Ok, I have all the parts right now and don't know if I should assemble and drop in now, or wait till I get Hondata or a VAFC. I want to be able to run on my stock ECU for awhile without any major difficulties. It's in a 94 Si and with my slightly built head- port.polished, milled .020, and ZEX cam. Can I reliably drive this on the daily and even 4 hours at a time and be fine for awhile> I was thinking so, but as far as reeping full potential, I'll need Hondata/VAFC and get my stuff tuned. Should be a little over 12 to 1. Might just need to retard my timing a little and run a conservatively. Get back

 

I think he meant p29's in a d16z6 block. What kind of timing is needed for this 12:1 CR?
