were going to run into the issue of OBD2 smog here. OBD1 is fine because its a sniffer, OBD2 plugs into the ECU. thing is, the Japanese never adopted the OBD2 system so theres no way of smogging the cars OUTSIDE OF sniffing them. So its gonna create a whole heap of issues... and believe me, I CANNOT WAIT until I can buy myself a low mileage and well kept S15 Silvia Spec R Aero (Ive been building S13s for over 15 years now and my DorkiDori product line is based completely around the S-Chassis)
