I have searched this forum quite extensively but haven't found the exact answer to my question. I have a 1994 Integra GSR without the motor. I have a LS motor that I can put in the car. I am wondering how the LS motor will run on the Vtec ecu. From what I have gathered I will have a CEL on constantly, above the Vtec engagement point the engine will run rich, and the rev limit will be set higher. I am planning on running racing this car so the running rich sounds like it would be the biggest problem. Is there anything I am missing?
