I heard all kinds of stuff....I don't know what's up with it....


Like the car won't pass emissions....Right?...Why not?

I heard that in JDM engines they are ran on higher octain in Japan and if you run them on 91 they will create a ping....Is this true?

I can't even remember all the stuff I've heard to write it out....Can someone please shed some light?

JDM engines are so cheap and easy to get compaired to finding a USDM....

Thanks
