you right about that bro, i've never thought about the j spec 300z, and your right as long as your car is registered as a TT, and as long as the cat and MAF work right, you should be able to pass somg just fine, that sounds like a great plan, you know of another such loopholes?
SPEAKING OF J SPEC- i just got my new j spec GA16 tranny (new not a used one) unorthodx flywheel, and a stage four 4 puck racing clutch. all i have to say is OMG, the gear ratios in the tranny have a lower final gear so the gears are shorter and its quicker. it makes SUCH a night and day difference. anyways, tonite a went to the street races in santa rosa, NUTTIE is all i have to say, i beat a tricked out gen 3 acura integra gsr by 2 1/2 car lengths!!
.... i must add that i have 2 1/4" mandrel bend cat back, apexi dunk exhaust, a high flow cat, hot shot headers, weapons r dargon intake with a custom large dyer hose and a sheet mettal air concotion (in other words a home made ram air kit) that cuts off the heat from the rest of the engine, so that it only breaths only the air coming outa the dyer hose. i'll admit, its a bit funny lookin, but works better for me, then a CAI, i live where it rains and snows a lot and the filter gets destoryed in the winter, and if your not careful you blow your engine!... ANY WAYS my car is way faster now and now i can burn the tires in 1st and 2nd and get a nice loud chrip in 3rd, and 4th a small chrip. its sooooo fun, i baby it when i'm not racing tho, which is not offent, i really dont fell like buying another clutch nay time soon!
