Q: How do I know if a particular turbo will fit and work on my car? A: We try to make the turbo purchasing and upgrading as easy as possibly by categorizing our turbos by auto manufacturer and brand. Occasionally, some brands and manufacturer parts are cross-compatible. If you have a question about fitment of a specific turbo, please feel free to call or email us. Q: Do I need any other modifications when installing an upgraded or aftermarket turbo? A: Anytime you install a turbo on a naturally aspirated vehicle, or upgrade the stock turbo(s), it's important to upgrade the supporting factions of your car's fueling system. What needs upgrading will vary greatly from car to car; anything from injectors, to fuel pumps, or engine management. The determining factor will be the goals for your car. Give us a call and let us help plan your project. Q: What size turbo should I choose? A: This again, depends on the goals you have for your car, as well as other factors such as engine strength and engine displacement. If your goal is make a reliable, daily-driven 250whp Civic, you probably don't need one of our PT101 turbos, which is capable of 2100hp. Additionally, using an extremely large turbo on a small displacement engine, will make for a very short, unusable powerband. This is another area we are pleased to help you with in making a decision, so give us a call or shoot us an email.
