Huh, I'll be damned. Too bad someone's been playing "I've got a secret!"
and didn't share the results with the rest of us.
I don't plan to have the EJ25 too much longer, so it's not worth it to change over at this point, but it certainly would've been interesting to play with the TWE header back when I had the ported heads and reground cams on the engine.
