944 Tuning


A Porsche for the Masses.

We have a few Porsche owners among our members and quite rightly so, the 944 offers good amounts of fun in a great price.

All 944s are good, practical cars. 2.5s are the common ones and are easiest for home mechanics. These come with 160bhp as standard but not much tuning potential. If they get it wrong, the 2.7 engine was better but has some specific parts which are expensive.

The more modern 3.0ltr S2 is certainly a good all rounder and entry into Porsche ownership. 211bhp standard so plenty for most people. If you wish tuning potential though then your turbo model is the ideal solution. Originally 220bhp first of all, then in 1988 they did the 250bhp S model which became a standard model in 1989.

Tuning articles and tips

A highly regarded ‘sweet spot’ for this engine is around 330bhp. Achieved fairly reasonably (should spend around £2.5k) and is reliable. After this you begin changing turbo’s and Maf kits etc and also you jump to 400bhp for another £3k ! There are 600bhp cars on the market! !

Some of our members have used Porsche engines in other projects including a Morris Minor and a number of Classic VW Beetles so there are plenty of mods that you can do to a Porsche engine. Boosting the handling must be your first priority in your 944 tuning project. Drop the car by as much as 35mm and fit stiffer dampers, bigger drops will need other modifications in most instances.

Turning our attention to the 944s engine we need to get a bit more power out of the top end.

Following our techniques for tuning your 944 you are going to end up with a practical scorching hatch that will embarrass bigger cars.

When looking at a condition, history and car is more important than mileage (they are all at the very least 18-27 years old these cars! ) Sills are notorious for rust, blocked drainage tubes are also rust traps. Belts, rollers, tensioners etc ought to be done every four years along with water pump every other belt change.

Porsche 944 Tuning modifications.

One of the best mechanical mods you could do is to fit a speedy road cam and get your head ported and polished. When pushing within the power you will have to pay attention to the fueling. More power needs more fuel. Enhance your cars response to the throttle with a Fuel pressure boost valve. Uprating the injectors is another beneficial modification and will deliver sufficient fuel. A fuel pump will only deliver a finite amount of fuel, so you may want to uprate this.

Porsche 944 Intake and Exhaust.

Now we move on to the exhaust and intake and ensure proper flow with the engine. Induction kits work nicely on turbo engines and larger engines, for the smaller 944 engines you should go with a sports panel air filter. Do not go with the largest exhaust you can get – the ideal for power gains tend to be between 2 to 2.5 inches but this largely depends upon the engine you have with your 944.

An effective fast road power clutch will help to keep that power going where it should. If power has been increased by 30% or more, never skimp or expect a standard clutch to cope. Remaps offer significant power gains on all turbo charged 944’s. On NASP engines the benefits are doubtful, and can help unleash the potential in case you have done a great deal of mods. Adding forced induction will see big power gains but normally, this is too expensive to get cost effective.

Superchargers are generally easier to add than turbos. It is harder to map a turbo because the boost comes on exponentially with engine speed. Superchargers however will offer a boost which can be proportional to engine speed so is simpler to map. To cope with forced induction you will usually need to reduce the compression ratio of the engine.

Porsche 944 Wheel modifications.

The benefits of alloy wheels feature a lower unsprung weight and a lot more efficient brake cooling. The downside to large alloy wheels on your 944 is that you alter your effective final drive ratio and this will possess a detrimental impact on performance. They will also weigh more and this unsprung weight is not good for handling. We know some of our members go larger than this with no problems., although for this reason we would advise sticking to a maximum wheel size of 18 inches
