The way I do it is;

Find TDC using a dti down no. 4 plug hole

Mark the position of the crank pulley or flywheel at TDC with a fixed pointer of some description.

Remove inlet cam cover

Set up dti on one of no. 4s lifters. You'll need a fairly thin extension on the dti to get it positioned square onto the lifter.

Wind the engine over whilst watching the dial and set the clock to zero when the valve is shut.

Wind the engine over to TDC and check on the dti how much lift you have.

Adjust timing to your desired values. I believe a factory engine with and un-skimmed block and head can handle around 1.2mm of lift at TDC but don't take that as gospel! There is no set safe amount an engine can be advanced. What works on one engine may f*ck another engine if its been skimmed etc.

Once you've made your adjustment check then re-check it! I like to only wind the engine clockwise whilst setting and checking.

Repeat for the exhaust cam bearing in mind that advancing the exhaust cam will give less lift at TDC.


This is only a very rough guide on how I do it, there's f*ck all room for error on these engines so be warned! I would never attempt to advance the timing without a dti, oh and it goes without saying but please don't come crying to me when you've got a six speed sewing machine :-D

I just advanced my inlet cam by about 3 degrees this morning. After a lengthy road test it didn't feel faster to start with as the cam 'kick' it gone, buy after a bit I realised it was just smoother with much more pull from 2.5k upwards.

Am on my iPhone now but I'll put a pic up of the inlet cam soon

Here's mine as an example of how much they were advanced, seen by the difference between the original bolt (marked around with tippex) and the new position

Inner pulley should be further clockwise than the outer pulley.

Email me!
Custom-made polybushes available - need an odd size or fitment? - anything from batch work to one-off pieces.

in the 2 pics above it looks that there both advanced, just the different type pulleys, assuming the crank is set correct then the cams are advanced on it...

IF YOU CAN READ THIS IM STILL IN 5TH!!!

Id add that mine is uneven on tickover and smells like its running a bit rich ....... if youve got that then you are probably doing it right

Lots of Nissans, two 306 GTI-6's. They are catching up!

Does the type of fuel you are using play a factor in how much you should advance the timing by?

It's completey standard. Wasn't sure if using higher octance fuel (V Power in my case) could affect the timing and how much it should or shouldn't be advanced by
