WOW - I need to get back into the B15 scene and see what every1 is playing with now. Every1 said I was "crazy" back then and that I should stick w/ the turbo kits. Haha
99% of the people in the b15 sceene are still retarded, but there is a laptop based ECU reflash/tuning now, lots of improved parts, stuff I've worked on, etc.
If you want to do it chances are it's out there, or can be found.
