird pics after the lost of my last webhost, so sorry, no pic at the moment.

Our '85.5 SVO has a 3G using the stock v-belts. No mounting modifications needed.

Our '84 Capri Turbo RS has a 3G running a serpentine belt and needed some grinding/sanding because the case runs into the mounting bracket. Minor and unseen once the alternator is installed.
