• Fftec Motorsports N54 twin scroll top mount turbo manifold kit, $4950 - Too pricey?

      The N54 inline-6 turbo upgrade era is really now blossoming from stock housing options to a variety of aftermarket manifold and turbo solutions. Fftech originally worked on a bottom mount turbo manifold but it seems they have abandoned that setup in favor of a top mount turbo manifold now. This 'kit' includes everything you need to install an aftermarket turbo setup at $4950 but does not include an upgraded turbo making for a pricey manifold option.

      Fftec deserves whatever the market is willing to pay and there are not exactly a plethora of top mount off the shelf manifold options in the N54 world at this time. Will it sell? Absolutely.

      Why a top mount? Speculation by BimmerBoost members is that the bottom mount manifold required too much modification to the frame of the vehicle to fit. As a reminder, BimmerBoost vendors do have working bottom mount solutions for those not interested in a top mount for whatever reason (sleeper, heat in the engine bay, etc.).

      Picture and pricing info below.




      Included in this Kit:

      FFTEC Twin Scroll Top Mount Exhaust Manifold
      FFTEC Top Mount Downpipe
      FFTEC Lower Intercooler Pipe
      FFTEC CNC Coolant Pipe
      FFTEC Oil Feed and Drain Lines
      FFTEC Swirl Pot
      FFTEC Boost Control Solenoid
      FFTEC Valve Cover Heat Shield

        just guessing from seeing how the others went?

        that's how I read it too. He is winning races without even being there! That M3 of his must have magic powers. What do you think the guys who actually went with running cars would say when sticky says, "my car smoked yours at ss3!"

        Wait, where does the turbo go.... through the hood? I really don't think more than 5 people will buy this at this price, but who knows.

        I'm going to have them install one of these top mount kits on our 135i.

        On the price the $5k includes the manifold, downpipe, coolant reservoir & piping, heat shields, etc. You could make it yourself for half the price but I doubt it would be half as nice and at the end of the day, if you're going to have a top mount kit, you want it to fit & look nice IMHO. Click here to enlarge They suggested the Precision 5858sp BB for the application so I'll give that a whirl to start. The turbo is $1600 and then the wastegates are $300ish each.

        I can't wait to see it on your 135i putting down some huge numbers!

        On the other hand though, I've turned into quite the turbo fanatic lately and I'm not sure I'd be using that turbo, especially in a TS setup. The benefit of a twin scroll setup is faster spool, thus allowing for a larger turbo and much larger turbine housing. What turbine housing are they recommending? From the kit in the picture it looks like they have a T4 flange on it. That turbo appears to support 620HP. I'm not seeing air flow ratings for it. Also, the only T4 turbine housing I'm seeing for it is an .58 T4. I'm not sure that's even divided. Maybe they have a custom divided turbine housing for it IDK. What exactly is your HP goal T? is this going to be a quick spooling 1/4mi setup? Or a max HP highway 60-130 monster? Did you build the motor or buy a stock shortblock? Personally, I love what full-race does with their twin scrolls and BW or Garrett turbos. It's no secret here that I recommend the Forced Performance turbo chargers to everyone I talk to LOL. Definitely check out the reviews and specs on the FP HTA3582r (700HP) and the GTX3582r (700HP). I'd def look into a 1.06 or .82 divided turbine housing as well.

        I forgot the 135i was AT. is that why you're going with the smaller turbo?

        Yes it's an AT with a redline of around 6700rpm. I'd like it to spool by 3500rpm which may be a pipe dream but the smaller turbo gives it the best shot. It looks like the turbo has 600rw potential which is what I'd like out of this particular setup. And of course being a top mount turbo swaps are not overly difficult. Click here to enlarge

        BTW I spool that FP HTA3582r at 4000RPM on only 2.4L

        Precision 5858 or 5862; It's a shame you couldn't use a TiAL Alpha since their Oil Lubricated/Water Cooled but Forged Performance HTA's aren't a bad alternative since they both start out as a Garrett Turbo

        Every time at the strip I always drive my own car. Every record set in the 1/4 mile was done by me. Why would that change?

        If anyone needs to verify people here have seen me running at the drag rentals. I don't know why it's a question.
