Using your Boost Lab TD05H - 20G turbocharger is simple. First, make sure your vehicle is in the fitment list, like a 2008 - 2014 Subaru WRX EJ25, 2005 - 2009 Subaru Legacy 2.5GT, or 2009 - 2013 Subaru Forester XT. Then, use the included gaskets and hardware for a seamless installation. When you start driving, you'll notice the improved power and performance.
Here are some important notes. Don't push the turbo beyond its limits right away. Let it warm up a bit before going full throttle. Also, make sure to use the right type of fuel as recommended. If you use pump gas, you can get up to 400hp, but if you want more power, race gas or E85 can be a good option.
For maintenance, check the turbo regularly for any signs of wear and tear. The turbo is VSR balanced and tested, but it's still a good idea to have it inspected by a professional once in a while. And remember, it comes with a 1 - year/unlimited mile warranty, so if there are any issues, you're covered.
