RE: the OFFICIAL R-40 thread !
Remember what I told you about the evo 3, there is a problem with the placement of the conrod on the cranckshaft making those motors blow easily. You can't buy the tz eb mods piston sleeve seperately because they don't sell it. You have to buy the whole engine. My job sells the regular and the eb mods. If you want a sirio see if you can find an evo 2, which are the motors they display with the kyosho 1/10 because they don't have the same problems that the evo 3 have. I run a evo 2 now, ans it is super fast. Not A whole lot of punch but a bunch of horsepower.
