most economical 200hp to put on a v20 cc?

If the only reason you are getting repowered is gas, i don't think it is worth it. if you spend $6000 to get a 40% increase in fuel mpg, thats only the difference between 2 mpg & 2.8 mpg. if you want something newer, more reliable, not as corroded, etc. i totally understand. i'm partial to merc optimax, i still like a 2 stroke. i think with real world fuel numbers and prices of engines, it is the best bang for the buck. but whatever you do, we love pictures..
