I have a 89 Crx dx with a d15b7 and Pm5 ecu, from what I've read so far is that the s300 will not work with my ecu. What do I need to be able to make this work, a different ecu and adapter for the harness? I've looked around the site and can't seem to find what I'm looking for.
I would like to turbo ...
