I just put my obd0 dohc zc black top motor i'm running a pr4 and I have no check engine light I'm have 87 octane in it for now till I burn it off the motor runs great but feels like i have sohc no ***** at all any ideas?

 

Bump if viewed please

 

Going to need WAY more info then that to help you....

but... I will tell you now that motor is by no means fast. should have a little pep v-tec crossover should be pretty good, however it is not "fast."

just my two cents.

 

I seriously feel like a stock ef si could beat me before this I had soh zc and before tha. Had a d15b so I have an idea what the power should be like it doesn't get off the line for **** I was thinking of getting new plugs wires cap and rotor

The flaws right now are u have stock exhaust manifold and exhaust I need to bump it up to 2 1/4 and start running atleast 91

 

having driven BOTH those motors I know what your saying bump up 91 and have fun. if your CEL free its just how it is. I run a b16a header and intake, and still not happy. hahahaha thats life in a honda always want more

 

Yea man I'm just glad it's running now I'm going to start on the tune up unfortunately the exhaust will have to wait for now I'm trying to get a build thread I have some good pics but I have been having problems uploading pics

 

I definately need the tune up **** forsure

 

I'd say just do that tune up run synthetic oil, and stay above 5 k. every v-tec motor from honda is at least kinda quick above that.

 

Why do you keep saying vtec I'm non vtec? And I'm not believer in synthetic maybe if I built the motor

 

Lol plus I have a dx cluster no tach so I have to guess rpms by ear

 

It's offical I ran my buddy's 89 si sohc zc vs my 91 dx dohc zc with si trans and he spanked me somethings not right

 

It would be a good idea to give us more information if you really want help.

 

Seriously dude there's plenty there obd0 dohc zc everything is wired right no check engine has fresh clutch flywheel and si trans stock exhaust and I'm still burning what's left of my 87 octane will be running 91 once it's gone I have the used spark plugs cap wires and rotor for now

I have a major loss of power especially at low rpms kinda seems like it's missing

yes firing order is correct but your wellcome to send a pic

I'm runnin an obd0 pr4 ecu
I'm running rich but I hear that's very common for a dohc zc when you run American ecu's

new cam position sensor

idles perfect

revs all day

no
knocks clicks
anything like that

hopefully that's enough info it's basicly everything I already listed

 

try a throddle body positioin sensor

 

Highly doubt it's that but I have extra pm6 manifolds that I can take sensors off of I'll definately look into it if the tune up doesn't help

 

Tune up worked awsome runs great thanks all
