hi gus i am building an rb30 using r33 rb25de head and a rb30 block and want to know how to set up vct internally if possible. i no you can set it up externally but want to know how to do it internally.there is a forum on here saying how to set it up by drilling into a bung just under the cam but was wondering if any one has done it this way and does it work?also is there any other way to set it up?
cheers chris nz
