Since I am in the market for one, I'd like to get a good list together of what different motors go for pricewise. I'd also like a good 'buying a used k-series motor' checklist for those of us buying used, so we can do our best to make sure the motor doesn't have any surprises. Like compression tests (and different k-series motor compression, like the k20z1 having 155-160 across the board vs a k20a2 having ~210-220).


I will update this thread, let's keep it short, sweet, and neat.
