They use a k20 head to raise the compression, with a turbo that’s exactly what you don’t want, turbocharged engines have lower compression than a normally aspirated engine. The old book only shows two pistons for that engine an A piston and a B piston, those a both the piston size, so you need to measure the bore and buy the right pistons. Unless the block has been bored out then you only need the right oversized ones, no A or B. Hope that makes sense.
