I'm trying to do a 300 horsepower build on a y8 I found a ZC h-beam rods I just want to know if they will work on my y8 crank and pistons

 

Eagle lists the same part number for all D16's, including the ZC, so I see no reason why they wouldn't work.

 

what pistons are you using? - most aftermarket forged rods are made to use pistons with full floating pins, not pressed fit pins like stock OEM Honda pistons have

most H-beam rods will require notching of the block to clear the rods

 

I will be using vitara 9.0:1 pistons. So I have to notch the block for me to use the h beam rods?
