I've just got myself a set of tomei pistons 87mm... i thought of doing the conversion myself too but i am not sure where can i get a RB30 block from and how much would it cost. please help me. Can i do the conversion with a standard turbo? What are the things i have to replace? conrods? crankshafts? i have apexi power fc and avcr in my car already. Is the RB25DEt head a direct bolt onto the RB30 block?? please help.... thanks alot everyone..
