Re: H22A cam timing degree wheel
ya your definitely in a pickle with this one, bone is right, you need the diameter of your cam gear and preferably the tooth count on the gear, the actual tooth, not the raised portion between the teeth, divide the tooth count by 360 (360 degrees in a circle) and you come up with the degrees per tooth. Also if you have an accurate vernier near by, you can measure the tooth width on either the gear or the belt, take your tooth width in inches and divide that by your degree per tooth figure. you'll end up with a figure that shows how many degrees per thousands of on an inch for each tooth. Take your milling total and divide that by the degree per thousands of an inch figure you got previously. That should give you amount of degrees you are off for your cams, advance the gears accordingly. I'm pretty sure this is right, but I could be wrong, someone correct me if I am

Re: H22A cam timing degree wheel
DUDE thats the best and most logical info I have ever recieved on anything dealing with my motor. 1, put the motor TDC, 2 count the lower portion teeth on the cam gears, 3 measure the distance on center of the lower portion of the teeth and divide by 360' to find how many degree's per tooth, 
4 then what do I do to set them in when I'm ready to reinstall the BELT. As a reminder this is a H22A in a 93 civic hatch and the room between the timing cover and the strut tower is like 1.5 inches. THANKS GUYS/GIRLs

Re: H22A cam timing degree wheel
This is some more info I rescent recieved, My head was also milled before I done anything with it, "says my machinist" Only way to get accurate count of how much was taken off was to get a O.E. stock nonmolested head and measure from the top to the bottom. GEEZE anyone live in or REALLY NEAR Seymour Indiana, which is 60 miles north of Louisville KY and or 60 miles south of Indianapolis Indiana that would love to lend a helping hand.

i think i am haveing the same problem as the OP. i have a gsr with 11.8:1 compression pistons and it's a pretty fresh build, would say not more then 1000 miles on it. has a port/polished head and was milled .040, with all upgraded vailvetrain and some rockett M24 cams. some reason it doesn't feel strong as it did with the old head. my cam gears are at 0 0. so if i'm understanding you correctly need to advance the cam gears "about" 4 degrees a piece? maybe i'll reread your post and it might make sence.
oh and i did a compression test before but did it wrong, lol. i had forgotten to hold the TB wide open so the results went from 195 on #1, 185, 175, and 170 on #4. so i'm thinking i should redo it lol.

Re: H22A cam timing degree wheel
if you have a compression tester handy you can do what i normally do. pull the #1 plug and turn the engine over with the dist disconneted. keep advancing the cam gear until you don't see a gain in compression anymore. then reset your ignition timing and go for a ride. sometimes this is a decent street tune. this only works on NA motors btw..

Re: H22A cam timing degree wheel
WHOOOO ------ HOOOOOOOOOOOOO. I advanced the intake and exhaust cam 1 tooth and retarded the gear 2 degrees, and hooked the crank/cam wheel with the depthgauge on the retainer and everything matched up PERFECTLY. I let it run for about 10 min and killed it and popped the top of the intake manifold and BEHOLD no rivers of fuel. This was with the hondata S300 set on the P28 fuel map with the H22A timing and it ran sexy at a A/F of 14.5 on the wideband so I drove it around the block"first time since May 06" and it never got lean but I didnt take it over 3 grand. So I pushed my luck more and hooked the P13 factory ECU and rewired the stock 4 wire O2 back up and started it and it ran ruff for about 30 seconds till I noticed that I forgot to hook up the IAC. I killed it again and hooked that up and started it and it purred at a nice 750rpm, bad part was is that piston slap is there from the Ross pistons waitn to heat up. I drove it around the block 3 times and pulled back into the shop and it sounded like OEM. No knock/piston slap, and NO CEL's. THANKS GUYS I learned alot from you once again.
