BD's Screamer turbos are drop-in units that look stock but move more air, with no big changes to the intake or exhaust. The L5P version starts with OEM housings machined for a larger 66.2 mm compressor wheel and a 67 mm turbine wheel.
BD rates the airflow at up to 80 lb/min, for lower EGTs without giving up low-end response. With supporting modifications BD says it can reach about 680 hp.
