i was wondering if any of you guys fabricated a Turbo system on a tundra v8, since it has a kind of low compression ratio and a lot of under the hood space. I think the only problem would be with the transmission which I think can be solved with a toyota tacoma manual transmission. Imagine that it worked with reniforced rods and low pressure pistons. hitting boost of 1 bar is no problem with all the dynos around there ( I mean USA). 1 bar I guess would get you around 550~600 BHP..easily. Its something I think possible but $$$ would be the issue.
I saw some pics of a twin turbo system on a tundra V8 but was told that it had horrible problems with leaking oil and it wasn't really good on power....just looked good.
And the tranny issue has been talked about a lot here....and a manual tranny won't fit work the 4.7. The problem is the tanny is controled by the same computer and the rest of the engine....so if you try to put in a manual tranny the computer won't know what to do. There is a company that will upgrade the 4.7 tranny's valve body for about 500 bucks so it will shift harder and be stronger for more power, and they also sell a better torque converter. So that would probaby be the best bet if someone was to try a huge power set up with their tundra with the 4.7.

over here (United Arab Emirates, UAE), we have LandCruisers v8 4.7L that can come with manual transmission which is really strong. so I think if we take that trans and fit it on a tundra !? you think it will work? or will we have the same issue of transmisson and ecu recognition?! and about the leaking of the engine it seems that the guys building the twin turbo have missed on the oil catch tank. FI an engine means that this engine is going through extremely high pressure so you would get the oil bursting out of the engine breathers .. so you got to have oil catch tank..

Just my own thought
Hang tight for two years or so...we'll have one under mine running 10.5 lbs of boost. (altitude)

Well i know that I would love a manual.....would be nice if it worked

Would that one not fit? if it fits the cruiser and the lx470, wouldn't that be the same motor and basic engine bay design as our tundras? You would probably have to fab up new intake piping, and get a custom made exaust, neither of which are difficult at all... The exaust manifolds and turbo are the difficult parts.
It could I guess but then you'd have to think about where to run the pipes. I'm not sure if the tranny or transfer case would get in the way of the pipes from one side. Yes it would be nice....just a lot of time to fab up everything and people like to buy kits.

10 to 1 compresion is not low, you need typically 8 to 1 for a turbo application to be able to run big boost, you would probly need a head spacer to lower it if you where going to do a turbo system, otherwise you'd be driving a grenade

Agreed. Idealy you want 8/1 to 9/1 CR.
Wouldn't be able to tell you exactely, but I'd make a guestimate of a max of 8PSI boost at 10/1 on 93 octane...hardly worth the effort. The fun starts at 13+. You'd just want more, it wouldn't be enough for the $$ invested.
Any higher CR, and you'd be seeing parts of the motor that you are not supposed to...
Of course, you could just buy 100+ octane fuel, and that would help the predetonation, but it's like $5/gallon and up here in florida, where you can find it...

So again....good in theory but not too well suited for our motors. They last long but that doesn't make them bomb proof. Compression is huge factor!! A person would have to do some serious work to the motor if they wanted to go crazy with a turbo set up. This is the same reason why people have problems with running 9 psi with the TRD superchargers. Our motors aren't bulit for this kind of power.....nor are the trannies.

In my opinion the only issue with running the set-up that Slee sells would be tranny mods. I took my 05 Tundra into Slee's shop to compare with their turboed cruiser and there would be few things that would have to be routed differently but it would theoretically work. If I could get the same numbers out of my Tundra for the price tag on the turbo system, it would money well spent. I just don't want to be the guiney pig. Brad.
