You know how some people just cannot leave a good thing alone? Kinda like continually tweaking on a performance car when it already runs great. Well, that's how it is at Blouch Performance Turbo and we couldn't resist tweaking the "Polka Pickle" to squeeze a little more "juice" out of it ;0).

In order to "juice" it up, we gave the Pickle a 10cm2 turbine housing to reduce turbine inlet pressure and engine pumping losses. Next, we took advantage of the latest "XT-R" fully-machined billet compressor wheel technology to optimize the aero of this little cucumber and increase compressor flow to 49 lbs/min within the same inducer geometry.

All of this combined with a custom high flow low inertia turbine wheel and low friction low inertia ceramic ball bearing technology to produce a complete bolt-on package that includes braided stainless steel turbo oil feed line, oil feed restrictor, turbo oil drain tube, coolant lines and turbo mounting gaskets. Adjustable upgrade actuator is standard issue on the Dominator 2.5XT-R and is pre-calibrated to operate at 15 PSI unless otherwise specified. Options includes black ceramic coated turbine housing and 3" bellmouth inlet compressor housing.

So does it dance? You bet is does - quick spool, a nice broad flat torque curve and awesome peak horsepower that just keeps on pulling. If 490 crank horsepower is the target for your EJ25, the BPT Dom 2.5XT-R is for you!
