I have a b18a1 and I'm wanting to bolt up a b16 si head. I'm looking for a n/a build of about 250hp. So, my ??? is what would be the best pistons and head setup for the ls block to achieve something like this, and is this a real difficult swap to put in a 93 eg8. Im not too familiar with double cam swaps only have messed with single cam. Good advice will be appreciated.
