^^^NA's like some back pressure so "big big exhaust" might not be optimal.

I have heard that the ka24 rods can be a weak point.
I would be shooting for over 180hp.
the head would be worked over and portmatched to the manifolds. A larger TB would be used also. I would like to have a step tube header.
i would have the crank knife edged, micro polished, and rebalanced along with the rotating assembly.
if I was to get forged pistons I want to know if the ka could do 12-1 or maybe even 12.5-1. NA's can produce more than 100hp per liter, why could'nt the KA(if built properly)?
