  • Turbo kits = A/C delete?

    Was looking into turbo kits for my uncle's 97 Firebird with the 3800, and saw a kit and it said it required removing the A/C system.

    Is this typical? He'd rather not lose the A/C because it is a daily driver and a hardtop car. If turbo kits all require A/C removal he'd rather go the way of the supercharger.

    Just wondering if they ALL require that.

    Not all. My FFF turbo goes under the K member which allows me to retain the AC.

      What's the downside? Clearance? Price?

        Downside would definately be the clearance issues. Personally, I've waited 10 million years for my parts to arrive, which still aren't here, so I couldn't tell you if it is a problem or not. From those with the kits, no one has had any problems with it. Just take the speed bumps slow is what they say.

        I doubt the price would change either way. That is unless you go with custom forward sweeping headers. Then you're talking $$$ unless you do it yourself.

          I won't make this statement about the FFF kits, because I haven't heard any issues with them. But Shane "owned" his downpipe on a speed bump, and I'm not sure about XJ. Both were under-K kits.

          Teufel (or someone?) notched their K-member to permit pipes to go through under, but tucked up.

          My over-K kit goes through the area where the AC compressor was, both for the forward sweep and the downpipe, so nothing is low. Losing the A/C is not a requirement for turbo kits, but I'd venture a guess that for a complete over-k setup, you'll need to lose A/C. Drone51 is trying to build one that's all over-K, keep-A/C, and relocate PS. He might be on to something, particularly if he goes with a tubular K.

          My kit does work on a stock-K setup.

          One thing to keep in mind is that it's an exhaust pipe design issue.

            Its easy to keep everything above the K and keep all accessories, its called a tubular K member. I heard FFF is working on a couple of cars with this setup.

              The tubular k would be your best option. Not to mention the amount of weight you would lose upfront.

              Just have a speed shop do a custom kit. This is would a lot more practical, plus there would be no middle men. The price difference wouldn't be much either. I wish I would have thought of this before I dove into a trap.

                Tubular K allows for you to run 3" pipe under the k member and still retain stock clearance. After installing my k member and mounting up the y pipe, i had 3 inches inbetween the y and k member. Yes, a tubular really does gain that much clearance.

                IN conclusion, going to a tubular k and runing the pipes under the k is the same as having a stock k member with no pipes going under it.......Follow me? =-0

                  I'll be going down to Houston shortly, hopefully, to get this done. Got a new design worked up, might be going to a larger turbo also.........who knows. [img]graemlins/banana.gif[/img]

                    Yes but I was saying that a tubular K might also gain you enough room to run over-K forward and backward. I'm not sure, because I put my tubular K on after my turbo and !AC.

                      LOL, Im sorry but if you ever took your car to have a full custom kit built, be prepared to be raped to the tune of 5-6 GRAND.

                        If you bought all the parts and asked the shop to fab up some pipes, you're telling it's going to cost 5-6k? Didn't Malice get some shop to finish his piping for 2k?

                        Not to mention, I had a shop offer to redo my FFF pipes (Don't ask...) for $100. This was with no mandrel bends though. But checking through websites you can buy bends for $10-50, depending on bend of course. The flanges can also be purchased for less than $50 bucks. It wouldn't be more than a $500-$600 to put out a set of pipes if you knew how to weld. If if you didn't know how to weld it wouldn't be much more.

                            ok so the one important part that hasn't been mentioned here -- is this. Even if you get all the parts yourself and it doesn't end up costing 5-6 GRAND (it will trust me i've looked), if you live in a state that has smog regulations (not safety checks there is a difference) -- your car WILL FAIL SMOG with a custom turbocharger on it.

                            Trust me I know. Any turbo I slap on my car will instantly make it illegal to drive on the street. or in the state of CA for that matter. make sure you do research beforehand.
