Why choose Scooby Upgrades, by EKS JDM?

Superior Parts + Years of Tuning  Knowledge + Real Support + Real Workshop

Scooby Upgrades brings together performance Subaru parts, quality used components, bespoke engineering and the hands-on workshop experience of EKS JDM.

Whether you are maintaining, repairing or upgrading your car, our team can help you find the right parts and the best way forward, whether it be an economical build, or pampering a garage queen.

  • How the site will evolve: Summer 2026, will see ‘the basics’ go live. This will then be followed by an integration with our eBay / Subaru Breakers (for used parts). After this, more fine-tuned packages will evolve, for each Subaru platform, for DIY Servicing and Tuning. 
  • DIY & professional support: From DIY servicing and home engine builds to full workshop projects, we can advise on fitment, supporting parts and next steps.
  • More than an online catalogue: Call or email us for performance parts, used components, bespoke solutions, diagnostics, servicing, tuning and health checks that may not yet be listed online.

Please note, it may take months, or even years, for ALL of our bespoke engineering services to be put onto the website, so please, if in doubt, call or email, so we can get your project off the ground sooner rather than later!
