[Boost231]

i dont want to switch my bracket do to it being already powercoated so is there any good high output alternators? i found a few on summit but just wondering. im looking for atleast 140amps if not higher. let me know. im also going to call around town to see if there is a place that can rebuild my current one

i put an alternator out of an early 90's 3.1 powered Grand Prix in my car- i think it's only 120 amps, tho.

I dont know if the 86-87 style is the same as yours or not, but I used an O'reilly lifetime off of a 95 Impala ss 140 amp, cost me 120$ there are two amp rated ones, get the 140. Its also has the exciter wire which plugs right in

well i got my alt tested and guess what its bad better then having a faulty dash light

I just got 100amp for my 85

I just got a tuff stuff 100 amp, and it has the internal voltage regulator, bolted right up, but they did have a 150amp one at the site, I'm not sure how the mod's feel about it but i'll post the link so u can look, all i did was get the part #s and then ordered it off jegs heres the link if the mods pull it just pm me.

If ya look on jegs theres some other brands some give u 140 amps if thats what u need.

same 3.8 84-87 so if the bracket lines up on urs then it should work on his bracket, but u'd have to change the pulley cause of the v belts on the 84 85.

i just ordered one from our neighbors @ turbobuicks.com

the 84-85 cars used a different accessory bracket setup than the 86-87 cars- and newer cars used the newer style CS alternators.
my 84 had a regular 12SI alternator in it stock, and the larger 140 amp alternator out of a 94-96 Caprice/Impala SS won't fit. i tried. but i wound up with the CS120 alternator out of a 3,1 powered Grand Prix. it had the offest mounting ears, but i made a simple little adapter bracket to bolt it up. i think it took me 3 minutes to make that bracket by drilling 2 holes in a small piece of 1/8" steel.

Any pics and what year Grand Prix??

 

[mybuick]

any alternator from the 4.5 or 4.9 caddys in the late 80's through early 90's will work just change the pully.

high output alt

if you have a local starter and alt shop they should be able to rebuild it and raise output for less than a new one

89 or so Grand Prix with a 3.1 or 2.8 or whatever the V6 was that year- it was a car i bought for $200 and it came with a spare reman alternator in the trunk for some reason. i just took the serpentine pulley off and put a v belt pulley that i had laying around on it. it has a rock steady 14.6 volts at idle no matter how many electrical things i turn on.

I had one built at a a local friendly alt shop. $75 bucks for a 140 amper that charged every bit of 150 and more. But watch out, I tried to do the same at another shop when I moved and they totally tried to rip me off, denied it, and then started backpeddling when I told them I split the case and told them what I found. After 4 tries, and them refusing to test it (said machine was broke) I gave up and built it myself. Dirtbag redneck ripoff bastards.


The other one still rocks though.4 years, volt booster and all.
