What pistons do I need for a 1293 build. I am getting a quote for machining work and a rebuild of the short engine and poss gearbox from a local reputable Engineering Company but just want to make sure I know what I need to ensure that they follow suit
I believe I am aiming for a 10:1 CR and the 1293 will be a +20 rebore so needs matching pistons.
I have read several threads recommending the 21253 pistons and have found these on MiniSpares offering a 10.3:1, which are AE Hepolite Pistions, they also do an Evolution versions suggested as a higher compression ration at 9.73:1 here.
Any recommendations on what should be fitted and what CR I should be asking for?
