I am actually about to start prepping myself a new engine to slap a turbo on. The bottom end will be based on a 1.8L 16V block, as shorter-throw engines spin up faster, allowing the turbo to spool faster. Compression ratio will be in the area of 7.5:1 or 8:1, with ~15 lbs of boost. Should be more than enough to make about 250 wheel horsepower.
