its a small turbo esc cos windage tray, needs the 2wd modifying to fit

aint no expert by any means but i understand the 4*4 manifold is ok at that power level....... i know of quite a few engines that have come off a dyno with a tad more hp that 400 whilst keeping a 4*4 manifold

the 4*4 manifold is supposed to be better for high torque at low rpm engines





personally id go with the 4*4 manifold if i was going to stop at around 400
