build the 434
the torque of the large engine will do wonders to hide the turbo lag
limit RPM to about 5500-6000 max on the street and size to turbo to fit the
the application
you are probably looking for ~500 HP so find a trubo that can produce enough
airflow to make the 500-600 HP range and install it to spool up fast
