just posting for a mate thats halfway through doing a turbo conversion on a berlina and has hit a road block. The turbo engine was taken from a written off vehicle and has some damage to the head. What sort of differences are there between a turbo rb30 head and a NA rb30 head? Both series 1 and 2 differences aswell if there are any. Thanks guys Some original photos have not been recovered yet.

just a cam rest is the same also try the search button as it is working
