Here is an interesting approach to turbocharging

The environmentally conscientious would appreciate the after-the-cats installation.
Lotta plumbing, but if the long pipe coming back toward the engine compartment had vanes on them, wouldya even NEED an intercooler?

Lag is right. Since we have dual cats we could certainly do twin turbo post-cats. Spooling up is not the issue. The huge volume of air space after the turbo unit increases the amount of time it takes to build pressure.
Would it be too crazy to suggest a long twisting spindle from the exhaust turbine which would return all of the back to the engine bay to turn the intake turbine? You would get mechanical losses but it can address the pressurization issue. A baby torque tube. I think it is crazy, but I am not a mechanical engineer.

.... still crazy..... gear it down a notch to a leisurly 25,000???
How about a hydraulic means of delivering the energy? Steam? Mice on treadmilll...
OK I give up.

I just called them. They are going to email me the measurments for the turbo so i can see where i can put it at and the guy also told me the specs on it. T04E 60-65 a/r and 81-96 exhaust side. Said the .96 exhaust side will hold boost untill 6k+ rpms and on the carmaros they are hitting full boost about 3k rpms. If i have those turbo numbers backwords someone correct me. I would like to buy my own turbo to do this with.
Sweanders i didnt mean using the break while shifting. I mean holding the break down and the gas to spool the turbo from a dead stop.
Yes i know it will be more lag than having it way up close but hell for the price i think its worth it.

One of the main reasons why a turbo turbine blade turns is the exhaust expanding gasses. Heat of the exhaust. How efficient could a turbo be if it's 6 feet from the ehaust manifold. Bet this has loong lag time............

Looking at the website, it looks like the reburn (or whatever superheating that happens in the cat) pops the heat up a notch. Probably nowhere near the temps coming out the manifold, but could this be part of the design. I am not a thermodynamics student.
What would the heat differential be pre and post catalytic converter?

Exhaust temp (under a load) exiting the head is around 1400F. Exiting the cat 700f (true their is a burning process inside the cat. That's why the A.I.R system pumps air to the cat's bed) Exhaust temp at the tail pipe tip 150f.

After spending more time looking at the installation pictures, I was surprised that the common placement was at the tail pipe.
This is kinda interesting stuff. Give it a try Jack and tell us how you do.

Ok i think a Garret TO4B S trim with a T4 turbine and a .96 a/r for 399$ will work.. Any thoughts? Also it looks like the battery box would need to be removed from the rear of the car for there to be plenty of room and put a muffler behind the turbo so it doesnt sound funny. My idea is to basically flip the battery box over in a sense and partially seal it so that the air filter is in there. Move the battery to the spare tire area. Im not too sure on turbo sizing execpt for the number the guy on the phone gave me any input would be very helpfull! http://www.turbocalculator.com/sale-garrett.php that site has turbos for a very resonable cost...

Ok after lots of searching and a phone call to turbonetics i found the stats on the turbo and it will hold boost to like 6500rpms+.... I found this buried in some turbo forum site..
"Turbo is TO4E 60 trim compressor, P trim turbine and runs a .81 A/R housing. This turbo is capable of a lot"
So once i find something like that for around 300-400$ ill get it.

So what is different about the oiling system on that turbo vs others that require gravity to drain the oil back out of the turbo? I think that may be the secret to the turbo those guys are using. This is a very interesting system. I would assume the turbo would work great if you ran it directly behind some JetHot coated headers. Imagine that in a twin-turbo system. You could benifit from the headers and from the boost supplied by the turbos.

Go Jack go!
I think you'd have enough room with the 'pumpkin' removed, not to mention the rear fender for more stuff, if you removed the antenna motor. No need to remove the battery box.
I wonder if you could use a separate oil supply with an electric pump and it's own radiator to supply the turbo...
Actually though, I wish the battery box was bolted in. I've thought randomly about drilling out the spot welds and making it so.
