More opinions needed.
RB26 running all bolt on gear. Current power figure of 342kw atw. Next step for me is cams, cam gears and valve springs. Maybe head work but for the point of this exercise we will leave this part out. Looking at Kelford items but need a little guidance. Pretty laggy atm and want boost to come on quicker. Was thinking 280 inlet and exhaust with spec card below:
