How To Increase Your Vehicle's Performance in Your Own Garage

You can invest over $700 for a 350 TBI performance kit to upgrade your 90s small block engine, or you can start with smaller, more affordable projects. The beauty of making upgrades to your vehicle is that most performance upgrades only require a DIY skill set. That's right, with some spare time and enough space in your garage, you can improve your vehicle's power and performance.

Change the Air Intake

Every car engine is essentially a robust air and fuel pump. If you want more power, you need to improve the airflow into the engine. The more air your vehicle takes in, the more fuel the system's computer mixes with it, creating more power.

A cold-air intake can dramatically improve horsepower and performance. Not only does this intake increase air flow, but it also pulls in oxygen-rich and denser air from outside of the engine compartment. The better quality air requires even more fuel, allowing for more power.

Upgrade the Exhaust System

If you are going to replace the air intake, you should upgrade the exhaust system. A better-quality intake pulls in more air, but it can only push as much air through as the exhaust allows. Upgrading to a cat-back system with larger diameter piping will improve airflow throughout the system, allowing for a power and performance boost.

Install a Larger Diameter Throttle Body

Before spending money on a new 351M carburetor, consider installing a larger diameter throttle body. The throttle body sits between the air intake and engine manifold and helps regulate the airflow into the engine. A larger diameter throttle body will permit more air to flow into the engine, which maximizes the performance of the new cold-air intake you installed.

Invest in a New Catalytic Converter

Before diving into a debate on catalytic converters, know that your vehicle's standard part is likely fine. That said, upgrading to a high-flow option can improve airflow through the system, allowing for a more efficient driving experience. A high-flow option will complement the above upgrades, ensuring you get the most out of each addition.

Use a Performance Tuner

If you don't mind messing with your vehicle's fuel economy, you can use a performance tuner. The device plugs into your diagnostic port and works by remapping existing timing and fuel maps. The expense of fuel economy may be worth it to some drivers, but for most people, it's not, especially when you consider the gains are likely minor.

Install a Boost Controller

A boost controller is another component you can probably install in your garage, and it is only for turbocharged or supercharged engines. The controller allows you to manipulate factory presets to achieve a stronger performance boost. You should be careful and use a boost gauge if you install a controller because it is easy to overdo it and damage your engine.

You can buy performance-enhancing kits like the 5.7 TBI power package, or you can make smaller upgrades, a little at a time. Before making any upgrades to your vehicle, talk to an automotive professional.
