The S14 sits between the S13 and the highly sought-after S15 in Nissan’s legendary S-chassis lineup. While the S13 established the platform’s reputation for perfect weight distribution and remains one of the best-ever drift cars, the S14 slightly altered the formula, featuring a wider stance and longer wheelbase, which many fans prefer.
For USDM owners stuck with the underwhelming KA24DE “truck engine,” don’t panic – you’ve got options, too! The heavyweight iron-block KA24DE can actually handle some respectable boost with the right supporting modifications, believe it or not.
Our KA24DE turbo kit guide covers everything from budget-friendly setups to premium twin-turbo kits, capable of transforming the typically underpowered KA into a 400+ horsepower tire-shredder.
Those looking for maximum power potential might want to consider going for an LS swap right away. While it’ll undoubtedly make the JDM purists shed a tear, the lightweight design and 400 horsepower potential of the LS, with minimal modifications, make it an ideal option that’s well-supported with off-the-shelf parts. You could also keep things JDM with an RB26DETT, or a 1JZ (or 2JZ) swap!
Of course, the SR20DET remains the favorite among loyal S-chassis enthusiasts. Our SR20 tuning guide breaks down the essential mods to maximize the JDM engine’s potential, from intake and exhaust upgrades to turbo selection.
Regardless of which engine path you choose, don’t forget to upgrade the handling! We explore the vast range of coilover options, from budget-friendly ISR setups to premium KW Variant 3s, which transform the S14’s already impressive cornering (and sideways) abilities.
With clean stock 240SXs now fetching (wait for it…) over $30,000 (a 2025 auction saw a 119k-mile example sell for $31,000!), these cars are becoming real investments. Given these crazy prices, you might even be able to import a JDM S15 for similar money!
We’ll help you make the most of what the S-chassis has to offer, whether you’re preserving a clean example or building your dream drift project.
