:( I want to upgrade my Teg from the RS/GS engine to a B18C Type R engine, USDM or JDM, I have the money, but I am frozen in my tracks because of worries about emission problems. Any suggestions or info? Experienced knowledge extremely needed. :rolleyes:

I know everyone is so stuck on JDM being better because it does have advantages, but if your worried about emmissions it would most definitely be easier to go with USDM. now this is just what ive figured from what ive read about this.
