Celica Forums General Discussion Engine and Performance Alternator Replacement

ok, so i found out today that my alternator is only putting out about 11.5 volts while under load. i think it is time to get a new one. if it weren't for my optima yellow top i doubt i could even get the car started. i found a replacement alternator for $250 from MSD CO. (express auto parts .com - part number 5110) that is a 160 amp peak output alternator. does anyone see a problem with using an alternator that has a peak output of 160 amps instead of the stock one (80 amp)? let me know

if you're not running a system you really dont NEED that much. but as far as charging goes your yellow top should be able to hold up. it's kind aover kill if your car is stock though.

i do have a system... its sorta small now, but will be expanded shortly. i know 160 amp is a little excessive but it is still cheaper than the stock one from the dealer. i shouldnt run into any problems with the other electronics on rectifier and or regulator should i?

I wouldnt think so. your lights might all burn out a tad faster then they used to though lol

awesome. i am getting tired of everything thing in my car flashing every time i do ANYTHING

^^ yeah thats a BAD thing. got a link to the alternator you're talkin about?

yea -

let me know what you think.

i dont trust that site for some reason they dont seem to have much in stock and they dont know what they are talking about i typed in for a performance radiotor for a celica and it brought up a v8 chevy s 10 radiator it doesnt make sense

not many people buy celica stuff. why would they keep more on hand? that doesnnt make any sense lol

Run one of those alternators with the AEM pulley, that way, your system will still charge good, and you'll get the performance benefits of underdriving ^_-

Those alternators are nice, they have a dovetail system on their case that allows you to attach the mounting brackets, so, one altenator will fit many cars; It will ship with the required hardware to bolt it up.

MSD makes nice alternators BTW.

does msd make a celica specific alt or just a universal one?

nice find.

i'll prob be buying it since when my last engine cracked the head, it also cracked the alternator along with it
