I'm going SC with 2.8 pulley (got it from Pulley Boys) with an intercooler. Just need to get it all on the rig. I also have the EMS exhaust which will help it all flow better.

Are you going to run an intercooler? I would be very curious to see your gains. Are you going to dyno it at all?
I'm hoping to dyno once its all done. Smaller pulley, IC, and exhaust. We will see! Some guys have already been down this road and have results. Do a search on intercooler and dyno in the title and it will bring up some good information.
I chose the Cummins 6bt route.

Toyota diesels aren't really a cheap option, and if you add the turbo and intercooler to the 4.5, then the diesels aren't even in the same zip code.
Having built both turbo intercooled petrol, supercharged intercooled petrol, and having had 1hdt tuned, zorst, big intercooler, and 1hdft multi valve with all our good bits too, both auto, and manual, of all, for the smoother, quieter, more powerful 4.5 turbo intercooled petrol, hands down, cheaper to service, less oil, less fuel filter changes, cheaper to buy.
The only thing that would change me would be the exhaust noise of the 4.7 if converted, with intercooled positive displacement supercharger, but still not the power and torque the 1fz will make.
The guys here even organised an economy run many moons ago, to compare the 1hdft/1hdt/1fz and my turbo 1fz, [was late 90's, turbo 80's were as rare as 1hdft's then] same servo to fuel full, same servo at the end to fill, xl spreadsheet, only one 1hdft used .5 litres less fuel than my 80, everyone else used more.

I've been tossing this around. Diesel conversion for me is not an option due to the fact I don't want any more lift than my OME 0". That leaves a V8 repower or forced induction. You may go from 15-19 mpg with the V8, but driving 10,000 miles/year you will only change your fuel consumption by ~140 gallons, so less than $500 per year.
I think there are pros of each, but for all the headaches of the V8 transplant I think forced induction may be the way forward for me. Plus you are still 'pure Cruiser'.
I'm thinking a EMS stage 3 (to leave the door open for more fuel later) although I doubt I would ever go the addional fueling route.
If only my exhausst would hurry up and fall apart I could justify making the purchase!

Well, how do I increase power and efficiency for my 1FZ-FE without swapping my motor to any V8?
I don't want to have to bind my self with higher grade of octane. All forced induction alternatives will bind me to that. Yeah I get more power this way but not practical for my daily driving.

Unless you have the time, $$$, shop and fab skills the SC is hard to beat. It bolts on in a day, is $3200 and the 80 gets plenty of hp for normal driving.

How much more work do you figure a bolt-on EMS turbo kit would be than a supercharger?
Have you seen any TRD kits for sale recently? I think they are sold out.
I'm obviously biased, but am quite happy with the combo of an extra 0.1 liters displacement (yes it makes a difference), TRD SC/2.8" Pulley/Water to Air Intercooler. No dyno runs, but I'd put my educated guess at 90-100 hp over stock, and the torque is even more impressive.
FWIW, the stock 1FZ-FE makes 212hp, the early non-VVTi 2UZ-FE 235hp, and the later VVTi versions 270hp, so not quite +110 over the 1FZ-FE. Definitely a great motor though, and a very good option if determined to do a swap.

I did the SC. It is easy. Hardest part is removing crank pulley bolt and cutting and extending the MAF/VAF wiring harness. Everything else is bolt on. SC takes a day. I did the radiator and a few odds and ends at the same time and was done in a weekend.
Never done a turbo. But, there would be exhaust work, oil line lube, water line cooling, intercooling, etc. Can't imagine you could do it in a day but maybe I'm wrong.
I believe CDan has the SC.

The EMSPowered bolt-on kit would take 1 day for installation. Maybe 2 if you're unfamiliar with your truck. There is no fabrication involved. Every piece of the turbo kit is all designed to literally ''bolt on'', even the downpipe/exhaust.
Cool.
What's the cost ?
I presume it is carb legal.

The only forced induction for the Land Cruiser that is CARB legal is the TRD supercharger. No other forced induction setup for the Land Cruiser is technically CARB legal, none. BUT, it will pass an emissions test, the sniffer test, and keep your ECU working happily. As long as the state inspector doesn't fail you on the "visual' part of the inspectoin. That all depends on who is inspecting it. And if you're in a part of the country where they don't care about whats what under the hood, then you're fine either way.
Costs are on our website here: http://www.emspowered.com/storefront/index.php?main_page=index&cPath=61_119_120_216_217
We'll be working on a more entry level kit soon as well, without intercooler, for the more budget minded owners. Which will be along the same price range as a TRD supercharger.
Actually, the Safari Turbo is carb approved as Executive Order D-490. It uses a Garrett T04E turbocharger. I was actually going to assembly my own system using their design and pass it off as the Safari, but it only exempts 95-97 OBD II 80s so I went with the TRD SC.
The TRD SC is carb approved for all 92-97 trucks using a 4.5L 6-cyl engine.

The 4.2 Atlas is a good one for a 275hp/275 lb-ft swap while losing 300 pounds. Couple that with a smart 4L60E tranny, a decent combo I think. I've driven an 80 with this combo and it's impressive I must say. Definitely not a neck snapping accel but passing people is very easy and painless.
