Hey my question might seem some what senseless to somebody with alot of experience with honda builds but here it goes. I got a B16a2 head off a 99 SI with an OBD2 wiring harness. Can I use an older b16a1 block with the head? Can I replace the B16a1 OBD1 sensors with newer OBD2 sensors? and are there any other compadiblity issues I might be unaware of?

 

yes, only thing youll have to worry about is the crank flucuation sensor if your using an obd2 ecu.
