    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
