I recently acquired a 98 4Runner 3.4L auto without an alternator. I will be making this into an off road rig over the winter and I will be running numerous lights, communication/navigation equipment, stereo system, winch, etc.... so I want to install a high output alternator. I have researched this and other forums and have some good ideas, but nothing has me convinced in which direction to go. I don't have good fab skills (they are slowly improving) or a lot of electrical knowledge, so I am looking for something that will not require a lot of modification. I found some Denso high out put alternators from Northwest Off Road but from my research here and other places, they seem to be very pricey and have terrible custom service. I have not been able to find the "denso" high output alternators anywhere else. Does anyone know if the ones from NWOR work well and can I get them elsewhere (from denso or toyota directly)? What do you guys recommend for a reliable high output alternator (mostly off road use)?

I have been researching this for the last 3 weeks and not been able to make up my mind. I need to get one ordered within the next week, so any help in swaying my decision would be appreciated.

Thank you.
