You seem to be the guru when it comes to the Lexus v8 conversion. I am aware of the issues people have had with the starter between the vee friend of mine has the v8 in a Jeep competition vehicle here and he has had those issues as well as computer problems with an aftermarket Ecu. He is still happy with it. as I said I am a mechanic by trade so if I do have issues I am capable of fixing them
So all recommendations aside, forget the td42 I want a v8. What is the best way to go about the conversion. How did you make your patrol work. Did you stick with the manual box and is there an off the shelf adapter and flywheel and clutch that will work to mate to the td42 gearbox.
Firstly, I am no guru. I have 10 thumbs. They work well on spreadsheets, but are generally useless inside the engine bay.
Definitely stick with the original Nissan gearbox if you can. No other box is stronger.
I have had no issues with mine, but have heard if plenty of issues people had that transplanted the Lexus box.
You then use the 4.5 / 4.8 Patrol clutch.
There is no off-the-shelf adaptor plate that I know of. But I will PM you the details of a guy that does a lot a machining for others guys doing conversions, and who have done quite a few Lexus conversions in bakkies and 4x4s. He may also help you with other technical questions you may have.
When my conversion was done (2011), the popular route was the Spitronix management system.
That was in the earlier generation 1UZ engines. I have no issues with mine. In almost 6 years now, I had to re set it on the Dyno once (in 2016).
Others that I have heard of had plenty of issues having to reset it frequently. The latest software that I have for the system is apparently more robust.
If you are going to use the 4.3 litre 3UZ engine, (more likely as these are more common now), then I would recommend that you use the original Toyota management system. It is plug and play. People have less issues with it. Also more powerful. 460NM and 200kw.
The only downside is that you cannot fit a turbo to the Toyota management system as you cannot change the settings / mixture on the Toyota system.
