hey guys, I have been doing some searching for several days now, and have followed the FSM to a T, but im not completely sure exactly if I have the timing set correctly on the sr20 engine. Im in the middle of a rebuild, franticly trying to finish it before i move to Edmonton, i only have a few days left!

So far, I got my new head, I rebuilt it all, new springs, cam brackets, cams, camgears, new metal headgasket, redecked the head and the block. Followed the FSM step by step, all proper torque specs etc. So i installed all that, got the head onto the block, and set the inakte camshaft key to about 12 o'clock, and the exhaust camshaft key to around 10 o'clock. I then made sure that the crank pulley was set and TDC and on the second mark from the left. I did some checking, and it looked like i was advanced one tooth on the camgears, then made sure that the valves on either the intake and exhaust were opening and closing in the same ratio. I also made sure that the first cylinder was at the very top of it's compression stroke while the crank pulley was set to TDC. I haven't installed the TCT yet or the CAS, only because i want to make sure the timing is set properly.

Now, what other things do I have to look out for here? Now that i have everything somewhat apart, i dont want to do risk not getting the timing right, and messing something up when i get it dropped back into my car. here are a few pics

If anyone can shed some light on this as soon as possible, it would be greatly appreciated.

(ps, i know the engine is filthy, I will address that once it is assembled

)
