For the front swap, match the Z32 caliper to rotor thickness and use conversion brake lines. The cited guide identifies 26 mm aluminum calipers as 1990 non-turbo only; 30 mm aluminum calipers as 1990 twin-turbo and all 1991 through mid-1992.5; and 30 mm iron calipers as mid-1992.5 through 1996. The Z32 front brake swap itself does not require an S14 upright or S14 ball joint; those parts are required only when an S13 owner chooses an OEM S14 front 5-lug conversion. For a full rear conversion, the guide specifies non-turbo Z32 parking-brake/backing hardware and non-turbo Z32 or S14 hubs when converting to 5-lug. Handle S13/S14 parking-brake cable routing through SCH-0018.

Fitment
For the front swap, match the Z32 caliper to rotor thickness and use conversion brake lines. The cited guide identifies 26 mm aluminum calipers as 1990 non-turbo only; 30 mm aluminum calipers as 1990 twin-turbo and all 1991 through mid-1992.5; and 30 mm iron calipers as mid-1992.5 through 1996. The Z32 front brake swap itself does not require an S14 upright or S14 ball joint; those parts are required only when an S13 owner chooses an OEM S14 front 5-lug conversion. For a full rear conversion, the guide specifies non-turbo Z32 parking-brake/backing hardware and non-turbo Z32 or S14 hubs when converting to 5-lug. Handle S13/S14 parking-brake cable routing through SCH-0018.
Aftermarket options
Checked 240SXMotoring package at $394.99 combines conversion lines, P2M rotors, and selected Hawk pads and says it usually ships the same business day. Calipers are explicitly not included. Rear conversion additionally needs drum parking-brake hardware and the SCH-0018 cable path. Centric 130.42603 is a verified early-Z32 1-1/16-inch three-port reference but the checked seller marked it discontinued and out of stock.
Before you buy
Match 26 mm or 30 mm calipers to rotor thickness. The checked package excludes calipers and rear parking-brake hardware. Used-caliper inventory is unreplenished and selection-specific. Front brake conversion does not itself require S14 uprights/ball joints. Centric 130.42603 was discontinued/out of stock at the checked seller.
