82-83 Info
Thanks to Donn29 for pics of the plugs. For people wanting to change out the plug on the 82-83 you will need to use this post and the charge light mod post by Daves2JZGTE

Round Plug fom Drift Motion, just haven't found anywhere else that sells them.
This write up is for an 84+ set up. For me the alternator is going into 86 6MGE. The two alternators were chosen because of their ease of install. There are no modifications needed besides the optional pulley modification and required connector end modification on the 100A alt. For reference the stock alternator cost ~$100 from Nix99 (2/4/2006). The important thing about trying to fit any non-stock alternator is the mounting holes need to be at 12 and 6 o clock positions and have the same spacing as the stock alternator. With out these requirements you will need to do some fabricating to get the alternator to fit.
This is for the 80A alt upgrade
From: The alt is from a 1992 Camry v6 3VZFE (Round Plug). 93+ alts will not work because of plug design (though you can modify the wiring harness)
Cost: Nix 99 is about $45 last checked on 2/4/06
Dealer $272 Discount dealer price $196 (Mark at Vancouver Toyota with Discount)
Tools:
10mm, 12mm, 14mm wrench/socket
New alternator belt stock length 6-rib IF keeping the Camry pulley. IF changing out the pulley then the stock belt will work.
17mm Drill bit IF modifying 5M pulley A 43/64th Drill bit will work but is slightly larger. I couldn't find a 17mm at the time.
Install:
If you are going to use the 6-rib pulley and a 6-rib belt there are no modifications that need to be performed. I feel that a 6-rib pulley is adequate and should not cause problems. *update* I am using a 4 rib belt and it is working fine. I switched to a 7M crank pulley for my 6M and they only have a 4 rib pulley for the alternator.* To use the 5m pulley, you will have to drill out the 5m pulley to 17mm or 43/64 inches. The belt you use (6 or 7 rib) should be stock length. The connections on the back of the alternator are identical to the stock alternator and are thankfully rotated away from the engine block 90 degrees. This puts the round plug at a better accessible angle and puts the post horizontal to the ground. The post is the same size as the stock post.
General things to note:
The following is a note from Phil D. I copied it from below and I wanted to make everyone aware of a fitment issue that may effect the installation.
Comment from Lechner about upgrading a stock alternator vs getting a alternator designed for higher amp.
Adjustment hole location on adjustment slot (third pic), and closeness of alternator housing to lower radiator hose (third pic).
Side by side, stock left Camry right (5m pulley has been put on Camry alt).
Top down (comparing the backs, stock left Camry right)
Camry alternator installed. (Notice the adjustment hole and closeness to the lower radiator hole)

Thanks to lechner, one2spooku, Supradavis and Wolfgang for the following info about what belt can be used.Just to add a little info, I had to machine some clearance off the back of a 5m pulley (maybe just a couple 100ths, not a big deal) so it didn't rub the camry alternator's case. The particular 5m pulley I used was a heavy solid cast piece as opposed to one of the thin-walled style pulleys. I have seen at least three different 7-rib pulleys on supra alternators. I believe the original factory pulley was a thinner-wall cast piece with four sort-of "dimples" on the inner face maybe for some sort of spanner wrench or SST. I've also seen stamped pulleys with a smooth rolled inner face. I'm sure that pulleys get swapped around wherever alternators are rebuilt and they may not come back with the original pulley, or at least the ones that get rebuilt for Autobone and OhReallys don't. Anyhoo, just something to look out for anyone else doing this mod.
The belt I came up with to switch to the Camry alternator (without swapping pulleys or anything) is off a 1990 Ford Escort. The AC belt (for factory installed AC, but not dealer installed) off a 1987-90 Mustang 4 cyl will also work. The 90 Escort Alt belt is a touch shorter, while the Mustang AC belt is a touch longer. Cheaper auto parts stores like Autozone split the difference and only stock one belt for both apps, which is perfect for us. So if you are heading down to buy a new alternator and belt, It is no extra work at all to simply buy an alternator for a 92 Camry and a belt for a 90 Escort and install just like the parts for an 84-86 Supra, except without using 1 rib on the crank or w.p.
Ford 2.3L was perfect fit belt. Alternator fit right in. Easy swap...No more dead batteries in the morning hopefully. Figured i would share as im stoked. from Mark [at Vancouver Toyota] Nippon Alt was 260 shipped with core dep.
Part # for belt is 4060360 bout 20$ for a decent goodyear
OK, I just completed this upgrade and would like to offer my :twocents: for people who do this in the future and don't want to swap out the alternator pulleys...
When you buy your new 1992 Camry alternator, just get the belt that goes with it! The original '84-'86 Supra uses a 7-rib 36.2" long belt. The '92 Camry V6 uses a 6-rib 37" long belt. The adjustment may be close to being all the way extended, but there was still a little bit of room at the end of mine when I got it tight enough. Everything else was plug-n-play.
Hope this helps!!
EDIT: FYI - The 1991 Camry came with a 2.5L V6 and the alternator is only 70 amps. The belt for the '91 Camry is also a different length.
My new setup
Ebay 130 amp camry alt 92. Gates belt Part #
K070370 about 3/4" in longer than stock 7 rib. Bored out stock pulley to 17mm.
Note the alt shaft is 17 mm. Not 43/64 which is a tiny bit larger. Try to use the 17mm bit if possible.
Comment from Lechner about upgrading a stock alternator vs getting a alternator designed for higher amp.
Here are some comparisons of the alternators:And yes, there is a disadvantage to modifying a stock alternator to higher current. The result is never as good as an alternator that was originally designed for that current, due to the smaller enclosure and compromises required to get a higher peak.
