As with all Group 5 cars (Gr 5 being a silhouette formula), extensive modifications were made to the bodywork. As per the regulations, only the bonnet, roof, doors and rail panel were left unmodified. The rest of the body was re-styled and constructed from lightweight GRIP (glass fibre reinforced plastic). As can be seem from the above two pictures, modifications included wider body sills in front of and behind the door panel and a gently sloping nose beyond the bonnet which encased the double headlamps and square grille. The LB weighed in at 860 kg compared to 1116 kg for the road-going model.
To power the Gr 5 racer, Schnitzer used the Toyota 18R type G engine equipped with a special 16 valve cylinder head which the German company made. The engine was bored out to 2090 cc and a Kugelfischer fuel injection system was installed. In addition to this a KKK Turbo charger was fitted and the combination produced a high performance engine developing an impressive 560 bhp.
