I'm planning to get a JRSC with a Hondata stage 2b. What else should I get. I'm currently running a b16a/obd2. Do I reallly need the accesorries for the supercharger, such as the intercooler that JR sells? Also, on the Hondata website, it indicates that I need a donor obd1 ecu. Do they sell this, or do I need to source one on my own.
