RB25det neo to r33 RB25det valvetrain swap?

[mr.nismo1]

I don't know if anyone has done a Rb25det NEO valvetrain (cams, lifter...) to a RB25det s1/s2 and if is posible? Because I know the NEO come with solid lifter vs the hydro from the r33s. Let me know if is posible.

nope, better off buying a neo head and dropping it on a r33 block...really thats all that is different between the neo and the r33.
too much is different in the head for it to interchange.

Yeah, the lifters aren't interchangeable from what I've heard. Also, keep in mind the combustion chamber sizes are different, so you can't just slap on a neo head with out custom pistons or something to change the CR.
