A "real" b-series would take more time & money in parts & labor that an H22 swap.. If you got the B20 for 600, you then need to buy tranny, alt, starter, ecu, harness, custom axles, convert for cable shifter to shift linkages.. Not mention its not going to clear the hood since b-series motors sit up right & the B20/1A, H22/3, F20/2/3, motor sit at an angle & all use cable shifters
