Thanks Bret, I was struggling too to find a high flow mani, reading about some of the tubular types cracking I felt more comfort with the cast option, and from an engineering firm that know what they're doing..their mani for the K03 seems proven. One thing I will say is that having a mechanic whom you trust counts for a lot. You have Alex, I have Richard from Enigma Automotive, Channel Isles revo specialist. The first thing he noticed when I showed him the JBS mani was some moulding cast off (not sure that is the right term) on the inside, but said with some light dremmaling he could smooth this out. I wouldn't have noticed this or if I had thought it would make a lot of difference, but he knows clean flow is key.
Logging is an issue, but more for Richard as he doesn't like to log above 3rd gear for safety reasons (speed / breaking in short spurts). We have a RR (not at Enigma sadly), but I've heard they've blown some engines

. I do however come over to the uk a few times a year & over to France. Plan is to track it eventually in France, there's a club over here with some really nice motors; Porsche, Ferrari, lots of Astons all common as muck over here, but in my class some Subaru's, Evo's, 370z etc that go over a few times a year...i would be the only LCR
Anyhoo still so much to do, & like you I don't like to things by half...clutch, diff, oil coolers or wmi, bushes, arbs...it's never ending but I love it..
