RE: 4A-GE: Bigport with smallport fuel injection
smallport and bigport have different injector spacing so the fuelrail isn't interchangeable. ECU, fuelrail and head should be from the same model ideally. you could switch the head onto the bigport block and retain ecu etc. there's many other mix and match options but it really depends what your goals are and how much work you want to put in to it.
