Water injection will help out immesely. You don't need excellent flow or high power to reap the benefits of WI. If anything, I think you'll see an even greater difference in temp with a bad IC. Yes, WI will also work well in low boost situations. If turbo rotarys came standard with good water injections, they would probably be priced like Supras.
