I have a 92 mx3 gs, I am attempting to do 1 of 2 swaps i have a KLZE DOHC 2.5 v6 and i also have a KF Engine 2.0 v6, my question is which one will be easier as well as more tuneable later down the road, and also if either of these will mount up with a stock 5speed tranny that is in my car now or if i'll need to buy a new trans before the swap

thanks in advanced

Oh and I would say the KL. It's more common...
