Thanks guys. It's a 2.0 Turbo BTCC edition that Vauxhall gave a handful to Triple Eight (888) to tinker with. They added those black bits on the front bumper and a rear diffuser. They have also meant to have upgraded the engine a little, from 175Bhp to 195Bhp. It has a different fuel rail to the other 2.0 Turbo Vectra's, and bigger injectors. I have noticed it needs new discs, might as well get the pads done also. I can hear a new noise from under the bonnet, I just hope it's not the timing chain. I might get it done while it's in getting the discs changed. I get paranoid about timing chains and new noises
