on sentra.net, there is mention of swapping the brakes to those from an NX (1991 to 1993 chassis .. which would be a B13.. or was it B14 to B13 swapp?? i m not sure) to get bigger rotors and calipers.. and also something about swapping the drums to discs on the back end as well.. anyone know if that applies to an '89 Pulsar XE?? also had read about swaiping the suspension somponents from a B13 SE-R to a B12 sentra.. would this work as well on a Pulsar? it is my understanding the suspensions are the same from sentra-pulsar.. anyone can confir/deny this?
