Rb25 build help please

[banshee_rider909]

So this is my very first build ever so I'm pretty knoob when it comes to parts and combos and what not. I have a rb25 s2 swap on my s14 and want to get 650hp out of it. I know I need to build the bottom end bit thats the problem. Idk what pistons (size, bores), rods, bearings etc. I'm pretty good with the head as far as what to get its just the bottom end is super difficult for me. Thanks would sure love the feedback and comments guys.

Its pricey, but for big power, reliability, to me I is the answer. Sizing just depends on how brave you want to be about the cylinder walls. For a good all together bottom end build/stroker kit, price tag is high... 5k+, but something to look into. But here is what I would do if I had the money and the plans to make large numbers(note, enjuku can be high priced, browse around, this is just for reference)

My RB25 is currently putting down 665 hp with stock GTR rods, stock RB25 crank, CP pistons (8.5:1 compression ratio & stock bore), HKS 264 x 8.8mm cams, Ferrea +1mm valves, with a T04Z on E85.

It takes a lot of extra upgrades besides the block itself to get to 650 hp, which is why most stop at around 500-550hp. It gets exponentially more expensive from there.
