 This version was to be the most powerful Celica produced to date, producing between for the export model and for the Japanese market model from an updated 3S-GTE engine matched to the E154F gearbox.Influenced strongly by Toyota Team Europe, Toyota's factory team in the World Rally Championship, the final version of the GT-Four included improvements such as an all-aluminum hood to save weight, four-channel ABS (optional for the Japanese market), an improved (enthusiast dubbed) CT20B twin entry turbocharger, and "Super Strut Suspension".The 2500 units homologation cars built to allow Toyota to enter the GT-Four as a Group A car in the World Rally Championship also featured extras such as all of the plumbing required to activate an anti-lag system, a water spray bar and pump for the front intercooler, a basic water injection system, a small hood-mounted spoiler aft of the windscreen washers (also standard fit on all UK cars) and an extender rear spoiler mounted on risers.
