At JDM Project, we live for these hidden treasures. If you're a true JDM enthusiast, these rare parts might just blow your mind—and your wallet.

🔧 Top Rare JDM Parts That Are Worth Big Money

1. Nismo 400R Engine (RB-X GT2)

Originally built for the ultra-rare Nismo 400R Skyline, this upgraded RB26 variant is the holy grail for GT-R fanatics. If you find one today, expect to pay over $50,000—just for the engine!

2. Mazdaspeed A-Spec Parts for RX-7

Limited aero kits, racing suspensions, and Mazdaspeed seats made for the FD3S are highly collectible. Some genuine kits fetch upwards of $10,000 due to scarcity.

3. TRD Widebody Kit for Toyota Supra (JZA80)

Not to be confused with cheap replicas, the original TRD widebody kits are incredibly rare and often cost more than $20,000 when complete.

4. Mugen NR10 Wheels

Designed by Mugen specifically for racing, these lightweight forged wheels were produced in extremely limited numbers. Today, a mint set can go for $6,000+.

5. Recaro Confetti Seats (JDM Spec)

While Recaro seats are common in the tuning world, JDM-only patterns like the “Confetti” are highly sought-after. A clean pair can easily cost $4,000 or more.

6. Spoon Sports Carbon Fiber Mirrors

Tiny, but valuable. Authentic Spoon mirrors for the Civic EK or Integra DC2 are rare finds. Some clean sets have sold for over $1,200.

7. OEM Nissan Skyline GT-R N1 Headlights

N1-spec headlights for the R32 or R34 are hard to come by and go for ridiculous prices in good condition—$3,000+ per set.

💡 JDM Curiosity:

Some rare JDM parts have appreciated more than gold over the last 10 years. For example, an original TRD kit bought for $5,000 in the early 2000s could now be worth four times that—if it's still in the box.
