nice installations but I would prefer to keep my driveshafts dead straight at resting position, the position in which the engines are mounted forces the dshafts to be run a little out of alignment, it works but its a little off, can cause long run troubles. to properly align the engine I always make mounting plates bolted to the chassis - the original 3s mounts are too weird no matter if they come from a camry, celica, mr2 or corona
I currently am putting a 3sge into an aw10 mr2 - with it the backwall is already depressed back and the front firewall needs a slight dent to accomodate the giant original headers - OR if you feel fancy just make some flat headers..
once again nice work.. and thats the first proper battery install ive seen in a corolla shell, it AE100 EE100 etc requires a DIN styled one
