A few months back, at the Datsun Nationals in Sydney.. I saw an A15 powered 1000 Coupe get 76kW (could have been 78) at the wheels. That's the same amount as my old CA18DET Which got 78rwkW ...We all agree now that there was something wrong with my old CA. But that fellas 1000 was an inspiration. It really made some noise on the dyno..very cool.

if my calculations are correct due to cam duration and compression i should have 132HP at the fly

ya gonna tell us about the motor rally-a-coupe or ya just gonna leave us wondering

10.1:1 compression ratio .ported head ,doubble valve springs ,wild cam should make power between 4500rpm to 9000rpm,lightend flywheel ,balenced bottom end ,A14 pistons,twin 40 ml dellorto's ,extractors

sounds kinda like my motor, except the 1400 bit, so all i gotta do is build an a-12 block with a-14 gear to get an extra 32Hp, sounds good to me

use of a-12 block is to comply with rally rules

A14 pistons give you close to 1300cc

yeah but can i use the a-14 crank to achieve 1400???

To use the A-14 crank, you'll have to find shorter connecting rods. If you don't, the pistons will pop out of the top of the bores. Or crash into the head, if you got that far before turning the crank during the build!
They, Nissan, raised the deck height when they "stroked" the engine.

Are custom pistons with higher wrist pin locations available?

The A10 rods are shorter than the A14 rods ...
