RussJZ especially - thanks heaps for your great posts! The chances are I may use the twin turbo for a little while, but this car will be quite heavily modified and raced over time and I'd expect a large single turbo to go on. My other main questions are other drivetrain components. Tailshaft can be made up so no big probs there, but I am really concerned about the diff. What diff could I fit/modify to suit the factory IRS or would I need to go to a live axle conversion and ford 9 inch diff (not ideal)? I am looking eventually to have anywhere up to 500-600 rwkw (on race fuel) by the time I am done with the car.

As far as the ECU is ceoncerned, Vicroads don't have any particular issue with them, it is more the EPA, as new fuel and ignition maps can alter the emissions of the vehicle. As I will be ensuring that I purchase a pre-pollution vehicle (Pre-1976), then I would find it hard for EPA or Vicroads to argue that the ECU doesn't comply with standards. I am unsure of the engine mount and engineers, however I honestly don't feel that would be a major issue. I will be consulting with an engineer before the work has commenced, however I assume the engineer will need to actually see the motor and the engine bay before a comment can be made. By the point, it's amost too late to go back, which is why I am trying my best to research what I can before I buy the car. Thanks for the high quality of feedback. It is much appreciated

Thanks for the link. Here is an excerpt from somebody who has done the conversion: 'Balance is 53% front, 47% rear.Engine mounts moved to off the rails behind the strut towers. disappeared the original mounts from the crossmember which made it easier to set up a 2 turns lock to lock power rack' Seems reasonably well balanced with the major job being an engine mount fabrication which is pretty reasonable. he also mentioned wiring was pretty hard, but I don't envisage that problem, as I'll be using a standalone ECU solution.

Hello all, I'm the current owner of a '72 Mazda rx3 with an engineered 13b turbo and an '06 Golf GTI, and I am seriously thinking about starting a new project - a 2JZ into a 260z. Apart from the obvious modifications such as ECU, fuel pumps, surge tanks, brake and diff upgrade), fuel regulators and other ancillaries, I am wondering how a 2JZ physically fits into the engine bay of a 260z. I have read threads on this from US sites but I am a little reluctant to rely on this, as the steering box and certain parts will be the other way around. I guess the main things I need answered are as follows: 1) Does the motor physically fit? 2) Are there any major modifications that would be required to engine mounts that would make the conversion difficult? 3) Do any oil sump modifications need to be made? 4) Does a standard 2JZ gearbox fit in a standard 260z trans-tunnel? I am aware this is a big dollar conversion, but I want to make sure that the basics of the conversion are doable and engineerable (In other words, I don't want to have to design a new chassis or cut into the firewall to make the motor fit) If anybody has done this conversion, any info would be greatly appreciated.
