if you are runing below 400bhp you can leve out the rods if you want, but i'm the sort of person that will only do the job the right way that way i only do it the once.
are you going to do the topend as well?
hope this helps but it will be cheaper to get one form bobby (or who ever) thats all ready been done.
ps if you get rods make sure that there for the pulsar not the 200sx as they use diferent size bigend bearings, but you probably knew that.
