Sorry looked it up but battling a bit.
- What oil do you guys use in your skylines [ I tried Nulon 5W 40 seems ok ]
- Why would my baby slightly backfire after hard acselleration and suddenly letting go of the pedal, is this normal.
- Why would I have a strong negative camber on the wheels after going from 16'' wheels to 18'' wheels.
- Would this be a good or a bad thing to install...http://www.ebay.com.au/itm/Nissan-S..._Parts_Accessories&hash=item460c1a4180&_uhb=1

I use Fuchs Titan which used to be called silkolene pro r or s

The backfire is not easy to diagnose without more info but it definitely has nothing to do with the oil.
It is either an exhaust leak or more likely unburnt fuel which just needs a bit of tuning
Super pro bushes are worth fitting all round but there is a fair amount of work there especially if you do the subframe ones. Adjustable arms might be better as you can solve your camber issues much easier
On that subject what size are the current wheels and tyres

Thanx Sleeper, good man.
The oil is just for interest sake, got to do a service soon and thought I might try Mobil super 3000 X1 5W - 40.
My suspension very creaky and squeaky so I'm thinking worn bushes so I'm thinking why not do the whole lot using super pro bushes. Going to install coil overs soon as money available. Wich adjustable arms are you referring to? [ still learning ].
Had the stock 16'' rims on now running 18'' Lenso with 32 offset all round [ not correct but that's another long story ] and since I fitted the 18'' rims I have a very strong negative camber baffling me a bit.
The sparky told me the air flow meter seems fine and the timing is fine so now I'm wondering about the back firing. Oh it's 18'' X 9'' rims and 235 X 40 tyres.

Backfire on the overrun is probably as Gummy says, bit of unburnt fuel. These RB engines run quite rich. If it backfiring and hesitating under load when accelerting then plugs, coilpacks, afms etc all need investigating. Enjoy that Skyline smile :)
