My friend's friend car was timed at the CSCS Time Attack event.
It's pretty much a built up Integra Type R with a K24 engine with built internals. I was told he was running Pirelli slicks.
My friend in his S2K did a 1:22 and his brother did 1:24 in a 350z about 2 years ago.
Go check the CSC Racing time attack results.
