    I have k100, a 2.5" catback, a tegiwa m and the RRC manifold from the fd2 in my ep3. I got 231bhp and 156lbft when remapped. Revs to around 8900rpm. It's fun.

    So I certainly wouldn't buy one as a performance upgrade, as a replacement then yes it would be a good option.


    I had almost the same set up and it made 243bhp from memory, drove really well. Then I fitted a Rotrex and had 360bhp for a year. Now I've gone back to NA again, this time with a skunk 2 ultra inlet manifold, so I'll know what that does on top of an rbc in a few weeks!

    Yeah, not looking to buy the TB for performance gains but maybe as a replacement so the car flows better when putting the cams on

    I had Skunk2s, albeit Stage 1s, in my first FN2, and needed a new tensioner and chain when it got back from a week at Spa and Nurburgring. I'd already been warned about the springs and had done them.

    I then went to the TDi-North cams helping test their development ones that ended up morphing into their drop in cams.

    The newer Skunk2 DICs that have been released since have made really disappointing numbers.
    Tdi-North's cams make more power, don't need any of the aforementioned upgrades and are a true DIC. They may be more expensive but they'll give you better results.

    However as mentioned, all need custom remapping and you need to have done all of the usual breathing mods to see the benefit of any cam upgrades.

    Depending on mileage, particularly if your engine is a bit leggy, then with a cam upgrade it may be shrewd to replace the chain and tensioner and inspect the guides while you are at it.
    What valve train did you run with these cams loxy?

    I stuck with OEM collets, but went for Skunk2 Pro Series dual valve springs with Skunk2 retainers. Wherever that car is, it will still have them in...
