just looking from some opinion's on what pistons i should poss run in my turbo build. i have being looking at poss running a set up kinda like this; rb26dett pistons rb26dett rods rb30e crank etc and havnt quite got as far as the oil pump side yet. the reason of using the 26dett rods is because i will poss need to lower compression so have thought i could poss do that with the shorter rods and pistons (if they are shorter cos i dono) is it poss to use this set up with a "normal" head gasket and have the compression lowered and be all good to boost up?
