Hello Guys!! I'm a new members in this forum. I come from QuÃ©bec, Canada. My own language is French. ( Excuse me for the errors) . My question is: I have in my Civic 5G an D15Z1 Vtec-e engine. This Vtec engine makes only 92 hp. I would like to know why this Vtec engine doesn't produce more horsepower? Maybe this engine was build for fuel economy ? I have an another question: I would like to increase my engine performance but I don't want spend a lot of money. Please give me your suggestions for my D15Z1 engine. Thank you !!
