So I finally put some miles on her after the build. Nice smooth idle. Cranks right up. Power wise, hard to tell. It's still a 22re and I drive a BRZ when I'm not in this, so......
But let me tell you, the Jag alternator is the way to go. A little expensive out of the box since you have to pay for the core but then it has a lifetime warranty and can be picked up locally, usually. 14V at idle!
Now I have to fill her up & check mileage, not that it really matters to me and then it will be off to the trails.
