I am looking to swap a 2.4 ecotec motor into my buggy. I am looking for any information from people that could help me in this process. Right now my concerns are the the wiring harness and to either go with a new complete harness or converting the stock harness. Another concern is how big of a radiator will I need to cool the motor. I am still trying to figure out where and how to mount the radiator. Can the radiator be mounted horizontal with a fan? Any and all help and leads on any parts is greatly appreciated.
