It's about time for my first proper service since I bought my 91 EG.
I don't know a lot about cars, but here's what I was told about the car.
jdm b16A
type r manifold and throttle body
type r headers
red type r rocker cover
trust comtec ice box
racing timing belt and water pump done 15000kms ago

dc2r suspension front and rear
type r front breaks with blue calipers, dc2 rear brakes
front rda 400 discs

This is my first car, and will be my first real service which i plan to do myself. So just after a bit of advice on what I should be doing/using.

Oil & Filter - I have a spare filter, but what oil would you recommend?

Water - Should I flush the system and replace with new water / coolant? Is there any particular brand coolant I should be using?
Is this as straight forward as pulling the plug, flushing with water, draining and refilling with water/coolant?

Air filter - It has a 'comptech sport' air filter. Same as pictured here:

Should this be replaced?

Tyres - I keep an eye on pressure fairly regularly. Should I rotate the tyres...?

I guess that's all the basic things I should be doing?
Is there anything else you would recommend? I'm keen to do a little bit more than necessary, just for a bit of learning / experience. At least I'll know a little more about my car if I give it a good service.

I was told it may be a good idea to replace the spark plugs and leads. Should I be doing this too? What plugs and leads would you suggest?
Should I also be checking or replacing the battery?


Sorry for the million questions, but I just want to do a thorough job and not screw anything up.
Thanks for any advice guys, I appreciate it.
