The K04 in the mk1 LCR is the K04-023 (I think it's K04-022 for early 210 models but it's the 023 for the 225 and later 210s). I read somewhere that the mk2 Leon Cupra and mk2 S3 have the K04-064 version.
But as Bill says they're similar in name only really. The Mk2 ones are built into the exhaust manifold, the mk1 turbos bolt on to the mani.
Just some more trivia for you.
That's a bit unfortunate for mk2 owners who have a turbo or mani problem, that's probably gonna cost a couple of grand from the dealers.
Tom, by the way, Congrats on making the 300bhp mark. You reckon the 3" tip made a significant difference yeah? Maybe I can take a look at your setup one day or at a meet?
