I'm looking to get some information about the pros or cons or if this can even be done?
I have a b16 block and possibly will need to change my piston rings. If I'm in there and I can find a set of pistons that are better then stock (Same trim as stock though) can I safely use them on stock rods? I'm not trying to get all into machine work on the block, just thinking of some possible options.

 

What type of pistons? Like RS Machine?

Are you trying to bump the compression?

 

Whatever can work on stock rods safely so that I can drive the car...

I mean if there are pistons that I dont need to machine the block in order to fit that are better then the stock ones in the block, the logically if im going to change the rings, i might as well do that then... I was just wondering if there are any that can be done...

I might just try and find a new block though... I'm weighting the cost options...
