Engines with the sooner HLA are proposed to use 10W30 or 10W40 oil calendar year-spherical; 5W30 may be used at pretty very low winter temperatures. The roller rocker cam follower method that was released on the Impreza engines, is put in on all 1996 model yr and afterwards engines. The roller assemblies aren't serviceable individually, even so the rocker arms may very well be serviced as person units.

The freedom RS disappeared from showrooms during 1994. In 1994, the initial Australian spec WRX was released. Like its Japanese cousin, the Rex engine utilizes an air-to-air intercooler and a large potential turbo – but, however, the Australian-spec engine trails by a considerable margin.
Alter the ECU appropriately, and you will reach 350HP or more – an exceptionally wonderful ceiling for your EJ207 inventory internals.
