I built mine, 11.7:1, flat face valves, and .027" HG with these cams. I have yet to start it, I finally pulled it to take it to a local shop that is now sponosring the car, they are gonna find out what is wrong with it.

My car threw no codes at all on my Kpro also. I did have it start on the third try, it ran like shit for 5 minutes, then got to 245* and I shut it off, then after 3-4 minutes I heard a pressure release from back of block, then nothing. I cant get car to start again. I did a compression check, which I recommend you doing, #1 and 4 were 40psi, and #2 and 3 were 65psi, oil in the cylinders bumped all 4 exactly 25psi higher.

Also, what is your valve lash set at? Specs say intake at .006" and exhaust at .008". I would check the clearances, if too tight your car wont start cause valves wont close properly to build compression. Also, try setting them loose like .008" In and .010" Ex to just run the cams in, then go back and tighten them to specs. That way you know they are opening/clsing correctly.

All else fails, talk with your shop again, which hopefully you are doing already anyways, I bet they are willing to help.

I called Brian Crower just now and spoke to them, they said if you stay below 11.5:1 on the stage 3s you can go full 50* advance and be fine on p2v clearances, over that 40*and then clay it to see if you can go more advance on them.

I dont think you would make power over 30* myself, you need compression to make them come to life. I think kevin949 on CRSX made maybe 5whp more up top on them than the stage 2s, and downlow the stage 2s made more hp/trq.

I would not see why it would be an issue for p2v clearance with stock pistons vs not having any with aftermarket. There is very little dome, higher compression pistons have more dome, to make it a tighter tolerance with p2v. Just how I see it, though I dont fully understand all that anyways.



Also, you said you had no compression, what psi numbers did you get? Did you try adding like a capful or two of oil into each cylinder to do a wet test? pour it down the spark plug hole. Afterwards do a compression test on that, if the number goes up, it can be rings or hg. If nothing, might be valves bent. Do you have access to do a leak down test? December issue of Honda Tuning mag had an article of how to make your own if you cant borrow or buy one. What does your oil look like, milky or just oily?
