Hi Guys! At the moment I have an rb25 head and a rb25 block without internals. My plan was to build it up with rb26 crank and forged rods and forged pistons. But I look more and more at rb30e bottoms. Is it a better choice to build an rb30 with forged internals and the rb25det head then to build a rb25det with 26 internals? Is it possible with 8000-8500rpm with a rb30 with forged internals? I will build for about 450Rwkw or 600rwhp.
