namura pistons

Most people say there are crap and most have good reason to have that opinion, many engines have blown becuase of their weak casted metal.

But I've got about 35 hours on mine and it hasn't skipped a beat. Mybe I'm just lucky... But be safe and buy a wiseco just my $ .02
 
Namura pistons are just as good as stock probably better, but Wiseco are the best

I had a Namura in my blaster and I never had a problem


I second this but wanted to add that the Wiseco is much more forgiving when it comes to surviving a lean condition which seems to happen to a lot of Blasters on this forum.
