an increase in displacement does not allways acheive more power once again f1 engines big bore short stroke high revving torque they are able to make 900hp without a turbo by shortening the stroke of the 25 decreases the overall stress on all the parts at a given rpm wich is also what the rod ratio is good for hp is torque times rpm /5252 a direct relationship between torque and rpm yea being able to generate a higher revving toque due to the increased ablility to rev eg better rod ratio and shortened stroke is that not a good thing

like what making just a rb30de/det instead of a 24

Have you completed the build yet i hope u went through with it as im wanting to build one myself if you could pm me that would be good also is there a difference between the rb25 crank and rb 20 from what i understand isnt the ability to rev higher with the same power alow for faster 1/4 mile times eg hondas and f1 cars
