Just some extra info, the Family 2 blocks in the pulsars had a different bell housing pattern to match with the Nissan gearbox in the car. A friend was going to drop a 2litre Camira engine into his N13 Pulsar, but ran into this problem. He could have swapped the 2 litre crank & rods in, but didn't want to go to that much trouble. Crow Cams also had some grinds to suit the engine with some valve springs at one stage. This engine was revised & a twin cam 16 valve head created by Cosworth Engineering for Vauxhall, & was used in the 2 litre Cavalier race cars, & turbo charged in the Calibra. Would it be possible to get the 1.8 Pulsar block with the 2 litre crank & the DOHC cam head & drop it into a 1200. Easier to just fit an SR20DE.
