To help reduce any chance of boost-induced valve float and to improve thermal heat transfer to the valve seat, we switched valve springs to the nearly 50% stiffer OEM parts found on the MR16DDT engine. These drop right into the stock head and are compatible with the stock cams.
With our parts all together, stay tuned as we assemble our engine and design our turbo system!
