    The Corvette guys do this, I was AMAZED at how far away the turbos can be located (behind the Rear Tires!) but it sure looks like a Plumbing Nightmare! And, YEA, deep pockets....

    Re: Remote Turbo question

    The big problem is modifying the fuel injection/delivery system to keep from leaning it out and burning up the motor. Unless you have buckets of loose cash available I'd forget it.

    Re: Remote Turbo question

    If they can make turbo and super charger kits work on the 3.6 camaro then why can't it work on a cadillac?
    Just because its not listed specific for your car doesn't mean it can't work.

    Re: Remote Turbo question

    As posted, given enough time and money, ANYTHING can be made to "work". Some efforts are just more practical than others ..........

    Quick - name a supercharger or turbo kit for a Northstar. (and NOT a CHRfab Northstar. The engine in a stock 2008 STS 4.6.)

    Re: Remote Turbo question

    Why does it have to be a specific kit? Specially with these under car mount turbos. Find some one who can bend and weld pipe and someone who can do a tune. Throw in some bigger injectors and your going racing.

    Find me a specific turbo kit for my lsx powered 67 firebird. They don't exist so I have to build my own.

    LC3 blower mounted to the LH2 with injectors air intake accessories and a retune. Run on lower psi due to thinner cyl walls and less head mating surface. Next riddle!

    Let's see you pass smog tests with that setup. It'd take a miracle to get the CEL to go out so that everything important wouldn't be disabled.

    I think TimmyC said the spool time of twin turbo on the N* would make a lot of turbo lag. I think you would have to run some pair of tiny tiny turbos to reduce this like ones made for an engine that it about 2.0L like a Jetta with it's 1.8L turbo since twin turbos use the exhaust from half the motor to spool you would want to use turbos that are sized accordingly.

    Wont be hard to do with a tuner who knows what he is doing.

    If you are running twins you don't want to go too big anyway. Go too small and you might as well not do it at all. B.B. turbos have come a long way and spool time is not bad anymore. Almost non existent in some cases.

    Sorry but NOS are not turbos . Remote turbos are a pair of turbos that are mounted underneath the car and use the exhaust gas to spin the turbos .

    I gathered that from this thread...Just had never heard the term before, I have seen turbo set ups like this, can't imagine it being anywhere close to affordable without a very fat bank account or loaded parents that hand out money like it's candy...

    I just found a company today that makes a complete remote turbo kit that contains everything you need to add remote turbos to my STS and I'm waiting for them to take their test car to my friends dyno so I can get some real accurate performance numbers .

    Yes but the 3.6 is a V6 and my 4.6 Northstar is a V8 .

    I was just looking for others opinions and wondering if anyone else has ever done this . As for a kit that is made for the car my Lincoln Towncar had a twin turbo system fabricated for it and it works fine but it did cost a pretty penny . I look for kits first to save time and money .
