Cheers John, your replies are always quick and full of info! If I can't find good gas then I will only put enough in to get me where I am going. I don't think it is full OBDII (in the UK I dont think it was implemented fully) but it is a 1998 car, so I can read codes using my peake code reader. It has knock sensors which is the main thing though I guess. Nice to hear that other people have done the 3.4 pulley! Good thing about these engines is that if they blow you can pick another up for £200, whereas a M3 (euro) engine is mega bucks! __________________ Supercharged 318Ti |
