Get a vehicle registration number
DVLA uses a points system to decide what registration number to give a radically altered vehicle.
Keep the original registration number
Your vehicle must have 8 or more points from the table below if you want to keep the original registration number. 5 of these points must come from having the original or new and unmodified chassis, monocoque bodyshell or frame.
Part Points
Chassis, monocoque bodyshell (body and chassis as one unit) or frame - original or new and unmodified (direct from manufacturer) 5
Suspension (front and back) - original 2
Axles (both) - original 2
Transmission - original 2
Steering assembly - original 2
Engine - original 1
You need 8 points to keep the original registration, so changing the engine and box loses you 3 points leaving you 11 providing you don't modify the bodyshell. Brakes are free providing you keep the original axles. You just have to MOT it because of the engine change.
