Nissan Sunny Tuning

"Listen up 'Sunny'!"

Handling modifications are usually your first port of call for the Sunny. We suggest that you fit uprated suspension and lower the car by 30-35mm. Larger drops require arch work - especially on models already equipped with sports suspension.

Turning our attention to the Sunnys engine we need to get a bit more power out of the top end.

Smaller engines do not provide much of a return in terms of power so start with a bigger engine. Engine swaps are a good option if you have a small engine size to begin with.

Nissan Sunny Tuning modifications.

This will help to ensure you retain some economy low down. Fast road cams offer one of the biggest performance gains as far as a bolt on part goes. You will need to ensure that the engine is not starved of fuel so will need to uprate the fuelling. Improve your cars response to the throttle with a Fuel pressure boost valve. To get sufficient fuel you may need to uprate the injectors on your engine. A fuel pump will only deliver a finite amount of fuel, so you may need to uprate this.

Nissan Sunny Intake and Exhaust.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Maximum power gains come from a full induction kit. On small engines you will actually lose low down power so we suggest you use a panel air fitler instead. Sports exhausts will certainly help air flow through the engine but do not go too large. Stick to 1.5 to 2.5 inches for best results.

In nearly all cases of Sunny tuning your clutch will start to slip and this needs to be uprated - read our article on clutches for more information. Nissan Sunny Wheel modifications.

Because alloy wheels are lighter they improve performance and they help to cool the brake disks. The downside to large alloy wheels on your Sunny is that you alter your effective final drive ratio and this will have a detrimental effect on performance. Aim to keep the overall rolling diameter of the wheel the same as supplied from the factory. In all cases we do not recommend going above 15 inches.
