| The Nissan 300ZX Twin-Turbo has one of the most | | | | lower temperature means the air traveling through the |

| VG30DETT has huge amounts of potential. This | | | | harder to move, which hurts your engines |

| effective modifications to give you the most | | | | many think, a car doesn’t actually lose horse |
| horsepower for your hard earned dollar! | | | | power because it has a large exhaust because of a |
| #5 | | | | loss of back pressure. It looses horsepower with a |
| Throttle body modification: | | | | large exhaust because of turbulence and the cold |

| it’s FREE! In case you missed that, yes, its | | | | Upgraded computer chip: |
| completely free! All you need for this modification is a | | | | An upgraded computer chip is one of the easiest |
| metal file or a 10mm wrench (depending on what year | | | | modifications. Upgrading the chip will enrich the fuel |
| 300zx). All you have to do is simply remove a nut or a | | | | curve. This gives your car a bit more fuel to support |
| bump of molded aluminum that is sitting right by your | | | | the added power. Some also say it will help cool the |
| throttle cable. This bump or nut is preventing your | | | | pistons. In addition to the added fuel, the JWT chip |
| throttle from being able to open completely. By allowing | | | | maximizes the engine's ignition timing and also tunes |
| it to open completely you’ve increased your air | | | | the cam timing. Most of the chips out there will have a |
| flow which increases your horse power. | | | | couple additional features like raising the rev-limiter 200 |
| #4 | | | | rpm, and eliminating the top speed governor. Having an |
| Upgraded air filter: | | | | aftermarket ECU is nice because of the ease of |
| An upgraded air filter is the most basic of all | | | | calibration for future modifications like higher boost |
| modifications. Adding a higher flow filter is going to | | | | levels. |
| allow your Nissan cars [ engine to consume a much | | | | #1 |
| larger amount of oxygen then the stock air box. | | | | Boost controller or boost jets: |
| Imagine attempting to run a mile while using a straw to | | | | Boost controllers and boost jets are the |
| breath. It’s not a lot different for your car if you | | | | recommended way to increasing your boost pressure. |
| modify the car and not the air filter. | | | | Adding a boost controller essentially tricks your waste |
| #3 | | | | gates, waste gates vent boost allowing the car to just |
| Upgraged exhaust system: | | | | run at 8 psi. The boost controller or boost jets trick the |
| An upgraded exhaust system is the same concept as | | | | waste gates into thinking that there is less boost than |
| upgrading your air filter. All the air that is being | | | | there really is meaning you will have a quicker spool up |
| consumed by the engine needs to be evacuated. The | | | | time and a large increase in total boost pressure. |
| problem that many people run into is they go about | | | | Boost pressure equals power. Running higher boost |
| doing this the completely wrong way. BIGGER IS NOT | | | | pressure is only capable after an ECU upgrade. |
