1991-94 S13 (Chuuki S13, S13b)

For 1991, a revised S13 was released in December of 1990. The front bumper was updated to a more agressive, smoother bumper more fitting with the lines of the car - leaving the boxy 80’s syling.

For 1991 the 240SX also received a new set of wheels, a 15" 7 spoke design rather than the “teardrop” wheels of the S13a.

Optional Factory Side Skirt, Front valence, and rear valence were also made avalible as part of a sports package.

Canadian models had Day Time Running lights (DTRL) located underneath the front turn signal indicators. The US version had a grill mesh instead.

The interior fabric was upgradedto a thicker material. Leather was standard with LE models, with suede upholstry on the doors and glovebox.

The newer model also came with redesigned seats - now sporting adjustable headrests.

The steering wheel was changed to true leather as oppose to the hard plastic from the S13a series models.

Availble on the hatchbacks for 1991 was Nissan’s HICAS (click for more info) four wheel steering system. HICAS model S13s had a HICAS warning light on the dash, and decals on the sides of the cars in front of the rear wheels.

2 Projection Map lights were added.

Although priased for it’s exceptional handling, bland reviews resulted from the underpowered KA24E powerplant. Nissan responded in 1991 by upgrading the engine from a Single Over Head Cam (SOHC) setup to a new Dual Over Head Cam (DOHC). The KA24DE was the second generation of the KA series of engine. It’s horse power was stepped up from 140 to 155hp and torque was improved from 152 to 160 ft/lbs.

A factory Viscous Limited Slip Differential (VSLD) system was made available as an option in the US and standard in Canada.

In 1993, a convertable version of the coupe was released.
