accessory zone sometimes have some in, Drmikey on here has usually got some in stock and is more than capeable of carrying out the conversion for you if he has time,,
don`t think anyone will accept the b16b as PX though,,
to shift the B16B try DMRR they stock all the mfactory transmission stuff for the rally boys and B16b`s are great for rally car transplants as they are high power 1.6`s
