Rb30 Bottom End

[dinosouar]

hi, my rb25 needs a rebuild and im considering rebuilding a rb30 bottom end and using the head from my rb25 after doing some mods to it. can someone tell me if this harder than what it sounds like. like does this engine fit straight back into my r33 and work with existing engine mounts and manual trans. am i wasting time and money and stick with the original rb25 engine. thanks dean

There's a 180-odd page thread on the RB30 bottom end swap already in the FI section.

its quicker and cheaper and easier to put in another rb25 and sell your old blown engine. unless you want a huge amount of power.
