Im building a head for my h22 all skunk2 valve train with pro 1 cams.... and while i was looking around i found these... has anyone heard of these if so are these drop in pistons or do i need machine work. My porblem is i don't have the money right now to sleeve the block. thanks

 

Im running this brand pistons in one of my gsr's, w/ the NPR rings, so far about 2k miles. So far so good, its my weekend/drag car so its driven hard and sees lots of abuse.

 

hard to believe those are nippons for only 200$... IIRC Nippons were higher end and usually pretty expensive but i could be wrong on that so wait for others to speak up.

 

Notice though, they aren't Nippon, they are Nippon Racing, those are 2 different brands. I have also seen Nippon Racing piston rings which are garbage compared to the NPR rings.
