It's a 3s-fe running standard apart from K&N air filter. It really has been a great engine and has only just done over a 100,000 mile. I dont know if it had anything to do with it but i hit a large puddle i couldnt avoid on a dual carrageway just minutes before then after stopping i reved the engine and BANG! I've sourced a engine with only 40 odd thousand mile which im debating wether to get or not, funds really are tight at this time of year. Does anyone know exactly what i would need to do inorder to change it to a 3s-ge, would the ecu fit straight on the wiring loom for instance? I really am GUTTED
