A shinning star of the import world, the Subaru Impreza is nearly unstoppable. These rally-bred machines are able to deliver a totally new experience in acceleration and handling. Here we have the rundown on a mean-looking Impreza ver 8, ‘wrenched’ to near perfection in terms of performance by the guys at ST Wangan. Much like everything that comes out of ST Wangan’s accented garage, this Impreza is seen to have been given the ‘wrench’ with meticulous care.
Getting a facelift and a Varis CF hood surely isn’t the end of the mod story for this featured Impreza ver 8, as you’ll see. The facelift with a version 9 kit surely adds some points to its appearance with an up-to-date look for this Impreza, although the consequence is that it makes the stock BBS wheels look microscopic. In a crowd of forged Japanese rims, the owner has opted for a set of Rays RE30 partnered with a set of 235/40R17 Advan Neova tyres.
In achieving a nice performance setup with powerbands suitable for the streets, a few mod and upgrading were done onto the EJ-20 engine. All these were achieved without taking any chances in the reliability department, which has always been taken into consideration. Looking at the list of mods done, I’d say the use of a re-flashed or re-mapped E.C.U with a more suitable fuel mapping that keeps the vital mixture of fuel, air and spark consistent play an important role in the performance upgrading of this EJ-20 engine. The upgraded 255lph Walbro fuel pump was handed the task of feeding fuel while the SARD fuel pressure regulator manages the supply. Airflow capability for this EJ-20 is further enhanced with the presence of a complete HKS Racing suction kit while a HKS SSQV blow-off valve thwarts compressor surge. Among other added items include the Tomei timing belt guide and Power Enterprise belting…
