Checking timing

Hey guys sorry bit of a noob question but am i suppose to take the timing belt cover off that the cas is attached to to check timing with a timing light? I can see the marks on the pulley but not the ones that are on the belt.

No you check on the harmo. Please Google a how to for a nice illustration on what you should be doing.

You are confusing ignition timing (when the spark plug fires) with cam/valve timing (when the valves open). If google isn't your friend now, it soon will be.

 You will need a timing light to start with.  I prefer the ones that take batteries.....no induced signal from the car battery that way.  But I use mine on lots of different vehicles including motorbikes, so others will have other opinions on that.  Plus the R33's have the battery in the boot so.....hard to use one that doesn't have its own power anyway.

Most youtube clips show the ones that hook up to your cars battery.

Car has to be warm and idling at 650 rpm, every mark is 5 degrees, you need to be at the 4th mark [three gaps] for RB25, 5th mark for GTR, [check the sticker on your bonnet, should have the degrees you need], loosen the three bolts holding the CAS and turn this to adjust the timing - only loosen as much as you need, it shouldn't be flopping.  Turn off car, tighten bolts on CAS, start car and check. Kick back and have a beer!!! 

Long version............google or youtube.

Sorry but there are 2 terminals at the fuse box under the bonnet that one uses to jump start the car/ hook things up that need power....

And if you have an aftermarket ECU enable the timing lock so the timing does fluctuate at all trying to control the idle, etc.

I prefer to always hit the timing lock then hold the revs about 3000rpm then adjust the CAS, however if you have a stock ECU just ignore what I said and follow the instructions from Nissan.

Ha, never looked, never needed to cos my timing light has its own battery source.
