its not the sump style that will determine it. Most of the front sumps were in Chasers?
The ecu connectors will be different so you need the ecu from the same car.
Body plugs will be a lot different to wire up as well if it is going into a MKIII Supra but it has been done. Its documented here on the forums. The sensors and all that are the same. If it is going in any other car...then it should not make any difference.
