Toyota Supra Tuning guide.

"A Supra Power"

The Toyota Supra must be classed among one of the most reliable sports cars released by a modern car manufacturer. 

It was produced in the 1993 and the last of the models rolled off the production line in 1996. 

 The twin turbo engine produces 327 BHP and pushes the car to 60 miles per hour in just 4.9 seconds.

Originally the Toyota engineers designed the engine to produce a massive 600 brake horsepower.  Executives however bowed to market forces and cut the power back to almost half its originally intended level.  This ensured reliability and better fuel economy.

It also means that the engine is over machined effectively making it bulletproof. TorqueCars expect to see power gains upto 700bhp before having to get the engine machined and toughened up.

Designed for 600bhp Toyota reduced the power due to market forces leaving a tuners dream.

Fuel economy is not the major concern of a Toyota Supra over as the car will typically return around 20 miles to the gallon and use a set of rear tires every few months!

Traction is probably the biggest problem affecting the Toyota Supra.  A softer compound tire will certainly help.  And many owners fit wider rims so there is a greater contact area with the ground. See our wheels and tire articles for more information on this.

The beauty of the Toyota Supra is the simplicity required to exact high power gains.  The combination of a boost controller and remap will raise the power to 400 to 500 BHP.  At these power levels you will benefit from the cold air induction kit and full sports exhaust.

The following modifications are usually performed by our members, decide how far you want to go before you begin.

Getting the right mods for your planned usage of the car is vital. Stage 3 (competition) mods just don't work well on the road.

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.

There is much debate as to whether a large turbo conversion or work on the existing twin turbo set up will produce the best power gains.  Certainly for drag racing where sheer peak power is important a large turbo seems to be the way to go. The lag of a large turbo can actually help to reign in power for the launch and let the car come on boost as it starts moving.

You also have the option of a large twin turbo set up and boost controller to smooth the power delivery and help compensate for lag. Or why not mix and match have a preliminary small turbo then feed in a larger turbo for the best of both worlds.
