Thanks for your comments guys
I have read a few threads on the problem with piston ring falure and was warned about it by maximum Motorsport ... My car is always run on BP ultimate 98 and I am using castrol edge titanium 5W-30 a3/b4
So far so good No knocking noises , loss of power or smoke etc.. My plan was a cold air intake , exhaust , and tune... The car already has a after market exhaust on it but doesn't really have that deep throaty tone yet... I suspect is some form of tuned by sti exhaust ... or similar provided by the dealer
Can anybody suggest a workshop that where happy with and what kind of costs I would be up for and what kind of power gain I can espect and if there is any significate difference between verso and ekutek ?
