Tuning the Nissan Silvia S13

"Tuning guide to the most effective Nissan Silvia S13 modifications."

We saw the first S13 Silvias hitting the streets in 1989 winning car of the year in Japan, it quickly became very popular, and did much to establish the reputation of Nissan for making sports cars.

In other regions the S13 was badged as the 180SX 200SX and 240SX just to cause confusion! The pop up headlights are peculiar to this model but we have seen an S13 front end on the S14 and S15.

We review and look at Silvia S13 tuning and provide tips on the optimum modifications. Nissan Silvia S13 make for  really good project cars and with the right modified tuning mods you can certainly enhance your driving enjoyment.

The Silvia S13 is a awesome tuning project to carry out. Plan ahead and research Silvia S13 tuning to spare yourself making the usual expensive mistakes we frequently .

Handling/Suspension upgrades

Improving the handling for car enthusiasts first priority in your Silvia S13 tuning project.

The standard brakes prove to be pretty capable but with a set of good fast road pads you dramatically reduce your stopping distance and increase car safety.

Upgrading to larger vented disks and a 6 pot caliper will really enable you to stop almost dead from any speed in next to no time.

Suspension mods are many and varied. The 180sx is popular for drifting although as a result of this a lot of 180's have parts and even body panels from the S14 and S15 fitted to them.

Good suspension tweaks that dramatically improve handling for the Silvia S13 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..

Drop the car by as much as 30mm - 37 mm. and fit motorsport grade stiffer dampers, bigger drops will need other modifications in most instances.

Turning our attention to the Silvia S13's engine we need to get a bit more power out of the top end.

Sadly with smaller engine sizes you are wasting your time spending money on modifications, so if this applies to you get yourself an engine swap then apply the following mods.

Power mods.

The following performance modifications are usually installed by our members, decide how far you want to push your car before you begin. The 180SX is a brilliant fun sports coupe from Nissan and also makes a practical daily run around.

Engine choices ranged from 1.8 to 2.0

• 1.8 L CA18DE I4
• 1.8 L CA18DET turbo I4
• 2.0 L SR20DE I4
• 2.0 L SR20DET turbo I4

Getting the right sports mods for your planned usage of the car is vital. Stage 3 motor sport mods just don't work well on the road hard to control in slow traffic.

Modifying to Stage 1:

 Suspension upgrade (drop 30mm - 37 mm.), Alloy wheels, Remap, Lighter flywheel, Sports exhaust, Panel air filter.

Modifying to Stage 2:

 Ported and polished head, fuel pump upgrades, Power/Sport clutch, Fast road cam, high flow fuel injector.

Modifying to Stage 3:

 Adding or upgrading forced induction (turbo/supercharger), Competition cam, Sports gearbox, Engine balancing, Internal engine upgrades (pistons/head/valves).

You should keep as much low end torque as possible and aim to get a wide power band across the rev range rather than a narrow top end power hike.

The whole point of our pointers is to give a little insight into the world of modding performance parts and point you in the right direction, our forum is where you can ask for more detailed advice and tips on your car tuning project, the best tuning modifications and all aspects of modding cars.

One of the most cost effective mechanical uprated upgrades you can do to your NASP engine is to fit a fast road cam .

The exhaust and intake valve durations play a big role 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 reflashed ECU to fully realise your gains.

Don't forget to pay attention to the fuelling when you are increasing the power - it makes the car more thirsty.

Frequently power losses, flat spots and erratic idling after sports kits are done can usually be traced to timing or fuelling issues. Improved injectors will enable you to supply sufficient fuel to the engine.

Uprate the fuel pump to cope with the extra fuel requirements of your tuned Silvia S13's uprated injectors.

Intake and Exhaust Tuning.

Breathing mods are usually next up. Contrary to popular belief there is usually a small power gain obtained by fitting an induction kit, they only become beneficial and are recommended after you boost the engines power to the point where the standard air intake box cannot cope!

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 performance 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.

Sports exhausts generally help improve air flow through the engine but avoid an exhaust that is too wide or you may end up will reduce the flow rate. Stick to 1.5 to 2.5 inches as a rule of thumb.

Airflow through the head can be dramatically increased with some professional flowed (porting and polishing). These should match and be setup to take into account any other engine mods.

Your clutch can seriously let you down if it starts to complain and the standard clutches are only ever good for power gains of up to 40%. Fit a sports clutch to avoid power losses through the transmission. The best mods in our opinion for your Silvia S13 are remaps, sports camshafts and induction improvements.

The single turbo 1.8 engine still manages to put out 173 which actually compares favourable to modern cars and with its light weight and rear wheel drive makes it into a fun track day car.

A turbo swap or even a hybrid turbo is an option for those wanting to get larger power gains.

The standard block can reportedly handle power gains upto 250bhp with more on offer if you are prepared to do some strengthening mods. Either remap the engine or fit a boost controller to fully realise the power you have on offer.

NASP engines do not achieve big power gains if you remap them, unless you have done extensive modifications. With turbocharged engines this is another story. A remapped turbo will give big power gains and fully release the potential power of the engine.

We've also seen some tuners playing with twincharged applications and making some seriously high power hikes.

Adding forced induction will see massive power gains but this is usually too expensive to be cost effective. Superchargers are usually easier to add than turbos. It is difficult to map fuelling with a turbo as the boost comes on exponentially with engine speed.

The nice steady boost and rpm characteristics of the supercharger make them more straightforward to map. To cope with forced induction you will usually need to decrease the compression ratio of the engine .

Alloy wheel upgrades.

The benefits of alloys include reducing your unsprung weight and more efficient brake cooling. Get a good directional tread pattern tire to improve your handling and help improve traction on your Silvia S13. We'd like to point out although they can look cool on the Silvia S13 big 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.

With this in mind we would advise sticking to a maximum wheel size of 17 inches, although we know some of our members have gone larger than this with no problems.
