[QUOTE="Trikky2, post: 504836, member: 240"] Yes putting a 2 litre gearbox on your 1600 will significantly lower the engine rpm at any given road speed. Cooling only becomes an issue if the engine is laboured at too low an rpm - but this applies to any engine and gearbox combination. The problem with doing this conversion is that the 1600 does not develop sufficient power for the longer ratios of a 2 litre gearbox. This means that on a flat road with no headwind your bus will have a nice overdrive type top gear. The problem comes when you have headwinds or anything more than a slight incline. You will need to change down to third rather often. A stock 1600 produces around 58 bhp if its in good condition. You need around 75 to 80 to run a 2 litre gearbox comfortably IMO. Wheel and tyre combinations can significantly affect overall gearing, so if using or considering non stock wheels/tyres its worth checking on one of those wheel and tyre calculators online. [/QUOTE]
