Good day one and all. hav a single cam rb20 in my c33 at present, wana upgrade to the Rb25 non turbo. I would like to know if there is any one out there who did this swap and what kinda performance did you get, thanks in advance
RB25 non turbo does run real good compared to the rb20. Its dual cam so doesn't drink as much fuel as the single cam. I had a RB25DE installed in my C32 laurel and a Rb20E in my A31 . But since you got the c33 i recommend you go full RB25DET since you can get r32 skyline suspension to line up bolt for bolt also along with s13 suspension.
