Back years ago Honda-tuning did an article (can't find the article) involving a B16 with a stock bottom end with the exception of Arias pistons that they literally just had installed without balancing the rotating assembly. The motor was tuned on Motec, and the damned thing made nearly 600 hp. Not sure if this was with C16 or not.

The pistons must have been close to stock B16 weight, and i'm not sure if it was PR3 or P30 pistons that were removed.

Any help would be appreciated.

 

Arias forged pistions will work at near 600hp. You'll need rods too to make it last longer than a day.

The part number will depend on the bore and compression you want. You can get from 8 to 12.5 compression in a 81-86mm bore. They have 23 b16 pistion options...

 

I have that magazine. Found it on the web for you so it can stay in the bathroom. Here you go partner.

I'll never see the 600hp mark. More like just over half of that number so I can drive it everyday. The thing that interests me is the fact that the pistons are of a weight that they are able to be dropped in without balancing. At least I think this was planned. Hell if all we know the damned motor was out of balance bad. I'll simply say that i'm assuming that the balance of the rotating assembly was taken into consideration beforehand.
