Hi Omnivore, and welcome to the Forum.

All those questions can be easily answered by searching the Forums.

Low 60's, easy on a 250.

High 60's, relatively simple.

70hp 250, achievable, pretty expensive, but very rewarding.

MC18/300 done plenty of times before. Don't expect 70hp though. More like low to mid 60's with a load of torque (for a 2-stroke). The 300 still needs tuning just like a 250 to get good power out of it, so add tuning to the cost of the kit. Bonus is you get a brand new top-end, not just a reconditioned one.

Some MC18's in the Posers Gallery with TYGA bodywork. Take a look.
