Well I have embarked on a new project to install a VGT(Variable Geometry Turbo) from Mitsubishi Japan. It is a TFO7. I have purchased a Rev Hard manifold bec ause it uses a T4 mounting flange which matched the TFO7 base.

I will post pics tomorrow, detailing the turbo and the way its exhaust housing works using the VGT technology.

I will be using this setup on a 4G63T.

I will keep you all up to date.:thumb:
 
Nice hope it works out the VGT is awsome on large trucks
 
Does anyone know of any other references to this amazing variable turbo technology?
I don;t want to discourage you but usually, and I stress USUALLY, if it hasn;t been done before/no one really does it there is a reason.

But I'm very curious and would love to see what you come up with.
 
Good luck on the install. It would be great to see some awesome results.

What kind of flow rating is associated with that TF07? What could we compare it to?
 
http://en.wikipedia.org/wiki/Variable_geometry_turbocharger

The 2006 Porsche 911 Turbo has a twin turbocharged 3.6-litre flat six, and the turbos used are BorgWarner's Variable Geometry Turbos (VGTs). This is significant because although VGTs have been used on advanced turbo diesel engines for a few years and on the Shelby CSX-VNT, this is the first time the technology has been implemented on a high production petrol car (only 500 Shelby CSX-VNTs were ever produced). This is because in petrol cars exhaust temperatures are much higher (than in diesel cars), and this normally has adverse effects on the delicate, moveable vanes of the turbo, BorgWarner engineers however have managed to combat this problem with the new 911 Turbo.

If you go on Jeeps web site and look at the new diesel engine they have it gives a basic description of the technology, although i do not know if this is the same style VGT that mitsu used.

As for why no one really does this mod... these turbos (untill recently) have been fairly hard to come by (by that i mean $$$$$ with some more $$$$$$). They are now finally beeing used in production cars and trucks so the technology is getting cheaper. A properly setup VGT system (not nesesarely using a mitsu vgt just in general) could give you the spool up time of a 14b and flow rate at full rpm of a 20g giving you the best of both worlds no compromise:thumb: if you are still interested check out the late 70s early 80s F1 cars thats were the tech started and pick up the book Maximum Boost (I think the authors last name is Bell) it goes in to pretty good detail about them.

This has never been done because it's relatively new technology.

It's because everyone hasto follow the guy running the fastest car. Everyone wants to use the ''best'' brand name parts, And do what every other guy/girl is doing. That is the main reason, Why not many people try different things. They are afraid to, And want to do the same thing every other car owner does. God forbid if you even mention something different, You'll get flamed for 10 years.:barf:
 
Definatly an awesome topic....consider me subscribed as well. Keep us updated, as i have heard of this before, except on diesels....

New, if you consider Chrysler did it almost 20 years ago. It hasn't really been done because there hasn't been any turbo with this technology that is sized properly for our engines.

It's relatively old technology, it's just becoming more popular with the huge increase in support for diesel engines.
 
Well how are you going to control it? Its not a simple task.
 
Correct me if I am wrong. But is this VGT similar to the Holset with the variable vein technology?

Both are used on turbo trucks while primarily larger engines. Like GVR4592 said, they are no properly sized for our engines...

anyone have a compressor map of this VGT turbo?
 
I've installed a VGT turbo on a 2001 Volkswagon Beetle. It was small. I believe the A/R was .42. You do have to remember one thing though. This technology isn't new. It got dismissed because the veins become carboned up and stick. This causes problems with the system. Ask anyone who owns a 6.0 powerstroke how many times they have had their turbo replaced!! You would need a controller to change vein position with boost. The volkswagon turbo had a simple actuator on it, much like a wastegate actuator, to control vein postion. There is an electronically controlled actuator that has a vacuum supply line the actuator supply line and i forgot the other. Duramax Diesel and Powerstroke Diesels use a magnet to move the rack into it's proper position. I hope this is somewhat helpful to all.
 
Amazing idea, Keep us updated!
My dad (who works for Detroit Diesel) said VGT technology is amazing.
 
I don't know about the water injection. I do know that the duramax diesel cycles the veins when the truck is shut off to help keep carbon from building up. Duramaxs' have much less trouble than the Powerstrokes do ;)

Off topic but:

I have an 05 350 with 112k miles on the clock with the original turbo and no issues yet. Now, the rest of the engine is a piece of shit but the turbo is still working fine. I have had 12 injectors fail, a cracked dp, numerous recalls, etc. I am glad I got the 100k mile warranty but it is up and now time to get rid of it. I will keep my 99 with the 7.3 with 198k miles because all I have had done to that is a wp replacement.
 
ouch. ford did however have issues with their turbos, especially on earlier 6.0. Have you ever heard a what sounds kind of like a burping sound after hard accelerations? If so your turbo is bad. This is usually an early sign the veins are sticking. Next it pretty much locks up. I had a customer come in with an 05 and had less than 50k. His complaint was black smoke and no power. Diagnosis: the turbo was carboned up and was pretty much frozen. Cool stuff ;)

i heard the new 6.0's were much better then the early 6.0's but the 6.4 is where its at...

but at the end of the day 7.3 powerstrokes own them all they aint no joke...

The OP hasn't been heard from in a while,
post the pics!

Well someone with the same screen name is selling the same turbo on the GA board if that tells you anything.
