We just finished up another RB25DET long block build for one of our customers. Running 9:1 CP pistons, Manley turbotuff rods, 262/262 cams, valve springs, bronze valve guides, ferrea intake and exhaust valves. Our good friends at performed the cylinder head machine work for us and did a great job. Running trigger kit, splash plates, adjustable VCT kit, pcv delete press in plug, rear head oil drain and rb25 extended sump kit with trap doors which we installed and welded onto the customers stock oil pan. Running the front head drain hose kit, CAS Bracket, billet halfmoons, and valve cover hardware kit. This should be a very fun ripper once the customer reinstall this engine into there S13.
