My 7m has a major rod knock, and im definatly thinking about a 1j. I am looking on ebay, what should i look out for/ ask about, ebay sellers? I will buy one from a company so it will at least seem legit. Will a 1j pass nj emission laws if anybody knows? or even any state laws? i just wanna know if i have a shot at making this my daily driver. Also, can i use the r154 tranny from my 7m? if i get the 1j clutch parts? And finally (for now) do you think its worth it to get the 1jz, premade extended harness ($850), and the bic motor mounts, rather than overhauling my ill-oil-pressured 7m? Any information as quick as possibly would be a BIG help. Thanks.
