I've installed an .18 tz eb modded in a jato 3.3 there are some minor mods we made we put the engine mount spacers on the top of the engine side so the motor sits lower. We also cut the shaft so we could use a bolt in the end with a washer. Lets just say were very happy with the setup no motor problems at all!!!! now on its 3rd gallon with the same cb bearings that same nut and washer holding the clutch bell bearings on. Havent stripped any spur gears and by putting the engine lower it will improve the handling.
