フィーチャー ビルド
PROJECT HACHIROKU
What started as a rusty shell became our calling card. A balanced, naturally-aspirated screamer built to dance through the hills — proof that a JD Garage build is about feel, not just figures. Every weld, every shim, every alignment pass was done in-house. This is the standard every car on our ramp is held to.
- Forged internals
- Standalone ECU
- Coilover + LSD
- Corner-balanced

WHY JD GARAGE
We treat your car like it's parked in our own garage — because half of these builds started exactly that way.
Dyno, Not Guesswork
Every tune is verified on our in-house dyno. You leave with a printout and numbers you can trust.
Straight Talk
Honest quotes, no mystery labour, no parts you didn't ask for. We tell you what it needs — and what it doesn't.
Builders, Not Fitters
Two decades deep in JDM platforms. We don't just bolt parts on — we make them work together.
