Oh, my bad vsiev.
Guys, you only have to worry if you're in California really (I think they're the only ones who do visual) Also, I think that the RB26DETT is legal now, ever since MotoRex started importing, of course you'd have to do the same modifications they do, but they state that they do not detune the motors, but only add all that emissions garbage... If that's true, then there you have it... a fully CARB legal swap for you power hungry boys. Those Skylines must be registered as California cars when they're imported right? Which means the RB engine has to be in the SMOG book to get tested... One of these days I'll call up a referee and bug him about this, if I ever get the # :P
