Im looking to do the swap this spring and I would like to upgrade my alternator at the same time. Is there any cheep upgrades? And what belts need to work with it? Im running ALOT of stereo and electronics and I need more power. Any suggestions.

I bought an alternator from him for my 4x4 Toyota truck a few years back. It had a true 1500+wrms worth of amplifiers, plus electric fans, and off-road lights. With his alternator and an Optima battery the voltage was solid with the system running full blast and everything else on.

I wish i knew this before i bought a 93+ 2jzgte 100 amp one

you also have to change the alternator connector if you go 2jzgte one
SC300 is plug and play no mods neaded!

factory is crapy like the 7m around 80 i think
calculate your sterio and your load to ampers and try to stay below 75-80% your laternator peek or your car die at idle and you kill a lot of alternators you can get a lifetime warentee at kragen autozone sc300 one is best 110 amps

other then that there is a couple companys that makes 200+ amp 2jz alternators for $5-600+ but then you have to convert the connector on the alternator or the body connector.
