Japanese 7mgte motors? Advice in swap?
 

Hi I was wondering if anyone has done a swap with a japanese motor off of ebay or rising sun engines. I am wanting to swap a jdm motor into an american verison of the car and i was wondering if everything will link together. Can I use my existing wiring harness with the jdm motor with the existing ECU? What problems would I encounter, and will i have to buy anything else other than the motor?
