is it possible to get a JDM header for a canadian 240SX ?
there is a rumour that the JDM is larger diameter and provides more flow.
can’t go aftermarket; must be OEM equipment to race in the ‘stock’ class.
I doubt there is a JDM header for the 240 as I don’t believe the KA was ever introduced in Japan. I used a Pace Setter header before going turbo and enjoyed the combination of the inject CAI, Apex-i N1 Dual and Pace Setter header. There is also a significant weight reduction with removing the stock cast iron header. One thing I did as well was relocate the oxygen sensor to where it can read all the exhaust not just one cylinders.
