Hey, I reckon you are better off with a JP FX T03 the three port version as it is ifmar and roar legal if you plan to race competativly. They are a very nice little motor though. The TZ is also an excellent and very reliable motor but i dont think it quite has the horsepower of the JP. its pretty much up to you, ive seen both these motors go and they are excellent so your pick!! Hope this helps!
p.s go for the JP! LOL
