Choosing the Right Turbo for Your SR20: Your Ultimate Guide
Upgrading your Nissan SR20 engine with a turbocharger can unlock serious power and exciting performance. But with so many options, picking the right one can feel overwhelming. This guide will help you understand what to look for and make the best choice for your SR20.
What to Look For: Key Features of a Great SR20 Turbo
When you’re shopping for an SR20 turbo, keep these important features in mind:
- Size (A/R Ratio): This is how much air the turbo can push. Smaller turbos spool up faster, meaning they start boosting sooner. Bigger turbos make more power but take longer to get going. For street cars, a good balance is key.
- Horsepower Rating: Turbos are rated for the amount of horsepower they can support. Make sure the turbo you choose can handle the power you want to achieve.
- Ball Bearing vs. Journal Bearing: Ball bearing turbos are more durable and spool faster. Journal bearing turbos are simpler and often cheaper.
- Internal vs. External Wastegate: A wastegate controls how much boost your turbo makes. Internal wastegates are built-in and simpler. External wastegates offer more precise boost control.
- Flange Type: This is how the turbo bolts to your exhaust manifold. Make sure it matches your manifold or that you have the right adapter.
Important Materials: What Your Turbo is Made Of
The materials used in a turbocharger affect its strength and how well it works.
Turbine Wheel and Compressor Wheel
- Most high-quality turbos use strong, heat-resistant materials like Inconel for the turbine wheel. This part gets very hot.
- The compressor wheel is often made from lightweight aluminum alloys.
Housing
- Turbo housings are usually made from cast iron. This metal handles high temperatures and pressure well.
Quality Matters: Factors That Improve or Reduce Turbo Quality
Not all turbos are created equal. Here’s what makes a big difference:
Factors That Improve Quality:
- Brand Reputation: Well-known turbo brands often use better engineering and materials.
- Manufacturing Precision: Tightly made parts mean less friction and better airflow.
- Advanced Designs: Some turbos have special designs that help them spool faster or handle more air.
Factors That Reduce Quality:
- Cheap Materials: Using lower-quality metals can make a turbo less durable and prone to failure.
- Poor Balancing: If the spinning parts aren’t perfectly balanced, the turbo can vibrate and break.
- Improper Design: A turbo that’s too big or too small for your engine can cause problems and not perform well.
User Experience and Use Cases: How You’ll Use Your Turbo
Think about how you want your SR20 to perform.
Daily Driving
- For a car you drive every day, you’ll want a turbo that spools up quickly. This means less waiting for power.
- A smaller turbo with a good A/R ratio is usually best for street use. It gives you good response without being laggy.
Track Days and Racing
- If you’re building a race car, you might want a bigger turbo. This lets you make a lot of horsepower.
- You might need more supporting mods for bigger turbos, like upgraded fuel injectors and a better engine management system.
Budget Builds
- For a more affordable upgrade, you might look at journal bearing turbos. They are less expensive but might not last as long or spool as fast.
- Used turbos can be an option, but inspect them very carefully for damage.
SR20 Turbo FAQs: Your Burning Questions Answered
Here are answers to some common questions about SR20 turbos:
Q: What is the most popular turbo size for an SR20?
A: Many people choose turbos in the 250-350 horsepower range for a good balance of street performance and power. Sizes like the Garrett GT28RS or a similar unit are common.
Q: Do I need to upgrade anything else when I install a turbo?
A: Yes, you often need to upgrade your fuel system, exhaust, and engine management (ECU). This ensures the engine gets enough fuel and air, and that the turbo runs safely.
Q: How long does an SR20 turbo usually last?
A: With proper care and maintenance, a good quality turbo can last for many years and thousands of miles. Regular oil changes are very important.
Q: What does “turbo lag” mean?
A: Turbo lag is the delay you feel between pressing the gas pedal and the turbo starting to produce boost. Smaller turbos have less lag.
Q: Can I put a turbo on a naturally aspirated SR20?
A: Yes, you can, but it’s a big job. You’ll need many special parts, and it’s often more complex than starting with a factory turbo SR20 engine.
Q: What’s the difference between a turbo and a supercharger?
A: Both force more air into the engine. A turbo uses exhaust gases to spin a turbine. A supercharger is driven by the engine’s crankshaft.
Q: Is it safe to buy a used turbo?
A: It can be, but you must check it very carefully. Look for shaft play, damaged fins, and leaks. A professional inspection is a good idea.
Q: What is the A/R ratio on a turbo?
A: The A/R ratio describes the size of the volute (the snail-shaped housing) on the turbo. A lower number means a smaller opening, which helps the turbo spool faster.
Q: How much boost can my stock SR20 engine handle?
A: Stock SR20 engines can usually handle about 7-10 PSI of boost safely. For more, you’ll need stronger internal engine parts.
Q: Where can I buy an SR20 turbo?
A: You can find SR20 turbos at online performance parts stores, specialty automotive shops, and sometimes from other enthusiasts.
