Precision built using all of Cosworth's years of motorsports expertise and some of the finest parts available. Each long block starts with a Subaru OEM block that is diamond honed to exacting dimensions and fitted with a Subaru forged crank (billet crankshaft optional), Cosworth H-beam rods, Cosworth forged pistons, and tri-metal bearings. Then Cosworth bolts on a set of their CNC "big port" heads using a set of 11mm head studs and Cosworth high performance head gaskets. Cosworth's S2 high lift camshafts are responsible for opening the valves and a blueprinted high pressure oil pump keeps everything lubricated.
