As per chat with JDMMA70, there are a LOT of things about this car that don't make a lot of sense. If I can just get a photo of the data tag, it would clear SO much up about it. Also any other tags on the car as well.
The 7M-GTE definitely looks like a Turbo A, it has the Turbo A duct as well, but not much else looks like a typical Turbo A. It's hard to know what was done as the car was prepped for various races and/or modified by previous owners. It doesn't have the Turbo A steering wheel, or shift knob, or seats. It doesn't have any Turbo A badging, on the sides or on the rear trim.
It does have the newer body pieces (bumpers, trim, tail lights), but the front turn signals are Euro/Australia style, not Japanese style. The car is way too early for those body panels, production didn't start for 4 more months.
It's either a rare car, or someone has changed a lot of parts onto it. Data tag would answer many questions.
