tyres are expensive $247 each just put two on the rear. it was a bit taily for my liking. will put another two on in a few weeks but i do like white paint out. as for the v6 i just took my injecters out and got them cleaned. dont be fooled the only way to properly clean injectors is to take them out and get them done at a injector service place. the difference is unbelivable. prick of a job as you have to pull off the inlet plennum. also replaced spark plugs make sure you only put platnum plugs back in not like the previous owner of my d22. now she runs as smooth as silk. plugs $21 each at super cheap auto repco $27 each and trade price at aussie auto $18 each. unshure about cleaning injectors i think around $20 each i didnt pay its good to have mates in the busniss.
