    Maybe, take the hatch off and have a temporary dry pipe bent up at the local muffler shop to use for tuning. Once you get it all tuned, swap back to the banks elbow.

    I have the elbows that are shown on the right in this pic. The water is introduced to the exhaust just before the hose connection as shown in the 2nd pic.

    That is a good idea and it might be my best bet. I was hoping to use that FiTech EFI kit though which means I would need the o2 sensor permanently. I really wanted to go that route for piece of mind but I might just have to go with a carb.

    This is what I was thinking of doing and I'll let you guys tell me if it's ridiculous or not lol. What if I had a spacer made to go between the turbo and the Banks elbow? This way I only have to have one item fabricated and can pretty much keep what I have. I know it might not look the best having one side sticking out farther than the other but at the end of the day, no one will see this engine under the cover and I'd rather have the engine tuned right than have it look pretty.

    I appreciate the feedback. Thanks guys.

    This is a jacketed 180 degree elbow with an O2 sensor bung that I made. You could make (or have made) a 90 degree elbow, which would be easier. Inner tube is a mandrel-bent 3" O.D. piece. Outer is 4" O.D. which had to be sectioned, since the bend radii were different. There is a short piece that is uncooled where the O2 bung is welded on, so you couldn't run this under a closed compartment, unless you made a water-cooled shield to clamp over the uncooled segment.

    You can header wrap short sections of unjacketed exhaust.

    To keep water out of the exhaust you will have to jumper the water around connections. Dump the water in the exhaust tip through the transom
