ZC Swap
I just made a ZC SOHC swap into my Honda Civic 94 LX 5-speed. The car has
now absolutely no low-end power even for a civic. My car stalls going up my driveway on first unless I slip on the clutch at 3000RPM. I have tested the engine compression and it is good and well whithin specifications. I have checked the timing and it is right at 15 degrees BTDC. Is there something I am missing? Thanks for any help in advance, - JR |
Re: ZC Swap
Did you install some sort of "racing" clutch?

Symptom: Hesitation, stalling at low end, runs terrible until completely warmed up, and even then no power. 'Curly' ================= -- |

Re: ZC Swap
I installed a new clutch yes. But I got it from the Honda dealer... no
"racing" clutch, just the stock... the old one was slipping. - JR "Jafir Elkurd" <jafir@nospam.no.spam.hotpop.com> wrote in message news:1036rsktjumb1bf@corp.supernews.com... > Did you install some sort of "racing" clutch? > > "JR Lomas" <jrl@engineer.nu> wrote in message > news:T7Odnc9bhsK8p67dRVn-tA@comcast.com... > > I just made a ZC SOHC swap into my Honda Civic 94 LX 5-speed.

Re: ZC Swap
The belt is not off by a tooth or two. I already have made sure of that, I
precisely aligned the marks on the sprockets. The car does not hesitate or run bad while cold (feels like it has more power when cold), the car has plenty of power once it gets passed 3000RPMs. "'Curly Q.

Initial timing being low could kill initial low-end power. **Caution**Initial timing being HIGH could burn a piston in a heartbeat! HTH & good luck. s |
