Weird problem going on with a B20B swap into my Civic hatch... we've gotta dial up fuel pressure to 80-90 psi to get the thing to stop running INCREDIBLY lean. We're thinking it's either the injectors or wiring (OBD2 clips were spliced into the wiring), has anyone ran into this problem on a swap before and please let us know how to best diagnose the root cause. Thanks in advance peeps.

ef ect

I am in the same boat, kinda. I had to set my fule pressure up to 55 @ idel to get the computer to stop giving a lean code but the plugs were a little white. Tis fixed my problem but the only thin is that now i get like 16-20 mpg WTF???!!!. I was aleast hoping for 30mpg. The only thin i can sugest is to get on the throttle a little and then shut the car off and go look for leaks around injectures or banjo fittings

P.S> b20b swap in to 97 hatch

if you are using the b20 injectors, take them out and use the cx injectors. the b20's flow the same

if they flow the same, why would you change them out? BTW, im using my b20 injectors and no fuel pressure regulator and I seem to be getting excellent gas mileage compared to the d16.
