The Toyota Volta
I have always been a speed junkie no not drugs but cars and if anyone would have told me I would interested in a economy or ecological car like today’s hybrids I would of said that they were a few cards short of a deck. But thanks to Italdesign-Giugiaro I found that I can have my cake and eat it too.
The Toyota Volta is hot, it not only looks space aged sporty but has the muscle to back it up. At 408Hp this 1250Kg puppy can rocket from 0 to 60 in just 4.0 sec. That’s not too shabby when you consider that took the hemi Supper Bee with 425 Hp 6.3 sec to do the same, but it weighed 1863 Kg. and got about 7MPG opposed to the over 30MPG that the Volta gets.
Electronic ignition systems
All gasoline powered engines require a spark to ignite the mixture of gasoline and air. This spark must occur at the right time and in the correct cylinder. This is accomplished by the ignition system.
There are basically three types of ignition system used: the conventional breaker point type ignition systems that were used in vehicle from the early 1900s to the mid 1970s; the electronic ignition systems; and the new distributor-less or wasted spark ignition system that was introduced in the mid 80s and is still used today.

Engine Management Systems
The Engine Management Systems (EMS) is a microprocessor based systems that controls all major components of the modern internal combustion engine used in vehicles manufactured since the early 80’s It was introduces by General Motors in 1979 as the Electronic Control Unit (EMS)
The original units were a hybrid digital/analog design. This used analog technology to measure and process engine parameters, then used a look-up table stored in Read Only Memory (ROM) to provide precompiled output values. Later systems used a microprocessor to compute more dynamic output values.
Nitrous Injection Systems
Nitrous injection was first used during World War II on the P51 mustang fighter it was referred to as war power. Since then it has been used by auto racing enthuses to gain that last minute extra boost of power.
Nitrous (No2) kits are in fact a performance related product. No2 offers users numerous advantages over other forms of power boost products. They are a low cost and easy to install. Even a greenhorn tuner can install these kits.
Turbochargers or Supercharge
Add that extra boost of horsepower to your engine. Both turbochargers and superchargers have their advantages and disadvantages. The following is an effort to explain these technologies so that you can choose which will better meet your needs.
Both the Turbocharger and Supercharger add extra horsepower to your engine through the compression of air in the cylinder. Compressed air is forced into the intake of the engine, causing a more powerful explosion in the cylinder, which translates to more horsepower from your engine.
Install The Cold Air Intakes For Fuel Economy
That’s right the cold air intake is not just to make your car the next 10 second car. They also can improve your fuel economy. With today continuing rise in gasoline prices everyone is looking for ways toget more miles for that gallon of gas. There is no better place to start than to replace your existing stock air intake system with a high quality aftermarket cold air intake. I know you are asking yourself how is that going to improve my fuel economy.
First you need to know a little about the chemical makeup of air and some basic physics. Air is a mixture of 78 percent nitrogen, 21 percent oxygen and 1 percent trace gas. The nitrogen and trace gases are of no use in causing the explosion that make you car engine run.The oxygen combined with the gasoline is what makes the explosion.
The number of air molecules referred to a density is directly affected by the temperature of the air. So when a volume of air is heated it expands therefore causing the air to be less dense. This being said it stands to reason that coldair is denser and contains more oxygen per volume.
By installing a high quality well designed cold air intake that positions the air intake outside of the hot engine compartment then the engine can draw in colder more dense oxygen rich air. This combined with the gasoline will cause a more intense explosion which will resultin more horsepower, torque and better fuel efficiency.
Now let us look a little at what makes a well designed cold air intake. There are various factors to be considered in the design ofthe cold air intake system such as the diameter of the pipes need to be increased for better air flow, the interior of the intake must be smooth to reduce air resistance, it must provide a more direct route to the air intake, the length of the intake pipes must be tuned for maximum air flow and it must use a more efficient and less restrictive air filter. Intake system come in various configurations and can be made from plastic, metal, rubber or composite materials. A well designed cold air intake is dyno-tested and tuned for a guaranteed high flow performance. Installing this in your vehicle will surely give you an instant power boost all throughout the engine’s rpm range.
Installing Cold Air Intakes
There are several different types of aftermarket High Performance Air Intakes on the market each with its own advantages and disadvantages. Myself I prefer the ColdAir Intake.
The ColdAir intake system relocates the filter outside of the engine compartment to deliver the coldest air inlet temperatures possible. Colder air carries more oxygen, which translates into more horsepower and torque.
Installation Instructions:
- Step 1
Remove the original air intake by removing the piping, air filter and air box. These parts can be removed by using a screwdriver or ratchet and socket on the bolts holding the clamps together. Loosen the clamps and remove the hardware but save the hose clamps. Carefully remove the air sensors from the original intake.
- Step 2
Install the new coldair intake on your Acura Integra by sliding a rubber sleeve over the hole on the intake manifold and fitting the pipe into the sleeve. Tighten the two hose clamps around the rubber sleeve. Another rubber sleep and two more hose clamps will be fitted together in the same manner in the middle of the intake.
- Step 3
Jack up the car and lower it downon to two jack stands. Get under the car to complete the installation by reaching up and placing the filter onto the end of the piping with another sleeve and hose clamp.
- Step 4
Make sure all the hose clamps are tightened and all the rubber sleeves are pushed on properly with no gaps.
- Step 5
Carefully remove the jack stands and lower the car back to the ground.
