Well my Mum drives a 300ZX z31 auto and it is very slow off the line, slow in mid range but does wind up after a while! I used to have a 7m-ge in my MA70 and it had heaps of torque (but was also a 5-speed) and would definately beat the Z31 auto (stock). These motors are pretty underrated, mine used 3lt of oil every 400Km but still went hard! And will always look better than the Z-31! However (and this is for jza70-mel's benefit) with a 1jz-gte and r154 5-speed in it the old MA70 gets no traction in 1st (mainly drifts sideways) when dragging and changing to second causes it to change direction of drift, get traction and launch very hard indeed! (all the way to 100 kph and then changing to 3rd). This is with a completely stock 1jz-gte and a G285 diff (4.30 to 1). The feeling under boost is incredible . My brother was a turbo hating V8 driver until he came for a drive in the Supra! Now he's just a bit jealous.....
