I understand that hondaswap probably doesn't have perfect information,but it is a good reference point.I have yet to see a motor that in 90-94 made 130hp make the same power 8-12 years later anyway.Wear and tear,I seriously doubt my siRII is still producing the 170 it started with in 93,but I don't have a dyno available.In order to achieve the original hp you generaly have to go inside and freshen up or replace internals.Even SCC's eg civic made around 130(if I am not mistaken with the dx exhaust).Even with the bolt ons I don't think it hit peak original numbers.All I am trying to say is hp figures contain so many variables that it is hard to tell someone that this is the motor you want cuz they could go buy a b18c5 that looks immmaculate on the outside but is suffering powerloss and they're wondering why Joe Schmoe's b16 is blowin him away.
