Wsup zilvia, just to let you guys know in advanced just in case people want to put me on blast or something. I was wondering if it was legal in california and the US to swap out a sohc ka24 from your 89-90 240sx with a dohc ka24 from a newer year? One of my friends said that it won't pass smog. I was also wondering if it was legal or illegal to do a 5speed swap on an auto 240sx? My other friend said that it might not be legal to do so due to emmisions. Thanks, let me know.
