300whp on a d16 is not a cheap route... My block is built and im running around 280whp @ 18 psi. you cannt run that on a stock block.
A ported GSR head is better than a ported B16 head.
B16a1's did not come from the 92-95 civic si's they all have d16z6's.
rane, please explain what youve heard. Ive never heard anything bad from that shop.
