Okay here is my question. Are 99-up JDM B20Bs you know the one with the LS type Intake manifold the same as 99-up B20Zs in terms of compression & power wise, becuase some JDM dealers have B20Bs for about $750 and, I found junkyards with B20Zs for about $900-$950. I would rather the most powerful motor stock between the 2 because I plan on building it up NA, but due to lack of $$$ I will be running around with just bolt ons for a while and need some type of power in that time period too.
