Crawford Performance Billet Power Block
$399.00 On sale
CNC machined from Billet 6061 aluminum, Crawford's BPB sandwich between the cylinder heads and the intake manifold to create longer intake runners. The lengthened intake runners enhance the volumetric efficiency of the engine which translated into an increase of 19 Horse Power, 15 Pound Feet of Torque and narrowed up the torque dip by 300RPM on a totally stock BRZ. Their BPB also works with any aftermarket tune, exhaust and intake components. Crawford's original road testing was done in conjunction with their stage 1 reflash followed by extensive dyno testing with and without a tune.
Crawford's BPB kit consists of 23 pieces that make it a complete bolt on system which can be installed in under 30 min. In the kit you will find 2 BPB, 4 Delrin O-rings, 11 mounting bolts, 1 nut, 4 fuel rail shield risers, and 1 support bracket for the direct injection control unit.
Free OFT tune is available
