Title: Cat-Back Turbo
Post by: Jeffy on September 17, 2007, 10:41:47 PM
I've seen a company that did this on other applications but this is the first I've seen on a Jeep.  It would be legal even in CA since it's a cat-back system.

I wonder just how many minutes that thing would last on my Jeep.  I would have that thing ripped off and/or submerged in a mud hole/rock before I could bat an eye.  I'll leave turbo kits to hondas. That's me though

Well, you would defiantly want a skid plate over it, that's for sure.  Turbo's don't have to be peaky.  You can tune them so they make even power through the powerband.  I think submerging it would be an issue though.  I'm sure it wouldn't like ingesting mud either.  I'd like to see it mounted up out of the way BUT this does get around any aftermarket modification issues.

As a Cali resident, I can say that there would probably be issues with the smog nazis. Anything from the filter to the cats has to be C.A.R.B. legal.

This setup is a Cat-back so it would be exempt from C.A.R.B. certification.

Doesn't the turbo have to feed into the intake, though? I thought the exhaust spins the turbine, which pumps higher pressure air into the intake.
That's where I would think the problem would be. Just the fact that the intake (tube) would have to be modified...

Of course, I could be mistaken. That happens much too often...  :confused:

You're right, the turbo has to dump back into the intake.  You'd need to get it piped back into the stock box.  You can see the pipe on the right side heading back forward.  I found his cardomain site and more pictures.  The more I see the dumber this setup is.  The guy lives in Idaho, I think so why he went with this setup is beyond me.  His intake would not be legal in CA.  He has the CCV open which wouldn't fly.  The other issue I can see is not only is his turbo mounted very low, so is the air filter.  It's right next to the turbo.

If you're in CA it would probably be better to use a custom downpipe below the manifold to mount the turbo.    This wouldn't be legal BUT you would be able to remove it before any smog tests.    Although, setup properly, the engine would probably run just as clean if not cleaner not to mention get a bit better gas mileage.

I helped put a system like this on my buddy's camaro.  It was made by Squires Turbo Systems(STS).  It actually is a really cool idea and very efficient.  I found it interesting that an intercooler was not needed due to the fact that the compressed air gets cooled in the very long charge pipe.  For a camaro that's not daily driven I think it's a great idea. For a Jeep that likes to go offroad I stick to the fact that this is a horrible idea.  I would however like to see what a turbo does after ingesting mud
