this 5 port would have been my purchase if they had it back then. the 3 port is a great engine for $150, it has enough bottom for truggy, not crazy bottom just enough. some people think if the tires aren't spinning out at every blip the engine is soft. the top end is good with the 2035. buy one and run it for 5 or more gallons then get another, its not rocket science. the more gallons you get after 5 the better deal it is. if you want to spend $300-$500 at once for an engine go right ahead, these keep up just fine and they don't hit the wallet so hard either, and when they do GO, you just get another.
