I thought about the guidelines but then I alone can't set guide lines, would be good if Harry (L18_B110) was here coz he knows what the guidelines are in Sprints and and Circuit Racing, (I have seen him race he's not bad at all...hehehe ) anyways, I was thinking of Improved Production Class in the Under 2 litre, the motor has be the same make as the vehicle eg... Datsun and Nissan from A12 to A15, L16 to L20, Z18, CA18, FJ20 and SR20 and it can be turbocharged but then you are up against the sixes and V8 brigades, it doesn't matter however. No matter what class we pick its still a challenge.
