this might seem stupid by no one just finds an rb30det, they are all built to your specs, there was never a factory optioned rb30det. tommy keira (spelling) did offer a rb30det using the head off an 2L NICS rb20det, they are one of the rarest cars in the r31 skyline range..
if you want to know the process to build one of these engines then you'll find all the info on the planet you will need at
