Hi,
I have a VL Commodore with a naturally aspirated RB30, done near 300,000KM and it's screwed. How tricky is it to go to an RB25DET and what mods will have I have to do to the engine bay? Is it worth doing this or would it be cheaper to rebuild the RB30 to take a 35-40 Garrett turbo which will set me back roughly $12-15K?
Also where do I get a good RB25DET from? I live 3 hours from Brisbane.
Thanks heaps
