in mo we have a machine that plugs into the data link connector and reads engine rpm, battery voltage, and scans for codes in the computer. even having the bulb burned out for the cel fails emissions here. the only way around it is to plug it into another car. may be my only option if it comes to it. oh by the way when you guys use the b15 clutch on a 96 n/a de do you use a dealer friction disc?, i know its supposed to be double sprung but when i look at exedy or other oem replacements they all have the same part number for basically all the sr20s. i didnt feel like starting another post and i just searched thru like 100 pages
