That Edition of your engine used Hydraulic Lash Adjuster (HLA) heads, was suggested to get operate on ninety one octane gas, had decreased energy and torque rankings as opposed to later on 1997-1999 EJ25D, and was only presented with an automated transmission. In 1997 a revised engine was released that utilised heads with shimmed bucket lifters (as opposed to the HLAs), was meant to operate on 87 octane gas, and was accessible with possibly a manual or automated transmission.

During the STi selection, Australia first gained the MY99 Version five two-doorway and MY00 Edition 6 4-doorway models. These engines retain the Japanese-spec mechanicals but are detuned to suit Australian gas read more – so real output is most likely a lot less than the claimed 206kW/353Nm.
Subaru specifies utilizing its Super Coolant or an equal that fulfills its high quality benchmarks with the EJ20 engine. This sort of coolant is typically ethylene glycol-dependent with additives that guard towards corrosion.

Ninety-8 RON unleaded is suggested for this engine and, for The 1st time, a sequential computerized transmission was launched.
