Cressida Supra,
Don't buy any ECU!!!!!!
Go and talk to Alan Gibs. He is the Kalmaker guy. They are looking for someone with a 1uzfe to put the Delco on. I do believe they are still looking for someone. I was going to send my ute over but I don't have the time or $$$. As you are in Perth it will be easy for you. His email is tpiconn@mail.space.net.au
He will be able to tell you what the go is.
