i want some more oppinions of hp guesses of my fresh jdm zc which new had 135 hp in japan, with cold air intake header, catch can, full greddy exhaust high flow cat and chipped ecu, im thinkin 150 ish?
 
183.5 HPs only if it came straight from japan and only had 25,000km. If it had more, substantially less HPs. If you got one with an adjustable power band, you should be rockin' the high 190's of HPs if you play it right and only use JDM gaskets and JDM axles.

I have that exazckt same setup. It's so JDM it's off the chain y0.



Or maybe you'll figure out that you won't gain more than roughly 10hp with those mods. If you want to play, you gotta pay. Turbo or n/a build it or don't expect miracles; your choice.
 
damn 183 seems mad high for a NA d series, what do you mean adjustible power band?
 
not 130 with my bolt ons and a factory 135 hp rating
 
wheres that at, but its not a big deal on my numbers just curious im doin a b series swap in the near future
 
Any of the tuning facilities in your area- look for shops that do general tune-ups. Many of them will have a dyno. I thought Kwik-Kar was a national chain. I guess not.
 
You could just paypal me the money you're gonna spend on all that crap for your zc. I'll make you a really professional and real looking dyno printout. Then when you swap to a different family engine, you don't have all that crap in your garage gathering dust.

Chris is right. You wind up losing torque and thus power with a lot of "bolt ons".


If you really want tunability in your engine, get one of these:
Adjustable Powerband - $249.95 : KaleCoAuto, Hard to find automotive items!
 
^LOL
That site brings back so many memories and good times in high school hahahaha
 
i have the same in my new rex. single cam zc cai,h/e fresh from Hmotors about 30k miles. im guessing low 140. what trans u got?
 
The ZC you have is probably the one similar to the D16Z6. With bolt-ons, probably putting down around 110-115whp tops.
 
All my stuff came from an eg vti. not exactly sure what the difference is but i use parts from eg Si. (z6)
