DD i dont mean to argue the point with you but its all well and good what the RTA says but personal experience is that the RTA says one thing but getting VSCCS engineers to sign off on things is another ball game its there arse on the line and thats why and where there getting tougher. Best to ring around and do some personal enquiries hence why i said to contact member 25GTV he is up to speed on all the can and can nots.Brakes has become a crucial element in any conversion (A Good Thing). For example a lot of engineers i have consulted say if your running a CA18 you need to run the same brakes as the vehicle that engine came out of.
