Any opinions on which is better?Going in the usual low budget A6 engine build for boost.I realize these are not forged.Also scat or eagle?Scats i seen as low as 259-269 and eagle seems to be a little more.Thanks im a noob but have been reading/following this forum for year and a half as it was my bible for my first hmt setup.

 

They look identical............the Vitara pistons that people run are aftermarket not oem.

 

The only thing with Nippon Pistons is you get a greater ragne of compression choices because the have 2-3 different piston domes available.

 

u cant use the nippon with eagle rods

 

I wasnt aware of that, good to know.What is the problem with using them together.Thanks for the responces i think im gonna go nippon and scat combo as it cheapest anyways.

 

Huh...I wonder if it has someting to do w/the material used in Eagle rods? I have been looking around and I haven't found any reason not to use nippons w/eagle rods.

 

its the wrist pins

 

They are both cast pistons and not worth a damn... If your gonna spend the money on H beam rods, you might as well suck it up and replace the pistons with some Forged units. Because it doesnt take much for a cast piston to break ring lands

 

So are the wrist pins too small/big?

 

with eagles the wrist pins float and the nippon arent designed that way.
the vitaras on the other hand have the circlips
