HKS Complete engine RB26DETT 3.0L STEP3 V-CAM

[Complete engine RB26DETT 3.0L STEP3 V-CAM] The pinnacle model of the RB26 complete engine.Newly developed 2-piece piston realizes increased stroke and connecting rod length while maintaining block height. The 3.0L dedicated crank is a full counter machined from nitriding steel, and ion nitriding treatment has increased the surface hardness to the limit and improved fatigue strength. In preparation for higher torque, a dedicated I-section connecting rod is used to improve buckling strength by 36%. In addition, we also adopted a φ22 thicker piston pin. As a countermeasure against the heat generated by the high power output, the valve guide and seat materials have been changed, and a sodium-filled EX valve and a piston with a cooling channel have been adopted. The 36-tooth dedicated crank angle sensor and crank angle sensor for V-CAM have improved signal accuracy in the high revolution range. *It is recommended to use HKS Racing Pro 10W50 engine oil. Dedicated full counter crank Dedicated I-beam connecting rod with 36% higher buckling strength and 6mm longer shaft distance Changed the valve seat to beryllium and the guide to phosphor bronze to improve the heat transfer performance of the valve. By making the piston two pieces and raising the pin position, it became possible to reduce the compression height. This made it possible to lengthen the connecting rod and increase the length of the rod without increasing the deck.In addition, the piston is super lightweight at 313g and has a cooling channel for oil cooling. 2-piece piston V CAM dedicated crank angle sensor 36-2 teeth IN side: V CAM STEP ProEX side: 280° STEP2Reinforced blow-by separator reduces oil take-out Specifications   HKS 3.0L(V-CAM) genuine boa 87.0mm 86.0mm stroke 84.0mm 73.7mm Compression ratio (t=1.2) 8.7 - Allowable rotation speed 9,000rpm 7,600rpm Displacement 2,996cc 2,568cc COMPLETE ENGINE RB26 3.0L STEP3 V-CAM camshaft IN：HKS V-CAM STEP Pro 264°／ LIFT 10mm EX：HKS STEP 2 280°／ LIFT 10mm blow-by separator IN/EX HKS reinforced product cam cover HKS RB30 only (EX side) cam pulley HKS SLIDE CAM-PULLEY (EX side) Timing belt HKS Fine Tune Timing Belt spring retainer HKS Titanium valve IN: Genuine　EX: 1mm big valve (filled with sodium) valve spring HKS reinforced product stem seal HKS reinforced product head processing Combustion chamber machining (remaining squish), Sheet: Beryllium/Guide: Phosphor bronze,Step removal and polishing around the sheet, Cam escape processing, Water jacket air vent hole processing head gasket HKS grommet super cooling type (t=1.2) head bolt HKS reinforced bolt Block (24U) processing details Surface grinding (parallelism correction with the main journal), water hole processing, deck surface hole chamfering (crack countermeasures),edge removal processing at the bottom end of the cylinder, boring oil pump HKS reinforced product piston HKS 2 piece machined connecting rod HKS I section axis distance: 127.5mm Crankshaft Nitriding steel machined full counter ion nitriding treatment main bearing ACL connecting rod bearing ACL crank angle sensor 36-2 tooth Crank direct attachment Ignition system HKS Super Fire Racing Coil PRO crank damper ATI 1000PS specificationW/P pulley: Φ124 (ATI)rib belt: 4PK850, 4PK910, 4PK925 covers baked paint finish
