By having the spark plug fire a couple of degrees sooner, you give the mixture more time to burn, thus burning more completely, thus releasing more energy, thus creating more power. One of the limiting factors in how much advance you can use is knock. This is one of the places octane comes into play. Lower octane fuels burn more quickly and limit the amount of advance you can dial in. But our motors are designed to run regular 87 octane, and since 17 degrees is within spec for the motor, you shouldn't need to go to higher octane, unless you've done something else to the motor like running higher compression.
from sr20de list.

I read the sr20de.net webpage and have a few questions. Firstly, what do you attach the timing light to?
2) When they refer to the distributor cap, do they mean the black thing that all the HT Leads plug into? 3) Where are the timing marks they talk about? Help appreciated.

[b]Firstly, what do you attach the timing light to? The positive and the Negative of the battery and the no. 1 plug lead. 2) When they refer to the distributor cap, do they mean the black thing that all the HT Leads plug into? Yes 3) Where are the timing marks they talk about? They are on one of the pulley wheels (the ones with all the belts attached to them) down on the left side of the engine. I think, if you're looking from straight above, that they are on the middle wheel. On mine i remember they were like nicks in the side of the wheel. Hope this helps.

So how DO you really advance timing? What do you need to adjust?

It is done by slackening the distributer clamping bolt and rotating the distributor housing. There are other things as well like disconnecting the TPS etc so find yourself a good procedure.

the actual distributor cap moves back and forth when you LOOSEN the nuts holding it to the block. you should find these nuts by seeing they can slide either way. im not sure which way is to advance or retard but thats what you have to do.

Thanks for that info. Now does anyone know where I can get myself one of these timing lights and how much they are.
I had a look at the black distributor cap. Im still not sure which bolts to undo to advance the timing. I understand that if I rotate it towards the front of the car the timing is advanced. There are two bolts on either side of the black cap. I can loosen these but the cap doesnt rotate at all. Another question. What to you actually use the timing marks on the belt for?

Not on the cap .... on the aluminium distributor housing base flange where it attaches to the head. Tell you what, go to the library and find the Haynes Nissan Primera service manual (book # 1851). It has everything you need to know in it. If you buy a timing light it may come with instructions on how to use it.
EDIT: If you're coming to Hamilton for the motor show this weekend I can show you how to do it.
