    I have a 1990 civic hatch dx that had the original d15b2 and the rings whent bad so I threw in a d15b6 from a 1991 crx hf. I am using the intake manny, headers, and ecu from the b2 (original) but I am using the dizzy from the b6. My question is should I run the hf ecu along with the hf dizzy or or should I run the dx dizzy and ecu. It runs good the way it is now but I think its running pretty rich and I also noticed my exhaust is waaaaay quieter with this engine than when I was running the b2. I'm running a kensie full cat back exhaust. Thanks for any advice.

    using the DPFI intake manifold, you need to use the ECU and distributor from the D15B2 engine - the HF ECU and distributor are for MPFI
