2jzge into mx83

Has anyone out there put a non turbo 2j 3 litre into an MX 83. It sounds like it should be a good conversion to replace the 7M.How much rewiring is required?
At 168kw an MX83 should go well and have reasonable economy.
Does anyone also know the availability of the 2JZGE and price?

Rewiring is going to be a big headache if you're planning to use the factory ECU. Definitely not a plug-n-play job. Note also that the JZ engines are not known for their frugal fuel economy... I doubt it would be much different to the 7M.

How would the wiring and economy compare to a 1jzgte or the Lexus V8?

Can't comment on the economy, but I would expect the wiring to be no more complex than the 1JZ-GTE or 1UZ-FE.
Both those engines are more or less plug in (from the point of view of being able to pull the pins out of their plugs and inserting them into the corresponding positions on the vehicle's loom).
The 1UZ had a few more surprises but essentially both those are relatively easy to wire up into an MX83, so I'd expect the 2JZ-GE to be no worse.

Mos,
Luke is here in Dubbo today,he wondered if the wiring for the 2j was like doing his Cressida, I remember it took you all night and the next day to work out the wiring. Would it be that hard because the 2j is from a later car than the 1J?
How difficult was Darren's V8 to do?

I beg to differ. You need to come over and have a look at my Aristo wiring loom... what a shitfight!!

For what it's worth I can photocopy the relevant wiring loom diagrams out of the manual and mail them to you if needed.

Hi Robbo! 
How's it going?
Luke's wiring was more 'difficult' because the plugs on the MX73 are different to the MX83. Both the 1JZ and 1UZ uses the newer style of plugs found on the MX83, which means only moving pins around is much easier; with the MX73 you either make an adaptor or cut one type of plug off.
As that was the first time I worked on a 1JZ all the pins had to be worked out pretty much from scratch, then checked against wiring diagrams - Scrote's conversion was a lot faster - however I'm still awaiting being let loose on a front cut to work out what the hell the traction control computer needs
In Darren's case, the ECU plug coming off the cowl loom did require a number of pins shifted around and new ones added.
Norbie: a shitfight doesn't mean it's any more complex Admittedly I'm yet to work on an ECU with 3 rows of pins
