Lantra Tuning

"The Lantra Mantra is 'Go Faster'"

Many Lantra owners uprate the handling of their cars as a priority, this will certainly increase your enjoyment of the car. Drop the car optimally somewhere in the region of 35mm and fit stiffer dampers, bigger drops will need other modifications in most instances.

We were asked questions for more information on tuning and building a modified Lantra and particularly which turbo upgrades work best, so we've put together this feature which covers our go to parts for this engine and what we feel are the optimum value parts you can do.

The Lantra is a good tuning project to try. With the right mods your Lantra can be transformed into a fun car. Don't waste money, do your homework and follow our unbiased guides to each performance upgrade so you don't waste your money.

Tuning tips and articles
Turning our attention to the Lantras engine we need to get a bit more power out of the top end.

With our tuning guide your Lantra can be a track day fun car and reliable daily run around.

For NA (naturally aspirated) engines please watch our video which covers the 5 principles of tuning your Lantra. Be sure to keep up with our latest YouTube content and subscribe.

Best mods for your Lantra

  1. Braking Mods - Enhancing your stopping power ought to be high on your agenda.
  2. Lantra Handling Mods (suspension) - Fitting a more sporty Suspension kit dramatically improves Lantra handling Poly Bushes and Coilovers are typically fitted to achieve this
  3. ECU Tunes - A Remapped Lantra ECU provides the biggest gains compared to cost, aftermarket ECU upgrades, and piggyback ECUs are all alternatives.
  4. Upgrades to turbochargers and superchargers - A New Turbo is the most efficient approach to increase air supply, allowing you to burn more fuel and make more power. It is one of the most costly upgrades but provides the best gains.
  5. Fast road Camshafts are one of the most significant mechanical changes, but they must be installed by someone who knows what they are doing and they are not always easy to source but you might find a local firm to regrind a stock camshaft.
  6. Intake Mods and Exhaust Upgrades - NB: on their own these mods won't ADD POWER in most cases, but they can help enhance power after other mods by removing the restriction.
  7. Internal engine mods - crank, pistons, conrods & compression ratio including balancing and blueprinting

Lantra Tuning Stages

Typical stage 1 mods often include: Suspension upgrade (drop ), Alloy wheels, Sports exhaust, Panel air filter, Lighter flywheel, Remap.

Typical stage 2 mods often include: fuel pump upgrades, Fast road cam, high flow fuel injector, Power/Sport clutch, Ported and polished head.

Typical stage 3 mods often include: Adding or upgrading forced induction (turbo/supercharger), Engine balancing, Competition cam, Internal engine upgrades (pistons/head/valves), Sports gearbox.

Lantra Handling/Suspension upgrades

Handling modifications are top of many to do lists for the Lantra.We suggest that you fit performance suspension and lower the car by 27 - 37 Larger drops require arch work - especially on models already equipped with uprated suspension.

One of the most popular reasons for tweaking your Lantra is to improve its handling. However, we see the same mistakes repeated repeated again and over.

Upgrading your Bushes

What factors should you consider when setting up and selecting your suspension if your Lantra is also used as a daily driver?

The suspension components of the Lantra may be mounted and moved around the car's chassis through bushes, which are rotating rubber mounts. The rubber ones will degrade with time.

New OEM rubber bushings may have a major impact on the performance of your vehicle compared to your old worn out ones.

Because polyurethane bushes are stiffer, the ride may be less forgiving, but the bushes will last longer and maintain the car's handling over a longer time.

They may also hasten the depreciation of other suspension components due to the increased vibration and play.

With a new set of poly bushes, the excessive play associated with rubber bushes may be eliminated.

Many people believe that a 60mm lower Lantra from a franchised component shop would be ideal. However, this is not the case a subltle approach is needed on the Lantra to suspension mods.

Vendors may claim that their Lantra suspension kits are compatible with any or all model year Lantras but different engines and weights will require alternative settings and drops.

For a vast variety of vehicles, a 'compromized' approach is obviously incorrect.

How low should you go on the Lantra?

TorqueCars research and testing indicate that the maximum suspension drop for most road vehicles is 27 - 37 millimetres, whereas the maximum suspension drop for cars that are factory fitted with lowered springs is 20 millimetres.

Tolerances may be greatly lowered by altering the diameter of the wheels. Lowering a vehicle, even with 17-inch wheels and stock suspension, may create several issues.

Because the Lantra is lower, less air travels under it, which may aid in stability; nonetheless, the main goal should always be to enhance handling. It is critical to use the proper shocks when employing lower springs buying matched components as a kit.

If you set the toe out to 0.8 to 1.3 degrees on the front, and add a small amount of negative camber then cornering will dramatically improve.

Lantra Brake Upgrades

Fitting meatier brake discs and better high performance brake pads can make for greatly enhanced stopping.

Bear in mind that motorsport pads can be noisier and will need a lot of heat before they bite.

On a road car the brakes are only used rarely and will not stop you as well so source pads which have a low working temperature.

The best power gains come from larger engine sizes. The more you start with the bigger the return on investment so engine swaps are good value mods for small engined cars. By raising peak power you maintain economy in the low end and ensure reliability (unless you drive it like you stole it!).

A fast road cam will be one of the best power mod you can do mechanically to your engine. You will need to ensure that the engine is not starved of fuel so will need to uprate the fuelling.

You can get a more snappy acceleration by fitting 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.

Lantra Turbo upgrades

NA (naturally aspirated) engines need quite a lot of work when you add a turbo, so we have a separate guide to help you take into account the pros and cons of going this route on your Lantra.

The more air you can get into an engine, the more fuel it can burn and uprating the induction with a turbocharger upgrade makes massive power gains.

If your car has forced induction tuning mods are giving better power gains and you will discover turbo engines are made with harder and stronger components.

However engines have limits so discover these limitations and fit better quality crank and pistons to utilize the power.

We see many tuners spending a lot of money on turbocharger upgrades on the Lantra only to have the engine go up in smoke on it's first outing after it's been completed.

Big turbos will usually experience low end lag, and low capacity turbos spool up more quickly but do not have the peak end bhp gains.

We are pleased that the market of turbo chargers is always increasing and we commonly find variable vane turbo chargers, allowing the vane profile is altered according to speed to lower lag and increase top end performance.

Twin scroll turbo chargers divert the exhaust flow into two channels and direct these at differently designed vanes in the turbocharger. They also help the scavenging effect of the engine.

You'll commonly see there's a limit in the air flow sensor MAP/MAF/AFM on the Lantra when loads more air is being drawn into the engine.

You'll see that 4 bar air sensors coping with quite large power gains, whereas the OEM air sensor sapped bhp and torque at a much lower level.

Adding a supercharger or additional turbo will make large performance gains, although more complex to install. We have this guide to twinchargers if you want to read more.

Hyundai Lantra Intake and Exhaust.

Now we move on to the intake and exhaust and ensure proper flow through the engine. Induction kits work well on turbo engines and larger engines, for the smaller Lantra engines you should go with a sports panel air filter. Do not go with the biggest exhaust you can find - the best for power gains are usually between 1.5 to 2.5 inches.

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

Superchargers are generally easier to add than turbos. Turbos give boost in exponential proportion to increasing engine speed and this can make mapping difficult. Superchargers however will give a boost which is proporttional to engine speed so is easier to map. Decreasing the engines compression ratio will allow you to add forced induction, water injection may also help prevent detonation.

Hyundai Lantra Wheel modifications.

Alloy wheels will help the brakes cool down and are usually lighter than the steel ones. The downside to large alloy wheels on your Lantra is that you alter your effective final drive ratio and this will have a detrimental effect on performance.

Although some people have gone larger we would stick to a 18 inch rim size as the maximum.
