SP80213HP SPower Japan B7HP SOUL II Factory Tuned .21 Racing Engine (Pre-Broken In)

SPower's new factory hand modified, pre-broken-in engine series called “魂II” (SOUL II), is a continuation form the first B7HP SOUL engine. SPower have taken the foundations from the later OS B2105 and amplified everything further to improve power, drivability and efficiency, achieved by taking the conventional 3-Port liner and DLC crankshaft and hand-modifying them for the best possible performance.

In addition to the hand-modified internals, the B7HP SOUL II also features SPower's 'Boost' rear backplate, which helps to increase engine RPM and also idle stability from high RPM-low RPM throttle transition. If this didn't make the engine special enough the B7HP SOUL also comes supplied pre-broken in, minimizing the time from installing the engine to the track.

The stronger DLC coating on new crankshaft has also hand modified with 2 tungsten counterweights contributing to consistent idling and quicker RPM response according to the throttle movements. 

The new printing technology used to manufacture the cooling head also makes for an instantly reocnizable, and colourful appearance to set it out from the crowd when installed in your car.

The factory combo setup with Spower Japan 75mm Exhaust Manifold + EFRA 2089 pipe, B7HP will provide a lot of power for your off road racing needs with the best fuel mileage.
