my 92 civic has a d16a6 motor and someone told me that the car would run better and have better performance if i got a d16z6 intake manifold and throttle body complete for an 92-95 civic ex, or si because those models the throttle body and manifold are bigger than the others.. they said dx model would work to but the ex and si would give it the right performance, and they said i need a p06 ecu for a 92-95 civic 5-speed, and in my car its just a stock 1.5 ecu..all i want is my car to run better and have the right or better performance, and yes i no its not gonna be fast im just looking to get it right or close to right..any help would be great..thank you.
