Got a 88 RRC with no engine more than likely gonna put a old rover v8 in it but I have fantasized about putting in a m70 v12 or a AJ v8 from a xj or xjr but I don’t have the funds for that type of build 😂
It seems pretty similar in terms of setup, but with an updated variable geometry turbo and as you say an alloy block, but I don't know a great deal about the B57 in truth
Well I used the m57 engine but I had to get a adapter plate to fit m57n for the zf8hp70 gearbox because its the only gearbox I can find that you can buy a transmission controller/ turbo lamik It's still a ongoing project tbh
