What is considered the most powerful engine/pipe combo in .21 off-road engines? I need a pullstart capable engine with a standard glow plug. If you have a combination you like let me know also, I some suggestions.
dude u are asking a question then changing it.first of all u wanted to know what the most powerful engine is that is a hard question because there is so many fast reliable engines out it is not funny v-spec,p5,rb ws72,73,rb c5 ,rb s5,ops speedster,top 421b and the sirio kanai 2 ,3 just to name a few.but i garrantee u without a shadow of a doubt that NONE OF THESE ENGINES ARE A PULL START.and no matter how much power you have if you cannot get it to the grond it does not matter.also having a standard head limits your choices quite a bit.
have fun with youre searh but try not to limit yourself to a pullstart and a standard head if you are looking for the most powerful engine.
