Time to upgrade alternator?

Geez, look at the prices on them.

Are the made out of platinum?

That's more than I paid even!

Lotta work, Diplomat alternators are direct bolt in?

true but the OP will need a larger output than 100A, min output req if going EFI is 120A, sure one may say no way cause I've added up the item draw and sure it might only be 80Amps on paper however, EFI NEEDS GOOD POWER or you will have funny little issues that will haunt you. Upgrade the charge cable to at lease a 4AWG as well, yep its big but it wil stop you pulling your hair out later. I have a brand new Tuff Stuff 100A alternator, new in box thats going on fleabay as soon as I get a chance to upgrade to the Denso unit, better idle charge and output, much cheaper to buy anywhere, just need to spend a little time fitting and happy days ahead

  no harm in getting an alternator that will produce more power than you figure you will need. Nothing is worse than buying the same part 3 times like I did ( stock, 100 amp, then the 250amp) before getting frustrated enough to spend the money to end the issues. Getting stranded at a gas station an hour from Carlisle did it for me!

Yes, the Flaming River alternators are stupid expensive. I will go another route.
