Yeah a 2zz MRS would be about even with an S2K, doesn't have double wishbone but is a couple hundred kilos lighter.
Against a lotus it would be far behind.
Again though when you consider price.....an s2000 or 2zz MRS would cost around about $15k just for the car if you want it road registered. $15000 will get you a heavily worked over turbo/2GR with suspension/tyres which will be faster than either of those cars stock.
