I just need to clairfy, I could use the following in a series 1 / 2 engine ? :

Focus Rods + Focus Pistons + decomp plate ?

Is the standard series 1 / 2 engine a 85mm bore?, because that is what I see the piston size specified for the focus piston from america.

So would it be pointless me buying a block that has been bored out to 86mm as the pistons would be too small ?

Also, as I say, the block I was looking at has accralite pistons, and these would not work with the american rods from what people say here due to the small end of the rod being 19mm from ameerica and the accralite pistons would be 20mm, Presumablly standard rods would fit the accralite pistons?

Thanks again for your help.
