Seat Ibiza Tuning

"The best performance mods and upgrades for your Ibiza."

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.

The Ibiza is small and light and handles well and came with a wide choice of engines. We shall look at the best mods for the Ibiza outlining the pros and cons of each one.

Performance tuning is generally quite high up on the Ibiza owners priority list. The sporty Ibiza models have all sold quite well.

All models would benefit from handling upgrades. So specify a decent set of coilovers and drop it around 40mm. Putting on Polyeurothane bushings will tighten up any old soggy suspension components and sharpen the handling up.

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 16valve 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.

Other performance tuning mods for the Ibiza.

Many owners are fitting 18inch wheels to their Ibiza but this does affect the handling and performance, we've found the 17 inch wheels to be a good balance between performance and style.

The following mods are usually carried out by our members, decide how far you want to go before you begin.

Stage 1 mods: Exhaust, Panel air filter, Remap, lighter flywheel

Stage 2 mods: Fast road cam, ported and polished head, fuel injector & fuel pump upgrades, 

Stage 3 mods: Engine balancing, forced induction (turbo/supercharger), Internal engine upgrades (pistons/head/valves), competition cam.

Fast road cams can make more top end power but aggressive profiles can lead to lumpy idle and make it really hard to drive the car in everyday conditions.

Fuelling upgrades are important when pushing power gains of around 40% or more. It also pays to get the mapping spot on when you start doing any mods to your car, especially if it is turbo charged.

Brake mods make a lot of sense. You will usually find that Porsche or high performance Audi brakes fit nicely onto the Ibiza hubs, you just need to check for clearance. Bigger discs and pads will give much more stopping power and last longer during hard driving conditions such as on a track.
