my ironman is absolutely awesome, it pulls from idle all the way to screaming like a raped ape.

i have heard the sprkas are quite the pipes but i have heard that the old style DRD are prone to blowing completely apart, not sure about the new style ones

Sparks or JSR/Nmotion

There are a few used nmotions floating around in the for sale section. Seems to be one of the top performers for the YFZ
