Precision Turbo 5831, includes adjustable boost actuator, journal bearing. The modern version of the TE44.
Entry level turbo, one step up from stock. Capable of about 585hp.
Works ok with the stock torque converter, but will spool faster with a higher stall converter (2800 or so).
This has a 3" inlet and you should use a metal inlet pipe with it, not the original soft hose.
