theres not much difference between the 18 size and a 15 size of the same engine brand. shaft size would be the same as so the muffler side and location would be the same and maybe the crankcase size would be the same . without seeing the 2 x engines i would say the only difference would be the piston and liner dimentions is what turns the 15 into an 18. yes worth the extra power difference.
