MKIII as in Mark three, the third Generation Toyota Supra Of Toyotas A chassis of sport cars. The early models carried the last of Toyotas M family of Inline six the 7M-GE (Non-turbo)and 7M-GTE (Turbo). The M motors and the cars which carried them, stems from Toyotas racing legacy which all began back in 1965 with the introduction of the Toyota 2000 GT, Japans real first Sports Car.
Prior to 1991 Toyota sold the Turbo A supra, which ran the 7M-GTEU motor, a modified version of the standerd 7M-GTE. The Turbo A cars where all black, with the standard "See Saw" rims powder coated Gun Metal. The Turbo A Supras where a Limited Edition model where only 500 were ever where made, the creation of this model was aimed towards Privateer racers who where racing in Grand Touring racers all thru out the world besides North America. Before the Production of the Nissan Skyline GT-R, the Turbo A Supra was the fastest Japanese production car in existence.
The creation of the Nissans Skyline GT-R, opted Toyota to introduce the 1JZ-GTTE Twin Turbo motor. The Supra Turbo R JZA70, as it became to be known, hit the streets to show off toyotas engineering feet of Twin Turbo technology, in hopes of sharing Nissans quest of fighting German Engineering.
Sadly the likes of the 1JZ-GTTE, never came to America. The last models sold in America from 91' to 92'continued to receive the outdated and restricted USDM 7M-GE and 7M-GTE engines.
Today the MKIII, or MA70 as JDM enthusiast like to put it, can be had for $2000-$5000 depending on the condition and mileage. Cars that are bought with over eighty-thousand miles, should have the head gasket replaced with an aftermarket unit and specifically ARP head bolts or studs. As the factory settings of 53psi to bolt down the head isn't up to par for even the mildest drivers.
Long and steady, these cars are fun tuner build ups. Without as much aftermarket support as the MKIV JZA80 supra, E-Bay searches could find an enthusiast rare HKS tuning parts which have been discontinued in Japan for over a decade.
The besides the head gasket troubles, the 7M motor is very sound. The 3000 intake pipe and throttle body may be a hassle for some when it comes to basic maintenence, but all in all these cars where built right.
People who have modified and tune these motors have been know to reach over 600 horse power on the stock bottom and of course with a stronger head gasket with a little bit of work on the top end.
