I put a ZC in my crx, and it runs great. There is just one problem- If I peg the gas, there is about 1sec hesitation or bogging. Timming is right, cold air intake, and a 89 integra computer. Could this be the computer? Could this be the stock CRX dx exhaust, choking the engine? I fooled with the throttle linkage(which is new CRX Si) and that is definitely not the problem. Any help please, this is a rally car, and I would like to have it sorted before The Black River Stages. Thanks Sean Burke

 

TAKE OUT THE CAT RUN A TESTE PIPE OR STRAIGHTH PIPE SOUNDS LIKE YOUR MOTOR ISNT BREATHING RITE...

 

having the exact same problem on my 91crx engine swap d15jdm,took off the pipe at the headers and changed the fuel filter? no luck still hesitating and bogging?

 

get yourself a pm7 ecu.

 

could it be the hf transmission from the original 91crx the gears seem to be crazy long and no real torque at the wheels?

 

no no nothing with trans if anything it would be the clutch but i doubt it it has to be a sensor on your throttle body check the map sensor

 

check your tps sensor. make sure it is wired up correctly,and testing within specs.

 

i put a dohc zc motor in my 93 honda civic sedan runs great, but it wont rev past 3.5 on the tack any information why that is would be helpful,

 

you should ask that question in the 92-2000 civic forum since this forum only relates to 88-91 civic/crx.
