well i was going to get a seperate wideband unit that was not connected to the aem. and the non wideband is $1,700.00 shipped. with wideband is over 2.. yes iam serious.. iam finishing buying the final parts for my suspension this week. i finally got a excallent paying job so iam trying to finish my z in 6 months max. then start on my 2.5-sti conversion. so iam bumping up the priority of this car.. iam convinced the only way to make an ultimate reliable z is a strong bottom end supporting mods and a stand alone computer.(the jim wolf chip can get you but so far..)
