In possesion of a 91 hatch si and cant decide whether to drop in a zc or a sohc vtec, i have both and need some opinons, which ever one i dont use i want to sell

 

zc zc zc zc zc

i have a d16z6 which equals a d15b and it wasnt a bolt on swap, try the zc.

 

the only thing i did notice that i changed on the d15b was the drivers side mount, which was angled (92-95 style) and the map sensor was on the throttle body.its ready to drop in but would it be worth it?

 

coolant switch?
distributor?

 

i have a 95 single cam vtec distributor that i gutted and put my internals in, the coolant switch is a new one to me i didnt even notice that, and also i have a rpm activated switch to control the vtec. at 3800rpm
