If you already own a Nissan 300ZX (Z32) you know what a powerhouse it is. In the game of power and performance there is no shortage of after market mods and gadgets. But which ones make a real difference in horsepower?
Here are 9 ways to increase horsepower to your 300ZX (Z32) to consider before you drop a boat load of cash on aftermarket products that may not leave you with your desired results.
Install a cold-air intake. By doing this you increase the amount of airflow into the engine resulting in increased horsepower. Depending on your particular needs a dual cold air intake may also be an option. Consult a knowledgeable tuner to see if you can benefit from this particular modification. This upgrade will give you good bang for your buck.
Install an aftermarket performance exhaust system. This will greatly increase the airflow out of the engine and allow the engine to run more efficiently. This is a relatively inexpensive upgrade and could be done yourself if you are so inclined.
Weight reduction. For every 100 lbs. shed off of your 300ZX you stand to gain or recover 11+ horsepower.Consider removing the rear windshield wiper assembly and replacing the heavy stock seats for some much lighter aftermarket ones. Carbon fiber hoods and hatches are also available which are much lighter than their stock counterparts.
Install a performance computer chip. This will improve overall torque and give you a big boost in horsepower. Some manufactures claim a 60 hp improvement as well as improved gas mileage. The results of this modification greatly depend on the expertise of a qualified tuner who will be writing the program for the performance computer chip.
Turbo upgrade. Well if your 300ZX (Z32) has no turbo’s then this is a must have if you are really seeking power. However if you already have turbo’s then upgrading to larger turbochargers will also be a great benefit.
Balance engine. Gain up to 20 horsepower by balancing the rotational assembly which includes; crank pulley, flywheel and clutch assembly.
Ported and polished cylinder heads. This process is the removal of head material which allows better airflow yielding substantial power gains.
Boost upgrade. Increase the air pressure to the turbo’s to an additional 5 psi. from stock levels. This is accomplished through a specific chip upgrade.
Proper tuning with a dyno. This will fine tune the output performance of your 300ZX by maximizing the peak output and optimizing power output through the entire rpm range.
Looking for more horsepower for your 300ZX (Z32)? These are some of the things that can be done to juice your 300ZX for maximum power. Some are very simple and others may require the expertise of a qualified Nissan 300ZX specialist. Good luck in your power quest and we hope you found this information helpful.
