Most Wanted JDM Parts Right Now: What Builders Are Buying in 2025

The JDM parts market is hotter than ever in 2025. With classic Japanese cars appreciating in value and a new generation of builders discovering the magic of Japanese performance engineering, demand for authentic JDM components has exploded globally.

At Grovexo, we track what our customers are searching for and buying. Here's exactly what's trending right now.

1. Nissan R34 Skyline GT-R Parts

The R34 GT-R is now legally importable in the US under the 25-year rule, and demand for parts has gone through the roof. Most wanted:

• RB26DETT engine assemblies and cylinder heads
• ATTESA AWD transfer cases and rear differentials
• NISMO and factory aero components
• BNR34 interior trim and instrument clusters
• Brembo brake components (factory fitted)

2. Honda K-Series Swap Components

The K-swap trend continues to accelerate as builders move away from B-series for more modern performance. In demand right now:

• K20A and K20C complete engine assemblies
• K24 long blocks for boosted builds
• Honda Integra DC5 Type R OEM parts
• Civic Type R (EP3/FN2) suspension and braking components

3. Toyota GR86 and AE86 Parts

Both old and new 86s are extremely popular. The new GR86 has generated demand for its FA24 engine components, while the original AE86 remains a collector's favourite with a passionate restoration community.

• 4A-GE 20v Silvertop/Blacktop engines (for AE86 restores and swaps)
• FA24 engine and drivetrain components for GR86/BRZ
• AE86 OEM body panels and interior trim

4. Subaru STI Version 7–10 Parts

The EJ207-powered STI variants remain the go-to platform for AWD performance builds. These cars are now old enough to have parts wearing out — creating high demand for genuine replacements.

• EJ207 short blocks and complete engines
• Subaru STI 6-speed gearbox assemblies
• DCCD limited-slip differentials
• Brembo brake calipers (front 4-pot, rear 2-pot)
• STI suspension struts and springs

5. Mitsubishi Lancer EVO IX Components

The final version of the EVO is considered the peak of the platform's development. Parts are becoming increasingly hard to find through conventional channels — making Japan-sourced components especially valuable.

• 4G63 EVO IX engine assemblies
• EVO IX gearbox and transfer case
• Brembo caliper and rotor sets
• Recaro seat assemblies (factory fitted)
• Body panels — front bumper, bonnet, rear wing

6. Mazda RX-7 FD3S Parts

The twin-turbo 13B-REW engine and the FD3S body are both extremely sought after. Rotary builds are surging in popularity, and genuine FD parts from Japan are significantly better quality than local used options.

• 13B-REW complete engine assemblies
• Sequential twin turbo systems (primary and secondary)
• FD3S OEM body components and power steering racks
