What are the best parts for a Nissan 240SX? It depends on your build goal: for a street-driven KA24 car, the best first upgrades are bolt-ons — a cat-back exhaust and intake. For an SR20DET turbo build, the money goes into engine internals like forged pistons and H-beam connecting rods, plus turbo and fueling upgrades. Shared with the Silvia and 180SX, the S-chassis enjoys one of the deepest aftermarket catalogs of any 90s Japanese platform.
The 240SX — S13 (1989–1994) and S14 (1995–1998) — became the definitive grassroots drift and street car: front-engine, rear-wheel drive, and huge parts interchange with its Japanese-market siblings. This collection spans the full build spectrum: exhaust systems, turbo components, engine internals, engine management, and chassis hardware.
When shopping, pay attention to three things. First, whether a part fits the S13, the S14, or both — some panels and suspension pieces differ. Second, whether it’s built for the KA24 or the SR20 — engine parts are engine-specific. Third, confirm your exact year and trim on the listing before ordering.
This collection pulls from proven S-chassis brands: Megan Racing exhausts, Tomei engine and exhaust components, AEM engine management parts, plus JE Pistons and Eagle connecting rods for engine builds.

Will S13 parts fit my S14 240SX?
Many chassis and drivetrain parts carry over, but body panels and some suspension pieces differ — check each listing for your exact year and model.
How do I know if I have a KA24 or an SR20?
US-market 240SXs came with the KA24E or KA24DE; the SR20DET turbo engine came in Japanese-market Silvias and 180SXs and is a common swap. Buy engine parts for the motor you have.
Do I need a tune for bolt-on exhaust mods?
A cat-back or similar bolt-on typically runs fine on the stock ECU. Once you change the turbo, fueling, or engine management, proper tuning becomes necessary.
Are these parts suitable for drift use?
Many S-chassis parts are developed with motorsport in mind, but always match the part to your power level and driving style.
