JDM Dohc ZC timing
I put a turbo on my zc and it made my timing jump and i could only boost like 3 Psi and then i would get boost cut or something so i took the turbo off and went back to all motor and i was wonder if theres a picture anywhere it shows where the timing parks should be for the cam so i can put it back into time and go with the turbo again

If boosting made you jump timing, you need to replace your timing belt and the tensioner ASAP before you start bending valves. Thats your untuned ECU throwing a code for your MAP reading positve boost....Its designed to read +/- 2-3 psi, compensating for different altitude levels, but once your pass that the ECU relizes somethings fucky, throws a code, and puts yo *** in limp home mode. Thats why fuel management exists, cant boost on a stocky stock untuned ECU. Read more, post less.

I dunno, something is not right about that. How much tension does that belt have?

Re: JDM Dohc ZC timing
if it was tight to begin with, I'm still not seeing why boost would have cuased it to jump time. Are you running a tune or base map, or EBAY chip? Sounds like its reading boost from the stock MAP. You sure it jumped time, as in the arrows on the cam were not pointing the same way? I think of the ECU cutting power per positive boost reading from that discription. Off timing would run like *** regardless of RPM or boost. Especially at Idle.
