That version on the engine utilised Hydraulic Lash Adjuster (HLA) heads, was suggested to generally be run on ninety one octane gasoline, had reduce electricity and torque ratings than the later on 1997-1999 EJ25D, and was only provided with an automated transmission. In 1997 a revised engine was launched that employed heads with shimmed bucket lifters (in lieu of the HLAs), was built to run on 87 octane fuel, and was available with possibly a guide or automatic transmission.
