    Die Toyota Supra Community für alle Supra Generationen

    Toyota Supra A90

    Besitzer der fünften Generation des Toyota Supra sind begeistert, denn was Leistung und Fahrdynamik hat der neue Supra A90 alle Erwartungen übertroffen.

    Toyota Supra MKIV

    Bekannt aus dem Fast & Furious Film, kam im Juli 1993 die vierte und bisher letzte Generation des Toyota Supra auf den Markt. International wird dieser Typ "Supra MKIV" genannt.

    Toyota Supra MKIII

    Anfang 1986 wurde die dritte Generation des Supra vorgestellt. Sie ist zugleich die erste, die nicht mehr mit dem Namenszusatz Celica vermarktet wurde.

    Celica Supra (MK2)

    Die zweite Generation wurde im Herbst 1981 präsentiert und hatte mit dem neuen (170 PS) starken 6-Zylinder-Motoren einen komplett eigenständigen Antrieb.

        If the oil clearance is greater than maximum, replace the bearings. If necessary, grind or replace the crankshaft.
        If using a standard bearing, replace with one having the same number. If the number of the bearing cannot be determined, select the correct bearing by adding together the numbers imprinted on the connecting rod cap and crankshaft, then selecting the bearing with the same number as the total. There are 5 sizes of standard bearings, marked ”1”, ”2”, ”3”, ”4” and ”5” accordingly.
