i just want to know what is the best upgrade for the dohc zc motor that i can get now....i already have headers exuast stage three clutch cams and camgears intake.......should i get an intake manifold.....

I would say adjustable fpr and a bottle and if your driving i right say hello to the high 13's. Those engines seem to love nitrous. If you want to go the all motor route, start to think intake manifold and head work. good luck!

thanks man when you put the fuel pressure regulater on what else do you have to do i mean youve got to tune it dont you ....im not familiar with fpr.....

1gawd

yup, you would be correct sir, but not a big deal. I used the "butt dyno" tune and ended up with a reliable low 14 sec. daily driver. I put over 20,000 miles on my crx without a bit of problem and sprayed it frequently. fpr will come with instructions.

what kind do recommend or does it matter....

I had good luck with the zex system and b&m upper half regulator. you have to cut your stock fpr to make it work, but without serious fuel needs (ie turbo) it should give you more than enough room to adjust and experiment. As far as the nitrous goes, I started with nitrous oxide systems setup, but that was a real pain. zex was quick and easy to install, and performed without flaw.

headwork is going the more exspensive route but yeild power longer and more reliably. NO2 will indeed give a larger bang but its real easy to get gready with juice. a mistuned nitrous motor is a dead motor. a mistuned ported motor is a running motor that runs like ass.

weight your options wisely. I would always recommend headwork over nitrous for a street car. unless you're building a strip car KISS.
