3RZ ECU QUESTIONS

Post by TWITCHIN »

Hey just bought a 3rz conversion with nearly everything except the
ecu, rang wreckers today and they said that there are a few different ones, said they needed a code from the ecu that came with the engine to match em up. But neither me or the guy i bought it off have the original ecu. Does anyone know what the go is, are there different variants in em.
i thought they were all the same :? . obviosly not. the engine is from a 2003 2wd if thats any help. :?

cheers :)

No dude the 3Y one won't work. Same happened to me when I bought mine. The 3RZ fork is longer and needs to be for the clutch to work. Best off buying a new throwout bearing. They will tell you that there are heaps of different models but just tell them it's from the 2003 2wd. Get the model number of the hilux it came from.

It's a Boost box to increase the KPA flow around the mass single plane throttle body it's running. Thats the pipe i was asking you about the other night as it may have some info on it that would help you find the correct ecu, however like most have said any manual ecu should run it.
plenty of parts on the bench

There's one with a plug what has a red/blue wire and a white wire. It doesn't go to anything on mine. I just have it tucked through the firewall out of the way.
