Nice one mate, I even understood a lot of it, ha! Amazing thing is, the more money you spend the more money you have to spend I have already out-modded stuff. So, if I add a bigger turbo, I'm looking at a gearbox and clutch on top of the price of the turbo, plus an oil cooler and most likely injectors, pffff puts me out of the running for a while!
Hope you get all your niggles sorted and have your car in tip-top running order The only thing you never mentioned was a 2.5 upgrade... tempted?
