Seat Ibiza Tuning (1996-2008 model range)

"Thank you for reading my Ibiza Tuning guide."

The Ibiza is a popular model and has enjoyed a long production run. Current models bear little resemblance to the original '84 models, particularly since Seat joined the VAG group in 1993.

We have written a new guide to the post 2008 models here.

The Ibiza is a good project car to play with. Take your time and research Ibiza tuning to spare yourself making the usual tuning slip ups we hear about.

Tuning 1996-1999 models the 6K floor plan

This platform was shared with the Polo and had a wide range of engines including a couple fitted to the Golf.

There was a 999 and 1043cc model, niether of which respond very well to tuning mods. The 1.3 and 1.4 engines were quite solid but only the 16 valve 1.4 AFH engine produced enough power to start to enjoy the car. On lower power models and the 8 valve engines we suggest you focus on handling mods and weight reduction rather than spending lots of money on performance mods that in reality will not give much of a noticeable power gain.

The GTI models were fitted with 2.0 engines and the 16 valve versions were much better than the 8 valve equivalents. the ABF engine from 1996 was the best petrol engine in the line up and would make a good donor for an engine swap on the smaller models.

The ABF engine is also a good tuning base to work on giving bigger power gains per upgrade than any other engine in this models lineup.

The AFH, ADL ADL engines are good candidates for tuning and we would suggest internal mods to maximise your power gains. Fast road cams, porting, polishing and a big valve conversion should all give a noticeable power hike. Many owners add induction kits and sports exhausts and whilst these give a sporty sound, the power gains are minimal, especially at the lower end.

Dropping in the 1.8T engine from recent cars would really transform the car especially as these turbo engines can be tuned to around 300bhp fairly simply.

The 1.8 TDI engines were quite lively for a diesel and started to show the potential for performance diesels but these early engines could not be remapped, so you are left with turbo upgrades and other mechanical boost increasers. Our pick of the diesel engines would be the AFN engine producing 110PS.

In 1999 to 2002 the UK's Mk3 model (or 6K2) revision was introduced.

The Cupra was powered by the stunning 1.8T turbo engine and was available in 3 forms the AQX, AYP and a specially tuned R version of the AYP.  A remap on these engines can take the power to around 200 bhp and with a KO4 turbo upgrade and a few other mods like sports cat, exhaust headers and intake mods along with a 5 angle valve job you can see power figures approaching 300bhp. Any more than this and you need to strengthen the bottom end of the engine.

The early AGU engines from VW/Audi had forged pistons and was stronger so a swap to this engine is recommended if you want a simple route to a stronger engine.

The 1.8T engines also had a dual mass flywheel which smoothed things out but were prone to failure so many owners dumped this when they replaced the clutch and opted for a lighter flywheel making the engine a lot more free revving.

The 16 valve 1.4 engines  produced similar power to the 1.6 and was lighter and higher revving, and as such was often favoured but the 1.6 offers more low down torque.

Even if you did every bolt on mod in the book on a 1.0 engine you are unlikely to see more than another 10bhp so once again we have to put our sensible heads on and say you should focus on handling modifications.

The later 1.9 TDI PD engines could now be remapped and offer an immense increase in power and economy when you do so. (Many owners seeing a 30% power hike from a simple remap and 10% better fuel economy!) But sadly few of these engines found their way into pre 2002 cars.

The 6L revision was introduced in 2002

This benefited from a major restyle  and grew in size and character with more aggressive edgy styling. The sporty models to look out for were the FR and Cupra where Seat specially tuned the engines giving them more power than in any other VAG group line up.

These models all handled very well and really showed up the offerings from other VAG group marquees that were based on this revision. A minor facelift was rolled out in 2006 but little had changed on these  newer models.

Smaller engines included the 1.2 and 1.4 with most now available with Double Overhead Cams. These engines were quite zippy in the main revving typically to around 5000 rpm. An induction kit and sports exhaust on these engines will give a slight top end gain, provide a dramatic engine note but do little for overall performance.

The 1.8T BJX and BBU engines dominated in the power line up leaving the larger 2.0 engine scrabbling to find a credible place. Seat focused on improving the engines breathing and managed to squeeze a few more bhp out of these engines. They offer a good mix of power and economy and respond very well to tuning mods.

A remap on these engines can take the power to around 200 bhp and with a KO4 turbo upgrade and a few other mods like sports cat, exhaust headers, fast road cams and intake mods along with a 5 angle valve job you can see power figures approaching 300bhp. Any more than this and you need to strengthen the bottom end of the engine. The early AGU engines from VW/Audi had forged pistons and was stronger so a swap to this engine is recommended if you want a simple route to a stronger engine.

The 1.8T engines also had a dual mass flywheel which smoothed things out but were prone to failure so many owners dumped this when they replaced the clutch and opted for a lighter flywheel making the engine a lot more free revving.

The 1.9 TDI PD (Pumpe Duse) engines could now be remapped and offer an immense increase in power and economy when you do so. (Many owners seeing a 30% power hike from a simple remap and 10% better fuel economy!) Many have exclaimed that these engines had been detuned from the factory to avoid competing with the petrol engines.

We have detailed tuning guides for the following VAG group engines some of which make great engine swap candidates in the Ibiza. (More will be added soon.)

Handling/Suspension upgrades

Improving the handling for car owners first priority in your Ibiza tuning project.

Good suspension tweaks that usually improve handling for the Ibiza include a couple of degrees negative camber and 1-1.5 degrees of toe in or out on the front wheels. Toe in for stability, or Toe out to improve cornering. It would also pay to improve the brakes, by adding larger discs and or higher friction pads..

We would go to a maximum drop of 22mm - 36 mm on most models. You risk compromising your handling if you go lower than this.

Top end bhp should be your overall aim with a nice fat wide peak torque band.

Following our guidance for modding your Ibiza you will create a practical but scorching car that will show up bigger cars.

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.

Power mods.

This list of the stages and sports kits are usually installed by our members, decide how far you wish to go in your tuning project before you begin.

Getting the best performance parts for your planned usage of the car is essential. Stage 3 motor sport parts just don't work well on the road hard to control in slow traffic.

Typical stage 1 mods often include: Lighter flywheel, Suspension upgrade (drop 30-40mm), Panel air filter, Sports exhaust, Alloy wheels, Remap.

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

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

Peak power is all well and good but for a drivable and fun car you need a wide power band and perhaps extending the rev range.

In this article we shall give a little insight into the world to the best performance parts for your car, but we'd encourage you to spend some time on the site looking into the details of each type of performance upgrade.One of the most cost effective mechanical motorsport upgrades you can do to your NASP engine is to fit a fast road camshaft .

The exhaust & intake flow play a large part in your cars power band, but be careful here, getting this wrong can upset the idle and make the car hard to drive in traffic. You'd need to follow a cam upgrade with other mods and finish with a remap to fully realise your gains.

You will need to ensure that the engine is not starved of fuel so will need to ramp up the fuelling.

Frequently power losses, flat spots and erratic idling after motorsport kits are done can usually be traced to timing or fuelling issues.Upgrading the injectors is another beneficial modification and will deliver sufficient fuel.

If you are increasing your fuelling with bigger injectors you will also need to get a bigger fuel pump to supply it.

Intake and Exhaust Tuning.

The next area for modification is the intake and exhaust. Please note that WE DO NOT RECOMMEND INDUCTION KITS, unless you have tuned your car with over 30 percent more power and are finding that the standard air intake has become the bottleneck.

Maximum power gains come from a full induction kit with a cold air feed on heavily tuned engines, this can be sited within an air box but a panel filter should suffice for most applications. TorqueCars suggest you use a panel air filter as these are easy to clean and maintain and generally perform better than paper ones.

Do not go with the biggest exhaust you can get this will slow up the exhaust flow rate - the best for power gains are usually between 1.5 to 2.5 inches. It is the shape and material more than the bore size.

Head work including a gas flow and 3 or 5 angle valve job will really help to release the potential of the engine. A good fast road sports clutch will help to keep that power going where it should. Never skimp or assume your standard clutch to cope. The best mods in our opinion for your Ibiza are Remapping or piggy back ecu, fast road cam and air intake and exhaust

Remaps offer significant power gains on all turbo charged cars. On NASP engines the benefits are doubtful.

However a flashed ecu on a NASP engine will help unleash the potential if you have done a lot of mods. Adding forced induction will see significant power gains but this is usually too expensive to be cost effective. Superchargers are usually easier to add than a turbo. Turbos give boost in exponential proportion to increasing engine speed and this can make mapping difficult.

The nice correlating boost and rpm characteristics of the supercharger make them simpler to map. Adding forced induction will nearly always require a lower compression ratio or water injection.

Alloy wheel upgrades.

Alloy wheels can help the brake cooling and are usually less heavy than the steel ones. Pay attention to your choice of tyres (tires) for your car, a good soft compound tire can really enhance your cars handling. It is worth noting that although they can look cool on the Ibiza large alloy wheels will actually decrease your performance. The larger you go the lower your acceleration will be - this to the change in your effective final drive ratio.

Due to this fact we would advise sticking to a maximum wheel size of 16 inches, although we know some of our members have fitted larger wheels with no problems.
