The foundation of a reliable race motor is in the block, pistons, and rods. These 3 major components of the motor take the most abuse and are exposed to the most stress. If you plan to target more than 300HP from your Subaru engine you must reinforce engine block components, assuming you want a long lasting motor. At Outfront we have focused on this area of the Subaru infrastructure and solved these weak links with all the parts you need to build an exciting power plant without sacrificing reliability. These component and block technologies are common place in the racing world, such as CART, NASCAR, and IRL. At Outfront we have simply adapted this common racing technology to the Subaru boxer engine, and it works absolutely awesome.

Outfront also offers complete rebuild services of your block and heads. Valve jobs are also available from $350 and up. All gaskets, bearings, plastics, cam gears, water pumps, etc. all in stock!
