p28 or p72

[mdpc20653]

hi,
which to get i have an h22a4. which will be more beneficial? i'm thinking the p72 for the secondary runners (IAB) and knock sensor. which the p28 does not. where could i get a p72 for a good price?

oh i have a 2001 prelude and i want to switch from obd2a to obd1. for better future possibilites and tuning.

oh and is there anywhere around to getting the iab to work with the p28?
