Car looks sweet man. I had a CA20 R31 man piece of puss admittedly a heavy car to heavy for a 4 cylinder in my opinion. Now i have also seen 3 cases where Ca20's have put a piston through the block 1 in an R31 like mine and the other 2 in series 3 bluebird's and the cause was someone trying to put the foot down for simple reasons such as overtaking,going up a hill. Mechanics and other car enthusiasts tell me they have piss weak conrods and i take there word especially when you see the damage. All said may be a different story in a 1200 but i wouldnt bother.
