Castle motor for 1/8th truggy

[CerberusVI]

So right now i have a Neu-Castle 1512 1.5y 1800kv motor that i bought on impulse that i thought i would be able to use in my Mugen MBX5t, but come to find out it's going to be a little small and possibly get a little hot.

So ultimately i would like to get my hands on a 1518 or 1520 but i havent been able to come up with any really for sale. My question is how well is the 1515 2200kv motor going to preform on 5 or 6sin a 9.5lb truggy? I know a lot of people are using these now and could use a little direction.

I've may have already found a local buyer for my 1518 because im just trying to off it now and fund something else.
