As there was no need for distributor (MPI used ignition module mounted to cylinder head), valvetrain cover (in previous engines unchanged since 1964) could be made narrower, moving accessory belt closer to engine, so engine could be fitted to VW Lupo. Injection system was upgraded, now using two lambda probes and drive-by-wire throttle valve.
