Hi everyone, here I am coming to collect some information because I don't know in how long I will do it, but here I am going to start my research to buy a spec2 engine for my R33 GTST S2, and my questions are, because I have seen several versions if the compatibility is good ... for this engines (RB25DET from Stagea Spec 1,2,3, RB25DET AWR, and RB25DET Spec1,3) would be compatible with our r33 GTST S2 and manual gearbox, and if so ,what modifications to do if there is .., the only thing I know is that the Spec 1 are compatible with modifying ignition, and for the RB25DET in AWR it is modifying the oil pan, i have also a loom and ECU RB25DET S2 manual gearbox,thanks🙂.
