I thought I may as well chime in here.

The comment re the flywheel was poorly written. Apparently some of the locally made flywheels have machined a toothed edge directly into the flywheel for the starter, which doesn't work well compared to using the Toyota ring gear from the auto gearbox version?

I have a Nissan Ringgear on my 1UZ flywheel, from a Navara I believe.
Works fine.
I'm not sure why they used that and not the standard flexplate one, but they did.

Mmmm, heaps of money you say??? Although "heaps" is a relative term, at present this goes in the DON'T KNOW WHAT I DON'T KNOW category. My initial gut feel is $10-12K, which should drop to around $7-9K for subsequent conversions once the R&D work is out of the way. I would welcome views from those who know better.

Like others have stated, budget double that.
I've spent $10k ON TOP of the purchase of the motor on my conversion.

The W58 seems the popular choice.

W58 will die a horrible death behind a 3UZ and IS430 IMO, but feel free to correct me.

Either take the financial plunge with the V160, or put up with a little lack of shift quality with the R154.

Interestingly, my Aristo V300 has a 4 speed auto, compared to the 5 speed auto in the GS300. I suspect that stump pulling torque prefers fewer, stronger gears. The early Porsche turbos only had a 4 speed gearbox for similar reasons.

The LS430 has a 6 speed auto, maybe look into finding that.

I agree the exhaust will be critical. I would prefer to use the standard manifolds if they fit. My personal experience with extractors/modified exhaust etc over the years says the engineers at Toyota really do know what they are doing. However the exhaust will have to provide a purposeful note to deliver the necessary ethereal quality. What's the go from the cat back?

Unlike most Toyota engines, the UZ series manifolds are usually designed around the car.
Due to the extremely wide motor, very restrictive headers had to be employed.
However, the car still sounds very mean with a restrictive exhaust, it just has problems breathing up the very top end.
