you get 14 mpg , nicee
Over 274k miles, I have averaged 14.6 mpg in my 98. That's a mix of city, highway, and off road. Not too bad.

I do have day job! The workshop indicated that the pluming should be completed this week, I'll see if I can get an update next week.

We hope to start it next week, youtube to Follow and to also do the dyno test next week.
LOL! I can't believe you're actually going through with this. I'm really excited to hear how it turns out though!! 
Because, in the end, a V12 is just going to be four more cylinders with no tangible advantage.
With that said, it's an awesome project. Go for it.
Have you ever driven a V12 anything?
I predict that the smoothness and power curve on this V12 100-series are going to be very nice indeed, provided they get everything set-up properly.
Sure you could get more torque out of a Detroit 8-71. You could get more horsepower out of a supercharged Chevy 350.
The advantages here are that the 12 cylinder Toyota is going to be smooth and refined; torquey and perfect for towing; it should also be great for accellerating a 6000 lb cruiser up to 100+ mph with a minimum of fuss. Especially with the 6-speed automatic transmission-
The land cruiser is a luxury vehicle. The V12 (with a 6-speed automatic!!!) has the potential to be a very sensible and appropriate upgrade.
It is just in a different style from the guys who add ladders and loud exhaust to go rock crawling. not better, not worse, just different (and pretty freakin' cool-
) Now I just hope they get it to work.

Couldn't have said it better myself!

Serious intercooler being test-fitted.
Plumbing is a nightmare but we are winning!
Thx for the positive comments guys

Why yes, I have driven a V12. Several in fact. Ferrari, Jaguar, Mercedes, BMW, Lamborghini to name a few. Yes, I've driven each of these. I've also driven rotary engines, diesel engines, turbine engines, steam engines, boxers, flats, V's and W's. Once I even had the opportunity to spool up a twin engine Ford Fiesta. No doubt a V12 is smooth. But the Toyota 4.7L 2UZ-FE V8, originally engineered to anchor the Lexus division, is arguably one of the smoothest running engines of any configuration ever created. Torque and HP can be achieved in myriad ways far exceeding simply the number of cylinders. The fact that this bloke is putting a twin turbo V12 in a 100 Series is outstanding. When completed, it's going to be epic. My original point was simply that the V8 is as capable of producing comparable torque and HP to the V12. DionBooyens had a V12 handy, and seems to have the know-how to make it work, so I'm a fan. I can't wait to see the video of this beast in action.

LC100 brakes are made for 16". Don't know about 500 HP tho; total weight, speed, and tire diameter would matter. Front calipers have 4 pistons, I'll find the bore diameter somewhere...
Nice, keep the updates coming!

LOL, maybe just some reasoning behind me slapping the turbos on. My house is at an altitude of about 5800ft and not all the horses come out to play in a na engine. Boost will be limited to .4 and I'll have the ability to drop it down to 0 boost. This might be the least used function in the LC! The gearbox that we are using is the same as the one in my 200 Cruiser and I am of the opinion that the weakest link will be the diffs and I'll have to look for after market units.
I'm keeping the permanent 4x4 system
To help to correct the geometry of the suspension after a 3" lift a full Snake racing setup was fitted together with 400 kg springs at the rear and 200 kg in front. With the V12 being lighter than the 4.5 I might have to change the front ones to 150 or 100kg units.
The conversion is taking a lot longer than anticipated due to the complexity of the plumbing, we are trying to get equal length tubes from the turbos to the intercooler and also to get the balance right so that we limit the volume between the turbos and the intake. This should help to reduce turbo lag. The dump valve will unfortunately be an external one and that plus the 2x 3" pipes at the back will give away the fact that the car is not std.
I can't wait to turn the key. The dyno will be done at altitude and will not show the full potential, it will however be on youtube.
Cheers

I was referring to how everyone comes out to be an expert and all these technical numbers about weight and all kinds of irrelevant things about tires come flying out and here you are swapping in a V12. It's amazing.
This is starting to sound insane!
I'm super excited to see how it turns out Also, what state are you in? This is something that seems like it'd be sooooo much cooler in person!
