Integrity, have you had runs against s2000s?

I have a friend with a 350Z (Canadian one w/leather and everything except the cloth seats and brembos?) and no one is really sure if he can take on another friend's s2000 w/mugen i/e/h & ecu..etc. I assume driver skill is equal.

So far the 350Z did well on the highway against another pal's MKIV Supra TT with only one turbo working.
