ok if someone is converting d15 to b16 which parts will stay the same(talking about aftermarket parts such as intake, exhaust)? and which parts are different? thanx..

 

you should change it all out. b16 needs to breathe more.

 

if you have an exhaust system already that should work with the b16 since it was most likely oversized for the d15. also an intake will work if you follow the same concept

too big for a d15 will probably be just right for a b16.

anything but intake and exhaust wont work
