im going to rebuilding my ka24de and am going to be doing a few things to it while at it. my setup is gona basically be:
intake
headers
full straight 2.5" exhaust
sohc pistons
balanced crankshaft
port head on intake side
port matched intake manifold

i think thats basically it. but my question is, is it worth boring my throttle body with the power ill probably be putting out? or would it mostly be reccommended for higher power cars like turbo cars or something. if it is a good idea, what the max bore i should do? thanks
