  • intercooler piping for s13 180sx sr20

    hi guys,

    i have been hunting around for a reasonable solution but am yet to find it.

    basically i have a 180sx (240sx) with an s13 SR20DET in it.

    i have replaced the stock turbo with a T2871r and am looking to fit some descent pipes to the turbo, from the turbo to the cooler, cooler to the throttle body.

    i have a FMIC fitted already (came with the car)

    so can anyone point me in the direction of a descent setup with minimal joins?

    Ebay sells pre-bent piping kits for your motor configuration (13/13). I always ran those on my bottom mount 2871 setups with minimal work required. For ~$150-160 a set (couplers/pre-bent piping/cheap t-bolts) it really can't be beat when you compare it to custom fab work, etc. If you don't wanna run their hardware then I usually grabbed new couplers and t-bolts.

      You can move the radiator back a couple of inches and put the I/C there. It makes the piping much easier, shorter and cleaner.

        best solution is custom fabrication with mandrel bends, with the only couplers being to the turbo, intercooler and throttle body.

        My builder (Formula D pro) fabricates custom intercooler piping that doesn't have any joint couplers because each coupler introduces a break in the piping, which results in drag and can reduce responsiveness. The shortest distance, least number of bends, and don't make it too big so as to keep velocity up...

          I run this on my s13.

            That IC looks great. I wish I had known about that earlier, my chinaspeed IC was nearly the same price and is already losing most of it's "Powder coated" paint.
            Simplify, then add lightness.

              Be aware that you must cut the bumper core and remove the headlight motors with that kit, both of which are illegal in SM if you autox.

                No cutting the bumper core necessary on the PBM kit. That's why I went to it. On an S14 you don't have to do any headlight BS. You can replace flip up lights with fixed non flip up lights in SM now.

                  If you want to keep the pop up lights and you have electric fans, you could use the above PBM kit and move the radiator back like Loger did with his custom set up. You would have to shorten the pipes and have a bead rolled but not a terrible amount of work.

                    The description on their site says "*not compatible with AC condenser, pop up headlight motors, rad support gets cut - see install shots!". I read "rad support" and thought "bumper support", my bad. The OP does have an S13.

                      No worries. I have this kit for the S14 so I figured I'd chime in. My old front mount actually notched the bumper support so I went this route to be 100% legal and on my car, it is. I was also looking for better response and it does deliver.
