no the d series tranny will not bolt up to a b series motor... you need stuff for b series motor... youl need new well dont have to be new but different motor mounts a different ECU shift linkage, axles, the intake and exhaust manifold have to be for b series motors... after that tho u can use ur current exhaust hope that helps a bit
btw do the swap lol its better then the d... asuming engine is in good condition
