sr20det timing...

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 :))

The left cam gear is off, the dot should be in the middle of a link. Where are the gold chain links??

hrrm, i dont recall seeing any gold links.

they are both supposed to be in the center of the gold links

so how can you set this up if you dont have those marks on your chain… ive been trial and erroring it for a bit now.

im guessing without taking the front plate off, theres no real way to get the timing chain around so that the gold/silver links will be in the correct place

The cam timing links are a dark grey or black. The only gold link is the one that lines up with the crank gear. If you installed a new chain you should do it with the timing cover off. Its alot easier. Keep turning the crank until all the links line up. It might take a while though. :slight_smile:
