With the RB Touring series, on a small track you would be better getting the T10 or T11, or even a TJ## if it's a very small track, but the T10/T11 are essentially the same engines anyway, just a different head. They have the same crank and sleeve which means identical timings, so theoretically they should perform the same as each other, unless the cases are different and the crank timing has been changed, but I think they are the same.
I hope I didn't confuse you with any of this
