[95_rb240]

ok guys so i recently acquired an s14 with an rb25det. motor is basically stock and im still learning about the rb. well to make this quick i was wondering if i could get a few tips on what mods to start with. ive been reading that the stock turbo is one of the weakest points of the motor as well as the crappy intake manifold. would these be good items to swap out for aftermarket parts. i just installed a brand new spec clutch, new oil pan, iridium spark plugs, new starter and belts, new motor mounts. these were all necessary parts to switch out thanks to the dumbass owner before me who abused the car.

any input will help guys. my hp goals are somewhere around 350hp-400hp
