1990 Toyota Supra Service and Repair Manual
Toyota's 1990 Supra ran a single 3.0-liter inline-six in two states of tune: the naturally aspirated 7M-GE and the turbocharged 7M-GTE, each a 2954cc DOHC unit. Both were offered with an automatic or a standard transmission, giving the six build combinations recorded for the year.

Known issues on the 1990 Supra. NHTSA records 4 owner complaints, and Toyota has issued 6 technical service bulletins covering the car.
Both engines share the same 2954cc displacement and DOHC layout, so what separates one 1990 Supra from the next is induction and transmission: naturally aspirated or turbocharged, automatic or one of the two standard-transmission builds listed above. Pinning a car to one of those six combinations is the first step in any procedure on it.
