C2J Engine the same?

Hello people
Can get my hands on a C2J engine that my plan will be to use the top and bottom end and do a slow full engine rebuild using all new parts.
I no the GT5 turbo uses a C1J so my question is there any difference other than the auxiliaries that I will use from my C1j I have in mine at the mo when its ready to swap it out.
Its a great price with all C2J auxiliaries so will sell what I don't use or should I just keep looking out for a C1J
Thanks :)

can you get the engine number have the Renault manual here for the engines and there a few different types available its 3 numbers or 3 numbers and a letter. also I take it the c1j is a a turbo
