S14 vs S15 — Drift Build Comparison (2026)

You can spot S14 vs S15 owners by the argument they’re willing to have at 2 a.m. Both share the same SR20DET-era Nissan DNA, both drift beautifully, but the build paths diverge sharply once you start writing checks.

Specs at a glance

• S14 (1995–1998): 2.0L SR20DET (Kouki) or KA24DE (US-spec), 5-speed manual, 2,800 lb, US-legal everywhere
• S15 (1999–2002): 2.0L SR20DET (factory turbo, helical LSD, 6-speed), 2,900 lb, only US-legal as 25-year imports starting 2024

Acquisition cost

A clean US-market S14 in 2026 trades for $7,000–$11,000. A US-imported S15 (now legal under the 25-year rule for 1999 cars) starts at $25,000 and goes up fast for clean Spec-R examples. The cost gap is roughly 3×.

Parts availability

S14: deepest aftermarket of any drift chassis. Every body panel, suspension arm, mount, and bracket is reproduced. S15: 80% parts shared with S14 (suspension geometry is the same), but interior trim, factory aero, and Spec-R-specific items have to come from Japan.

Engine bay

The S14 ships with KA24DE (2.4L NA inline-four) in the US — most builds either turbo the KA, swap an SR20DET, or go LS. The S15 came factory with SR20DET — saves you the swap budget. Both engine bays accept 1JZ, 2JZ, RB25, RB26, and LS swaps with documented kits.

The verdict

If your goal is "drift a Silvia," buy an S14 and swap whatever motor you want. The 3× cost difference buys a full build instead of a clean title. If your goal is "own an S15," save up — the chassis is worth what people pay for it, and JDM imports only get rarer.
