Jellybean Posted February 11, 2016 Share Posted February 11, 2016 Short Block Questions 1. To hone the block would you use a deck plate, with the gasket, to simulate the cylinder head bolts being distorted? 2. Would you line hone the 2JZ with the oil pump on it, to take into account for the distortion of the main caps? Cylinder head design Don’t quote me on this , from a bit of reading on here ; 2JZ head is not the most efficient head, if anything it is a limiting factor ; Yamaha was involved in the design? Considering an Engine is just a big pump to get the most air and fuel in there to create the most power , what can be done with a 2JZ head? We can swap out • Valve Guides • Valve springs • Valves • Cams Questions 1. Are heads optimised to flow up to the valve lift of the valves installed? 2. Are Valves and Cams tuned to suit the valve lift , the cam on a cycle will go through the mid lift number twice (Opening and closed); ideally you would want the head to be optimised to flow as best it can at this point ?
