2.3 or 1.2?
 

On my v5 slip from the DVLA, it states that my "1985 RX7 II" is 2300cc, yet i thought it was 573cc x 2, which makes it 1146cc

Was there a special edition "Big-Bastard" 12a, or have DVLA just head-fucked themselves?

I've only just realised this since I got bored and looked at my v5 slip!!!
