Why Diesel Spool

A small shop with a big parts room.

We run the same parts on our own builds. If it doesn’t fit, doesn’t flow or doesn’t last, it doesn’t make the catalogue.

  • Fitment checked by a tech before every order ships
  • Genuine parts from authorised distributors
  • Real people on the phone, Monday to Friday

Word from the shop floor

    Average rating from our customers

    Read all reviews

  • Ordered a drop-in turbo for my EcoBoost on a Tuesday and it was on the bench Friday. Spools noticeably sooner than the stocker and holds boost all the way up.

    Marcus D. 2018 F-150 · 3.5L EcoBoost

  • Called about matching a manifold to my turbo and got a straight answer instead of a sales pitch. Everything bolted up first try.

    Tyler R. 2016 WRX · FA20

  • Packaging was serious — double boxed, foam around the housing, hardware bagged and labelled. That tells you how they treat the parts.

    Jesse P. 2020 Civic Type R · K20C1

  • The vehicle filter saved me an hour of cross-referencing part numbers. Picked my year and engine, ordered the intercooler, done.

    Andre W. A90 Supra · B58

  • Had a fitment question two weeks after the install and they still picked up on the first ring. That is rare in this business.

    Nick S. Evo X · 4B11T

  • Third order this year. Prices track the big catalogue sites and parts actually ship when the page says they will.

FAQ

Frequently asked questions

The most popular questions about our work, our parts and choosing the right turbo setup for your build.

What is a turbo kit?

A turbo kit is a complete package designed to upgrade or replace your turbocharging system. Depending on the application, it may include a turbocharger, exhaust manifold, intercooler, charge piping, oil lines, fittings, hardware and other supporting components required for installation. Complete kits simplify the upgrade process by ensuring the major components are designed to work together.

How do I choose the right turbocharger?

The right turbocharger depends on several factors:

  • Engine displacement
  • Desired horsepower
  • Vehicle usage (daily driving, towing, racing)
  • Fuel system capability
  • Supporting modifications

Choosing a turbo solely based on size is not recommended. An oversized turbo may produce more peak power but often sacrifices spool response, while an undersized turbo may spool quickly but limit horsepower. Garrett recommends selecting a turbo based on realistic horsepower goals and compressor map matching.

Will a larger turbo increase horsepower?

Yes — provided the engine, fuel system, tuning and supporting hardware can supply the additional airflow and fuel required.

A larger turbo generally offers:

  • Higher airflow capacity
  • Increased horsepower potential
  • Lower exhaust backpressure at higher power levels

However, larger turbos often spool later than smaller units, so selecting the correct size is important for your intended use.

Do I need supporting modifications for a turbo upgrade?

In many cases, yes. Depending on your horsepower goals, recommended supporting upgrades may include:

  • Larger intercooler
  • Improved intake system
  • Higher-flow exhaust components
  • Fuel system upgrades
  • ECU calibration
  • Boost control components

Supporting modifications help maximize performance, improve reliability and maintain safe operating temperatures.

How does an intercooler improve performance?

Compressing air with a turbocharger increases its temperature. An intercooler cools the compressed air before it enters the engine, resulting in:

  • Higher air density
  • Improved combustion efficiency
  • Lower intake temperatures
  • Reduced risk of detonation (where applicable)
  • More consistent performance under load

Garrett recommends selecting an intercooler based on horsepower goals and available packaging space.

What are the benefits of an upgraded exhaust manifold?

Performance exhaust manifolds are designed to improve exhaust gas flow to the turbine. Potential benefits include:

  • Improved turbo response
  • Better exhaust flow
  • Reduced flow restriction
  • Increased durability under high temperatures
  • Better support for larger turbochargers

Performance gains depend on the complete turbo system rather than the manifold alone.

What’s the difference between a wastegate and a blow-off valve?

Although both are pressure-control devices, they perform different functions.

Wastegate

  • Controls turbo speed
  • Regulates boost pressure
  • Diverts exhaust gases around the turbine

Blow-off valve (BOV)

  • Releases excess boost pressure when the throttle closes
  • Helps prevent compressor surge
  • Protects the turbocharger during rapid throttle changes

They are installed in different locations and serve different purposes within the turbo system.

Can I install a performance turbo on a stock engine?

Many mild turbo upgrades are compatible with stock engines. However, higher horsepower builds may require:

  • Engine strengthening
  • Fuel system upgrades
  • Improved cooling
  • Professional tuning

Every application is different, so compatibility should be evaluated based on your specific vehicle and performance goals.

Which diesel trucks do your performance parts fit?

Diesel Spool offers components for many popular diesel platforms, including:

  • Ford EcoBoost
  • Honda
  • Subaru
  • Toyota
  • BMW
  • Mitsubishi
  • Nissan
  • Volkswagen / Audi

Availability varies by product category and model year. Always verify vehicle compatibility before ordering.

How do I know if a turbocharger is compatible with my vehicle?

Compatibility depends on factors such as:

  • Engine model
  • Turbo mounting flange
  • Exhaust manifold design
  • Compressor outlet configuration
  • Intended horsepower
  • Supporting modifications

Our product pages include fitment information, and our team can help recommend the correct solution for your build.

Which brands does Diesel Spool offer?

We carry performance components from trusted manufacturers known for engineering quality and reliability, including premium turbocharger and performance brands used by enthusiasts and professional builders.

Available brands may vary by product category.

Do turbo upgrades improve towing performance?

When properly matched to the application, a turbo upgrade can improve towing performance by providing:

  • Better torque delivery
  • Improved airflow
  • Reduced exhaust backpressure
  • More consistent power under load

For towing-focused builds, turbo selection should prioritize response and usable torque rather than maximum peak horsepower. Garrett specifically recommends selecting the turbo based on the vehicle’s intended use.

How should I maintain a performance turbocharger?

Turbochargers generally require no special maintenance beyond proper engine maintenance. Best practices include:

  • Follow recommended oil change intervals
  • Use high-quality engine oil
  • Replace air filters regularly
  • Ensure unrestricted oil supply and drain lines
  • Inspect charge piping and clamps periodically
  • Check for boost leaks during routine maintenance

BorgWarner notes that a properly maintained turbocharger is designed to last as long as the engine under normal operating conditions.

Why choose Diesel Spool?

At Diesel Spool, we focus on premium turbo performance components selected for quality, fitment and real-world reliability.

Whether you’re replacing an OEM turbocharger or building a complete high-performance setup, our goal is to provide trusted products, knowledgeable support and components engineered to help your diesel perform at its best.
