The 2.0 liter FA series flat four is derived from the Subaru Forester 2.0XT and is an excellent candidate for power upgrades
Shanghai, China (PRWEB) August 29, 2014
P&A International, a die casting China based company, has just announced that is has joined forces with a leading aftermarket and race car parts designer and manufacturer to develop high end tuning solutions for Subaru racing teams. As part of this collaboration, a leading Subaru WRX tuning company is working with P&A International in order to finalize the development and production of the comprehensive turbocharger upgrade kit for the 2016 Subaru STI and later WRX models.
As a company spokesperson for P&A International explained, the company has been contracted to manufacture the cast aluminum intake manifold for the new boxer 4 cylinder 2.0L and 2.5L engines.
“The 2.0 liter FA series flat four is derived from the Subaru Forester 2.0XT and is an excellent candidate for power upgrades,” the spokesperson explained, adding that the new intake manifold consists of intricate custom die casting and precision CNC machined parts that are put together to form variable intake manifold that will enhance engine volumetric efficiency to peak at two points: 2500 RPM and 6500 RPM.
“This is done via changing geometry of the intake tract known as pulse tuning.”
The design that P&A International is working on is focused on mild and large turbocharger upgrades where the 2500 RPM point is used to assist with the turbocharger spool, bringing down the turbo spool threshold some 500 RPM, which also allows the engine to operate efficiently in full power output near redline in high demand scenarios.
“The assembly will consist of aviation grade aluminum intake with custom electronic control module and an enlarged throttle valve,” the spokesperson said, adding that there will be provisions at each port for water-methanol injectors supplied by UK-based business Aquamist, as well as provisions for NOS.
“The same intake manifold will be available in carbon fibre for race applications but tuned for max VE at 4500 RPM and 8500 RPM.”
