Uprating Alternator Options

[Chiefton]

Does anybody here know whether the alternators from the Lexus Models RX300 or GS400 would fit my Gen 6 Celica. I need a larger one as im still struggling with voltage drop from my sound system. Trying to get a similar bolt pattern so i can litterally swap them over, or is it not that easy??

Ideally looking for a 120amp alt, this wouldnt put starin on the engine as its almost double the standard 70 amp one installed currently??

Cheers for any advice

dude, dont get a second battery. That'll make things worse. When you've got two, then the load doubles; making the alternator have to send the power in 2 directions, it's essentially filling 2 leaking cups. Once you start your car, you battery only recharges and sits there untill you bar all the power of the alt. Not untill then will it dip into the batt, and that's usualy bad for the battary. The battary isn't intended to supply power moving that fast, thats why caps are used.

I know that GRIFFGIRL had a high load alternator for the 6th gen celicas. It was a 170V (IIRC). It needed to be re-wound. You can always take you existing alt to a specialty/machine shop and see if they can do it. But what ever you're doing to drain your stock alt, Batt, and a 5F cap, is something i'd imagine is being done wrong. I hope all of your stuff is fused.
