2016 Nissan Altima 2 5 SR Mods to Begin

Altima Mods Overview

The Nissan Altima and Altima Coupe may not be the fastest cars, but they offer great potential for upgrades. Let’s dive into the best mods for the Altima’s 2.5 and 3.5 engines, covering tuning, intake, exhaust, headers, pulleys, and turbo kits.

1. Tuning: Unleashing Potential

Tuning is a crucial aspect of performance upgrades. While off-the-shelf options might not be readily available for Altima 2.5 and 3.5 engines, tuning becomes more valuable with additional mods like headers, throttle bodies, and cams. Altima tunes can yield gains of 10-20 horsepower when combined with other enhancements.

2. Cold Air Intake: Breathing Fresh Power

An intake upgrade is a standard choice for car enthusiasts, offering gains of 3-10 horsepower, improved torque, better throttle response, and enhanced engine sounds. Altima intake mods contribute significantly to power gains, especially with straighter piping, optimizing air flow.

3. Exhaust Mods: The Sound of Power

Upgrading the exhaust system, including cat-backs, axle-backs, and y-pipes, brings 5-10 horsepower gains, improved torque, and a more distinctive engine/exhaust sound. While exhaust upgrades are beneficial, considering the cost relative to power gains is crucial.

4. Headers: Bang for Your Buck

Headers, or exhaust manifolds, offer one of the best power-to-cost ratios among Altima mods, providing 8-15 horsepower gains, similar torque improvements, and an enhanced engine sound. While DIY installation might be challenging, the benefits justify the effort.

5. Pulley Upgrades: Reducing Rotational Mass

Pulley upgrades reduce rotational mass, making it easier for the engine to drive the belt and pulley. Although gains are modest (3-7 horsepower and torque), these upgrades are cost-effective, with options available from manufacturers like 2J-Racing and Stillen.

6. Turbo Kit: Serious Power Mods

While not delving deep into turbo kits, they represent a gateway to substantial power mods for Altima engines. Naturally aspirated engines like the 2.5L and 3.5L can benefit from forced induction, but costs and complexities increase. Turbo kits are recommended for those seeking gains exceeding 50whp.

Power Goals and Mod Combinations

Combining specific Altima mods allows you to achieve various power goals. Let’s explore potential upgrades for different power gains.

a. 10-20whp Gains (~$1,000)

  • Intake
  • Pulley
  • Tune

These mods, achievable for around $1,000, can provide at least 10whp gains, with potential variations based on the engine type.

b. 20-30whp Gains (~$1,500)

  • Intake
  • Pulley
  • Headers
  • Tune

Adding headers to the mix can bring total gains to around 20-30whp, with variations depending on the engine.

c. 30-40+whp Gains ($2,000+)

  • Intake
  • Pulley
  • Headers
  • Tune
  • Exhaust
  • Throttle body
  • Cams (optional)
  • Forced induction (optional)

For enthusiasts seeking substantial gains, this comprehensive list covers basic bolt-on mods. Beyond this point, more serious mods like cams, turbo or supercharger kits, become essential.

The Altima’s Modding Potential

The Nissan Altima may not be the first choice for many modding enthusiasts, but it proves to be a versatile and fun car to modify. With basic bolt-on mods, you can unleash 10-30whp, thanks to a tune, intake, exhaust, headers, and pulleys.
