Si is right, google is the way forward!
google courtenay sport, regal autosport (although i wouldn't) and thorney motorsport. There is another VXR tuner out there but I can't remember who they are, helpful I know....
I was gonna suggest Courtenay Sport as they're the only Vauxhall people I've heard off... my mate had a 2.0 Courtenay Sport conversion in his Nova... I never went for a ride in it by the way... but it was bloody quick! aperbag:
