A10 stroke is 59mm so the rods must be really short. They could mayb be too short unless using a custom piston and also the a10 rods Ive read somewhere are forged and cheap for low compression alternative when fitted on turboed a12s.

what compression can we expect in a A12 with A10 rods?

Can someone answer my question simply

yeah or ney?

simply probably no. the crank may not clear the bottom of the cylinder skirts and the shorter rods may put the pistons too close to the counterweights.

So by slapping a14 pistons onto a12 crank and rods, giving effectily 1300cc, with a shaved head, extractors and either a 32/36 dgv or dual carbs, and possibly and electronic ignition kit, t would be feasible and cost effective for approx 100 hp, and depending on tuning, even at the wheels.

theres a lot of difference between 100 flywheel hp and 100 rear wheel hp (about 20-25hp). a lighten and balance wouldnt hurt while your at it. it will make it smoother and rev easer and freer.

very easy and cheap to get 100hp at fly from a-15!

yeah i know that the datto 1200sss in NZ has 89hp std

I spoke with my datsun sense and he said an a-12 is capible of 130hp at the flywheel but he asked why bother you can easily get the power out of an a-15 and have a more reliable engine to boot. to quote him "the candle that glows twice as bright lasts half as long"


thank you sense

yes but this aussie idiot says, the candle that burn twice as bright has twice the fun.
