I think the consensus is that for street driving, the IC really isn't necessary for the 210 on E85. E85 is so knock resistant that the IC doesn't provide much of a safety factor, as the real limiting factor is fuel and air volume, not knock.
This is interesting -- I'm running non-IC 210 w/ 72.5mm pulley on 93. Everything works great, but was considering flex fuel for the spring to run e85 (as I just discovered a hidden station near my house!). It seems like injectors and fuel pump are highly recommended, so i'd probably go that route.

I primarily don't want to replace clutch -- I'm able to put the car back to stock with only 10-12 hours effort with the current mods that I have on. As soon as I replace clutch... No going back quickly.
