os .18tz vs. orion wasp .21

[TMAXX BASHER]

I want the engine that will be better for pulling wheelies, cheaper to run, and easier to tune? Which one would be better, the os .18tz or the orion wasp .21?
thanks

The os .18tz uses a turbo plug which is a more expensive plug than normal but will add more performance and output. Not familiar with the wasp .21. But have you considered the dynamite .19T? I have it on my tmaxx and its already twisted two drive shaft ends and is plenty fast enough and very torque happy. I'm not a big wheelie fan so i run my slipper a bit looser and have the wheelie bar mounted but for fun i did tighten up my slipper once and had no problem pulling wheelies across the grass and on the driveway. It was really kinda uncontrollable till i loosened up on the slipper again. Its only $109.99 delivered off ebay.

The OS .21TM is a drop in replacement engine for your maxx.
