im looking to add some bolt ons to my rb25det neo like intake manifold and top mount turbo manifold but am having trouble finding parts online . will normal rb25det parts such as these fit on my neo motor ?

it depends on what part it is. for intake manifold, greddy and "freddy" manifolds will work with some minor adjusments: one of the studs isn't correct length, the dipstick tube hits the manifold, and the vacuum tube behind the timing cover needs to be cut or modified. also the aac valve will need an adapter if you plan on keeping it. then injector adapters & fuel rail adapters if you keep stock rail and injectors, if not then aftermarket stuff should work. the exhaust side should be no problem.
