What is a strong 0.15 size aftermarket engine to race with?

I'm gonna race my single speed jato in an off raod class and the stock engine is shot. I need to run a .15 in the class i wanna race in so what aftermarket engine would be better than the trx but still be a .15?

How about Fantom FR15? The rotary carb, threaded shaft, non-pullstart version is $99 at Stormer's right now. Might be too much power for a 2WD though...
