sr20det timing...

[standXalone]

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 )

FRSPORTS have a pretty good guide on how to install cams...if you read thru it, you should see how its supposed to look and they even count out how many chain links it is from divot to divot.

Installing Tomei Poncams on S13 SR20DET

PS: Throw away the chain guide protector thing thats hanging over the top of the chain. All that things gonna do is drive you crazy when the chain taps off it. Also, I'm guessing you slapped a new chain and chain guide in there, how come you didnt just the chain marks to line things up? There should be links on the chain that corresponds with the position on the crank and the cam gear divots.

Mechanical timing looks good, after you lube cams and install the cam caps. Remember to rotate the cranks a few times by hand. This will release the chain tensioner and let you feel any funny business. Then just have a timing light ready for when the engine gets installed.
