Alternator Upgrade

[95TacoTruck]

I would like to know if anyone knows of a cheap alternator upgrade for an 83 Toy without paying out the   for the ones in the catalogs. I know that certain MR2's had a 150 or 100 amp alternator something like that does anyone know if it can be bolted to my truck?

i don't know about the mr2 alternator, but i put an ac delco (chevy) alternator in my truck.  i made the bracket myself and i bought a little wiring harness for 12 bucks from North West Offroad.  it's works great for me.

Northwest now  sell upgrade alternators. Don't know the price. But there is one option. The other is to buy an underhood welder with high output alternator. This way you have the best of both worlds. If I saw it right you were asking about an 85 truck also. You can easily switch over the alternator.

If your not using  a  ac unit or air pump on the carb side of the motor it's fairly easy to mount a 1,2, or 3 wire ac delco off the air pump bracket.  Just use spacers to line up the unit to the first pulley and one of those adjustable tensioners you see on hot rods or you can get from a hardware store.  Just make sure you wire in a kill switch for the alternator or your motor might not shut off.

If you use the internal stock toyota alt bracket on just about anyyear from I think 86 to  89  I know of you can bolt a delco 120 amp alt on it..its a simple two wite set up that easy,chep and reaiable as hell..I have it on all my rigs,,even my  toy powered sandrail with the 3tc..say goodby to charging problems forever..the only thing you have to do is space the rear of the bottom bole for pully alignment.I used a metal shock busing that came with a set a kyb shocks.goes inbetewwn bracketend and alt..awesome for winching...along with an optima battery...mmmm mmmm goood.. :up: :up:

finally got a GM 120AMP  internal alternator having troblem with wiring. GM have 4 terminal s.f.l.p Toyota have 3 round socket. How do you connect this???

Mr4x42u.....  Thanks for your  reply about  4 runner roof-rack.        Can you help me with GM alternator wiring VS Toyata wiring ?  My rig is 86 4 runner . ;D

[mr4x42u]

Its been a while scince I looked at it.I will double check this info when I get home.First off I did not use a 5 wire gm alt.I know mine is only 3 wire.One is the charge post and two go to the plug wich you can get at napa.The plug is like 2or 3 bucks.I ran the white direct to batt voltage to the charge post,and the red wire from the plug to switched  12v.I just ran the stock toy charge wire to the charge post and every thing works fine.I will double check that though and let you know..I also used some washers to place the alt as far foward as possible because the stock toy bracket is a little wider.You will se when you bolt it up.The pully alighment is off just a hair,but never threw a belt and you really have to look to see it..will post again when I get home...

Thanks  Mr4x42u ... Look forward to talk to you

[guywithuglyyota]

Do you guys know if these upgrades are possible on a truck with an external voltage regulator. I have a 81 early model toy pickup

[WHITE_TRASH]

Yup its just the same as replacing an internal regulated one.  You just pull the regulator out of the system.

Anyone have a part number for the Delco 120 amp?

So is everyone is using the 120A 17SI for this swap? What about the 140A CS144 if you changed the pulley from serp to V-belt (from the link toyhatsu posted)

[guywithuglyyota]

Kyota, thats the route I want to go. I have read the cs144 is very reliable and makes lots of current at idle. Im just wondering if it will fit in the stock location, probably has the same case size. Here is a site I found, there customer support is pretty good. They specialize in all sorts of conversions and amp up all the alternators they sell.

[KYOTA]

According to info from toyhatsu's link the cs144 (140A) is the same size as the 17si (120A)

[cancel]

has anyone attempted the cs144 swap yet? i'm about to try it and i want to see someone else's. if noone has a write-up, i figure i could do one... it's the least i could do after lurking for so long (2 years)

[musclesliver]

how about using a Tacoma alt???

[hornett22]

this is all you need.more amps means more heat and less life.

[musclesliver]

[hornett22]
