You will never get 220 in a stock casing. Mechman has one and Singer Alternators. I just got my singer Alt and it does about 135A. You only get like 60A out of the stock alt lol.

Sorry for replying to late, but if you want a 220 you will have to fabricate a piece that allows the large case to bolt to the oem bracket. You will also need a longer belt. And if you have A/C forget trying to get it to work.

You can probably try and reach out to Mechman or OhioGen and see if they can get like a 180 in a smaller housing to work, but highly doubt it. Let me know how it goes, because i am upgrading my next week probably.
