Hey Im currently getting numbers and parts together for a B18C build after the new yr(good tax return) Im looking for about 190-220hp at the wheels. I have found a couple diff., types of pistons I want to use, and looking a diff valvetrain options. I want I nice powerband throughout rpm range and the redline doesnt matter to me. I know most ppl shoot for 9200 but anything that makes power would be alright. I have looked at PR3 Pistons and P30 Pistons, which is better. And if someone could help me with some valvetrain info would be great. Im going all motor if that wasnt obvious but Im new with civics and the head work. I have looked into high compression valves and such things and have found some pretty nice cams but they need a specific compression ratio to work correctly. Another question along with the plethra of the other is What is the highest compression ratio I can go and still use pump gas? Premium obviously! Thanks for the help and to any one that helps.
