PRODUCT DETAILS ▾
RallySport Direct proudly carries a great selection of quality upgrades and accessories brought to you by GrimmSpeed.
This is the GrimmSpeed Turbocharger Coolant Line Kit. This coolant line kit has been designed to be a direct replacement for the GrimmSpeed JB400 or BB500 turbocharger. These lines feature stainless steel construction and are zinc coated for extra protection against corrosion. The GrimmSpeed turbochargers utilize a cross-flow cooling layout rather than the factory design with the inlet and outlet on the same side of the center housing rotating assembly (CHRA). These cooling lines will line up with the factory feed and return soft lines to make the installation straightforward.
SPECS:
- Stainless steel construction
- Zinc plated
- Direct replacement coolant lines for the GrimmSpeed EJ-series turbochargers
- Will connect to the OEM rubber coolant feed/return lines for a simple installation
- Compatible with all USDM turbo EJ20 and EJ25 engines
- Will include replacement copper washers and banjo bolts
WHY WE CARRY THIS ▾
We only list parts we’d run ourselves or recommend to a friend building a real car. If it feels vague, unverified, or inconsistent, it doesn’t make the cut.
- Fitment-first mindset — no “universal” roulette
- Brand reputation matters — we favor proven manufacturing
- Support that actually responds with real answers
WHAT TO EXPECT ▾
This is the clean path: correct fitment, clean install, and results that match the intent.
- Install-ready experience with correct mounting where provided
- Finish that holds up to real driving, not just photos
- Selections on this page drive the exact fitment shipped
TRUST, BUILT INTO THE PROCESS.
Anyone can list parts. We curate what belongs on a serious build. Our goal is simple: fewer surprises, cleaner installs, and confidence when you hit “Buy.”
Fitment checked
We prioritize vehicle-specific listings and clear selection logic so you’re not gambling on compatibility.
Brand discipline
Proven manufacturing and consistent quality matter more than hype. We bias toward what actually holds up.
Real support
If you have a question, you’ll get a human answer that helps you finish the build — not a copy-paste shrug.
