STS turbo in a 100 series???

[Nickslexi]

I love my 100 for all the great reasons to own a Toyota LC.... however, there are two things I'd like to work on.... power and gas mileage. My LC is stock with 285s and in mixed use driving, I get maybe 13mpg. I wouldn't mind all thatt much if it was a barn burner.... but it is not

I used to own a 2004 Pontiac GTO and I installed an STS rear mount turbo system... here is a link Squires Turbo Systems - Turbocharged Innovation!

Now, I really don't want to debate the rear mount technology, because I will tell you it works... and works well.

I was thinkng that this turbo might work really well in our 100's. The only drawback would be where the trubo sits for offroading and water crossings etc. But most of us aren't that hard core and the power would be appreciated...

Any thoughts?

Not a scare tactic but:

Just means you'll have to add the cost of some Lextreme Forged H Beam Rods at $650/ea plus installation!

Holy Crap...$650 EACH?!!! Hmmm...guess I'd keep the boost low and take my chances.

More power=more gas.

I know you said you don't want to debate, but why rear mount?

You think the rods are expensive, I found the website with those and they also have a custom stroker crank. Takes the 4.7 out to a 5.6 or something like that.
The crank was only $7,000.
I think I would just buy a new Tundra 5.7 under warranty for that much hassle.

The rear turbo is interesting, but I sink my Cruiser way too much to even think of stuff like that. But for street use, it sure looks like it would keep all the heat out of the engine compartment.

I know you said you don't want to debate, but why rear mount?

Because it keps heat out of the enigne compartment and cools the charge as it heads back towards the front of the engine. At 5 psi, no need for an intercooler.... read the site and it expalins it all....

I'm not asking how it works, im asking why that instead of a traditional mount? Well, you have your reasons...

My response explained exactly WHY instead of a traditional mount... because lower underhood temps are better for the engine, turbo etc. With the turbo out back, you lower the overall temps.. and with the turbo out back, the intake charge is cooled as it travels up towards the intake. THis is better too because a cooler intake charage makes more power. If you can do this without the compelxity of an intercooler, all the better.

Did you read their site? They will tell you why. Most web-experts( you know the them, they are the guys who have no practical experince but spout off like they know everything and their opinion is gospel), will tell you it doesn't work, the turbo lag is horrible etc. I am here to tell you all that is not true. I've installed this kit on a 2004 GTO and it works very, very well, for relatively little cost compared to other systems. I think I was all in with the turbo kit, injectors, programming etc for $4k.

I also don't buy into the weak rod theory... but then again, I don't want to be a web-expert because everything I know about this I have read. I do think though that the 4.7 in the LC is much differnt from other 4.7's in the Toyota lineup. I get the sense that the material of the rod more than makes up for the size. Remember, you can have a big old bulky rod made out of crap material and it will fail too. I am doing more resrach into this. I will admit if I am wrong, but I have trouble believing 5 psi will cause dmage to this jewel of an engine....

I have twin-rear mounted turbos on my car, wait the motor is in the back too!

I have been thinking about this for a few months. The biggest problem right now the intake position. I would still like to take my truck off road and the intake have to be rerouted inside the cabin if you want to prevent any water intake.

If I ever go this route I will get the basic kit or even better with Junkyard turbo. I would not go over 3 psi with this system though. 3 PSI with remote mount would feel the same as 6 PSI with front mounted Turbo. The GT35 they recommend might even be too big for my application. I want the power delivery to mimic Turbo Diesel with torque down low although this might cause problem with the transmission tuning.

The engine in LC use the same connecting rod as Tundra. They are well known to break under high boost. This is proven in middle east and they would not turbo charge V8 LC anymore unless you update the internals. Even TRD supercharger system could blow this engine when the pressure spike above the rated 6 PSI.

Well, I wonder what was undated in the engines that make 270hp+? I still have a hard time believign that 5psi would cause signifcant dmaage to the con rods.

If anyone has as source fro detailed engine if, I'd apprecaite a link. ANd Why are the aftermarket rods so epenseive? $650 per rod X 8 is $5,200.

A set of custom rods from Lunati, Manley etc., isn't more than $1500
