I'm eventually getting cams and i have been told it is best to convert to OBD I. What all do i have to get to convert my 00 Si from OBD II to OBD I besides a harness and ECU?

 

that's it.

 

Yea it is good to convert but my friend runs his CRVTEC EK with an ITR ECU. We've used a converter with a P28 program that feels good. But the ITR ECU seem so to make better power. His motor is just a B20 bored .50mm over, JE pistons, Portflow head, and CTR intake cam, RC 310's, Skunk manifold, and ITR ECU with VAFC. Full interior daily driven he ran 12.62@107

 

**** I kinda got out of my main point. You can convert to OBD1 but like i was sayin he made better power with the OBD2 ECU. What other mod's are you plannin on for ur B16??? If it's basically stock i would just put an CTR intake cam in it and some sprockets. That cam is making good power even in a high compression CRVTEC.
