Available in standard form with power of upto 322bhp (depending on the year), so this goes to show the tuning potential of the Grand. From this you can increase the power from anywhere between 354.2bhp to 547.4bhp and this would take a lot more than just bolting on a massive exhaust and adding a go faster stripe.

For serious power hikes like this you would need to look at rebores, porting and polishing and add into the mix a hefty dose of forced induction.

An engine swap with that from the 322bhp Grand Voyager will give a massive power gain and provide a better base to work from. The more powerful Grands respond exceptionally well to tuning mods. The most frequent modification we see on the Grand include sports exhausts, air intakes or induction kits and a fuel pressure boost valve.

The Car Tuning Guide recommend that on the Grands , you get a fast road cam. Internal engine modifications that should be high up on your list would be polishing and porting the head.

The Grands come in various power levels right up to 322bhp as per the Grand Voyager If you apply a few tuning mods to this model of Grand you will see power gains from anywhere between 354.2bhp to 547.4bhp. But this sort of power requires some pretty heavy investment and a hell of a lot of engine work. .

The forced induction Grands are around with some impressive Turbo and supercharger conversions being done. These give impressive power gains over standard but require a lot of effort to get working properly. If you have a turbo or supercharger get the intercooler uprated for even more power. The most powerful Grand has a healthy 322 bhp. In a competition setting you may well, with some forced induction, reboring and other major work see power figures between 418.6 bhp to 611.8bhp with mods we have outlined above.) High on your list of mods for your Grand should be handling improvements. You shouldn’t really lower a car by more than 30-35mm.
