350z Rebuild Kits - Unlock Hidden Horsepower Potential

Upgrading Your Nissan 350z

The Nissan 350z is a legendary sports car that has been popular with driving enthusiasts ever since its introduction in 2002. As a rear wheel drive coupe with a powerful 306 horsepower V6 engine, the 350z offers an exciting driving experience right out of the box. However, many 350z owners choose to upgrade and customize their vehicles to extract even more power and improve handling and braking. One of the most popular ways to upgrade a 350z is by installing a rebuild kit.

What is a 350z Rebuild Kit?

A 350z rebuild kit refers to a collection of parts that are designed to withstand much higher levels of power and stress than the factory installed components. Rebuild kits are commonly focused on core areas of the engine such as the rotating assembly, valvetrain, and oiling system. Upgrading these components allows the engine to spin faster, breathe deeper, and stay lubricated under demanding driving conditions.

Key Components of a Rebuild Kit

Some of the most important components found in 350z rebuild kits include:

• Forged pistons
• Performance connecting rods
• A billet steel crankshaft
• Upgraded engine bearings
• High flow oil pump
• Reinforced timing chain
• Double valve springs
• Titanium retainers

These parts work together to unlock more horsepower from the VQ35DE engine while also enhancing durability for high RPM operation or forced induction setups.

Benefits of a Rebuild

Some of the major benefits 350z owners can enjoy from installing a rebuild kit include:

• Higher horsepower output
• Increased throttle response
• Redline boost from 6600 RPM to 7500 RPM+
• Improved engine reliability under boost or at the track
• Opens the door for more aggressive turbocharged or supercharged builds
• Unleash the full potential of your Z!

Important Considerations for Your Rebuild

While rebuild kits provide a great starting point, there are some important considerations to factor in for your 350z upgrade path:

Set a Horsepower Target

First, determine a realistic power goal for your Z based on how you want to use the vehicle. A mild 400 horsepower build is much different than a 700+ horsepower twin turbo monster! Match your components to your goals.

Factor in Supporting Mods

In addition to engine internals, you may need to upgrade fuel system components, ignition system parts, cooling system hardware, drivetrain, and more to handle the power. A total vehicle approach is crucial for both safety and performance.

Work with a Qualified Shop

Even simple rebuild kits require special tools and expertise to install properly. Working with a qualified racing shop ensures correct assembly and tuning.

Set Aside Funds for Tuning

Turbocharged and high compression naturally aspirated builds require in-depth ECU tuning to run cleanly and avoid detonation on pump gas. Budget for a quality tune.

Expert Brands and Sourcing Quality Hardware

Investing in a complete, high end rebuild kit from a respected manufacturer goes a long way in providing carefree and reliable high horsepower. Some of the top brands in 350z rebuild kits include:

• Wiseco - The gold standard for forged pistons
• Eagle - Leading rods and crank provider
• Ferrea - Valvetrain and tuning experts
• Mishimoto - Killer cooling system upgrades
• CP Carrillo - Precision engine internals

Combining parts from multiple manufacturers allows you find the ultimate blend of performance, durability, and value. Work closely with your chosen performance shop to source quality components that align with your rebuild budget.

Unlocking Your 350z's Full Potential

A complete rebuild kit offers the keys to transforming your 350z from merely quick to extraordinarily fast. With an upgraded bottom end, cylinder heads, and all supporting mods, you can push your Z deep into supercar-humbling territory. If you're ready to experience the ultimate in Nissan VQ engine performance, a rebuild could be the perfect solution!

FAQs

What's the easiest way to add 100+ horsepower to my 350z?

Installing a rebuild kit with forged internals allows you to safely increase boost pressure or compression substantially to pick up big power gains from your VQ35DE engine. Supporting fuel system and tuning mods maximize the results.

What kind of budget do I need for a rebuild?

The engine internals alone usually cost between $3,000 to $6,000 depending on the brands and hardware chosen. With all supporting mods such as injectors, fuel pumps, intercoolers, etc - plan on investing $8,000 to $15,000 for a comprehensive 500+ horsepower turbo build.

Can I install a rebuild kit myself?

While advanced enthusiasts can install rebuild components themselves, extensive special tools and machining experience is required. You're better off having a professional race shop handle the rebuild installation.

How much will my car be down during the rebuild process?

If the block needs extensive machining and parts sourcing, the entire rebuild process can take 4-8 weeks. Some shops provide loaner vehicles so your daily driver isn't out of commission for too long. Communicate expected timelines upfront.
