Also, which 1.6 Vitara manual gearbox.
Suzuki used two different models of 1.6 engines in the Vitaras, the SOHC, G-series in the first & second generation models, and the DOHC, M-series in the fourth generation models, first & second gen. is a longitudinal mount, front engine, rear wheel/four wheel drive, fourth gen is a transverse mount, front engine, front wheel/all wheel drive, so VERY different.
