Some folks just can't resist improving on a great thing, like constantly fine - tuning a high - performing car. That's exactly the spirit at Blouch Performance Turbo. We just had to tweak the 'Polka Pickle' to get even more power out of it! To boost its performance, we equipped the Pickle with a 10cm2 turbine housing. This reduces turbine inlet pressure and cuts down on engine pumping losses. We also used the latest 'XT - R' fully - machined billet compressor wheel technology. It optimizes the airflow of this turbo and increases compressor flow to 49 lbs/min, all within the same inducer geometry. This turbo combines state - of - the - art Garrett GT turbine and full ball bearing technology. It comes as a complete bolt - on package, including a braided stainless steel turbo oil feed line, oil feed restrictor, turbo oil drain tube, coolant lines, and turbo mounting gaskets. The Dominator 2.5XT - R has a standard adjustable upgrade actuator, pre - calibrated to work at 15 PSI unless you ask for something different. You can also choose a black ceramic coated turbine housing and a 3' bellmouth inlet compressor housing. Does it perform? Absolutely! It spools up quickly, has a wide and flat torque curve, and delivers amazing peak horsepower that keeps pulling. If your goal is 490 crank horsepower for your EJ25 engine, the BPT Dom 2.5XT - R is the perfect choice. Application: Subaru WRX/STi. Horsepower: 490HP. Specs: Garrett Ball bearing CHRA, 60mm Turbine Wheel, 71mm XT Compressor wheel, 49lbs per min, 8cm or 10cm Exhaust housing available.
Using this Blouch Dominator 2.5 XT - R turbo is straightforward. It's a bolt - on package, so you can easily install it on your Subaru WRX or STI. Just make sure to connect all the included parts like the oil feed line, drain tube, and coolant lines properly. When it comes to the adjustable actuator, it's pre - set to 15 PSI, but you can adjust it according to your needs. However, if you're not familiar with turbo tuning, it's a good idea to consult a professional. For maintenance, regularly check the oil level and the condition of the oil feed and drain lines. The turbo's ball bearings need proper lubrication, so make sure the oil is clean and at the right level. Also, keep an eye on the coolant lines to prevent overheating. If you choose the black ceramic coated turbine housing, it's more resistant to heat, but still, avoid extreme heat situations for long periods. In general, with proper use and maintenance, this turbo will serve you well and help you reach your 490 - horsepower goal.
