    2nd Gen Swap Vs. BD Iron Horn (3rd Gen Manifold)?

    Hey fellas.

    A couple of questions for the public.

    I'm considering upgrading my 6.7L Cummins with either a 2nd Gen swap steed speed manifold or the cost-efficient BD iron horn turbo kit with the 3rd Gen manifold.

    My truck is a 2017 RAM 2500 6.7L, deleted and tuned with DRD via MM3.

    It has a 5" FLO~PRO, Banks Monster RAM air intake manifold, CCV delete, Throttle valve delete, custom aftermarket air intake, 3.5" aftermarket boost/intercooler tubes, lift and tires, etc.

    However, it does not have aftermarket fueling or STOCK head studs and has a stock transmission.

    With this said, I'm stuck between the BD iron horn S364SXE and the S366SXE.

    Can the truck handle the S366SXE with stock fueling and injectors without being sluggish?

    Regarding the 2nd Gen swap, I like the WC Fab second-gen kits but can't find where to buy them, as they appear to be discontinued.

    Can you help me with this on the seller's location?

    Or do you have any other recommendations for good second-gen swap kits?

    Enclosing, which would my current setup be best suited for between my two options above?

    Thanks!

    I would go no bigger than an S364.

    There will be a decent amount of lag with the S366 on stock fuel and no real benefit.

    The only places I know of that are still selling 2nd Gen swap kits are Evil Fab and maybe Slosh fab.

    You can still get 2nd gen swap kits from Smeding Diesel.

    I am running a Smeding S467.7 billet with about 80K miles.

    Runs like a champ.

    I think the S300s are a little small in terms of the 6.7.

    I also prefer the 2nd gen style manifold due to the center dump to the turbo.

    Which turbine/compressor size to choose depends on your truck's use.

    I know this is older.

    I was just wondering if you pulled the trigger yet.

    If so, what did you decide?

    I'm asking because I just installed the BD Iron Horn S364/80 .9, which is about the same as the stock VGT in terms of lag.

    However, from about 1200 RPMs and up, it pulls pretty hard.

    I have only run the 60hp setting.

    MPG has increased by 1.5MPG so far.

    I haven't towed with it yet, but I can't wait to see the EGTs.

    BTW they have dropped by 100-200 already.

    At the same time, I installed the BD Electronic Engine Brake kit.

    My tune was altered to BD's specifications, and it works flawlessly out of the box.

    Everything that came from BD was complete and fast shipping.

    I only needed outside parts to modify my coolant riser to clean up the engine bay and eliminate the coolant leaks.

    I know a person with the Smeding S364 3rd gen who claims the same results.

    As far as parts, I am not sure.

    I liked the quality of the BD Iron Horn kit and the engine brake.

    I did the installation in the driveway.
