hey everyone
need an answer asap
just wounder if the grades for the pistons 1,2,3 are the same for both engines eg stage 2 pistons for 1,3 same as 1.0l

yes mate, pressfit (2" thou interference fit iirc) i,ve used a jig to remove my CG ones (in the pic) but had to use a different type of jig for the oval skirted CGA ones (covered in my blog somewhere)

and if you use a CGA crank you get a bit of protrusion
