yeah I say the plenium looks really good I like it alot not what i was expecting.
consider the cams as a good option as sydney kid suggested you might even be able to got the 260 or 264's there are plenty of kw hidden in your current package no need to change turbo. an the 300 klms to 50 litres isnt that bad fuel economy.
sound like a good result now go to the tracka nd run a number
