The Nissan 300ZX Twin-Turbo has one of the most powerful engines created for the best Nissans. This engine makes 300 hp and almost 290 lb-ft. stock torque! The biturbo and intercooler engine is missing very little. Read on to find the 5 most profitable mods to give you the most horsepower for your hard-earned money!

#5

Throttle Body Modification:

The throttle body modification is not going to be the biggest hp gainer in the world, but the best part is that it’s FREE! In case you missed it, yes, it’s completely free! All you need for this modification is a metal file or a 10mm wrench (depending on the 300zx year). All you have to do is simply remove a nut or cast aluminum nub that sits right next to the throttle cable. This bump or nut prevents the throttle from opening all the way. By allowing it to open fully you have increased airflow which increases its power.

#4

Improved air filter:

An upgraded air cleaner is the most basic of all modifications. Adding a higher flow filter will allow your Nissan cars to [http://www.jdm-4u.com/nissan_cars.htm] engine to consume a much higher amount of oxygen than the original air box. Imagine trying to run a mile while using a straw to breathe. It’s not much different for your car if you modify the car and not the air filter.

#3

Improved exhaust system:

An upgraded exhaust system is the same concept as upgrading your air filter. All the air that is being consumed by the engine needs to be evacuated. The problem many people run into is that they do this completely incorrectly. BIGGER IS NOT BETTER! Having an exhaust that is too big for your car will actually hurt your 300zx’s performance. You shouldn’t have more than 3 inches of system unless you plan on running around 1000 hp! This problem is something obvious, but one that very few people think about; the larger exhaust greatly reduces the exhaust temperature. Having a lower temperature means that the air traveling through the exhaust system will be much heavier and therefore more difficult to move, which hurts the performance of the engines. Installing the correct exhaust size will give you the correct exhaust temperature and effectively evacuate air. Contrary to popular belief, a car doesn’t actually lose horsepower because it has a large exhaust due to a loss of back pressure. You lose power with a big exhaust due to turbulence and cold, thick air.

Updated computer chip:

An updated computer chip is one of the easiest modifications. Upgrading the chip will enrich the fuel curve. This gives your car a little more fuel to handle the extra power. Some also say it will help cool down the pistons. In addition to added fuel, the JWT chip maximizes engine ignition timing and also adjusts cam timing. Most chips will have a couple of extra features, like raising the rev limiter to 200 rpm and removing the top speed governor. Having an aftermarket ECU is nice because of the ease of calibration for future modifications like higher boost levels.

#one

Boost Controller or Boost Jets:

Boost controllers and boost jets are the recommended way to increase boost pressure. Adding a boost controller essentially tricks out your wastegates, the wastegates vent boost allows the car to run at 8 psi. The boost controller or boost jets trick the wastegates into thinking there is less boost than there really is, meaning you will have a faster charge time and a large increase in total boost pressure. Boost pressure equals power. Running higher boost pressure is only possible after an ECU update. Investing in a turbo timer is also a good idea when running higher than stock boost, as a turbo timer will help cool down your turbos when it’s time to shut down.

There are plenty of other upgrades for the 300zx, but this one will get you down the road with the least pain in the pocket!
