DESCRIPTION:
When your turbo fails, you face a choice.
Do you replace it with the same stock turbo and get the same stock performance?
Or do you upgrade to something better?

INTRODUCING THE TURBO MANIFOLD KIT DIESEL MECHANICS ARE GOING CRAZY ABOUT:
This is the answer to the turbo replacement question. This is the upgrade path that makes sense.

THE SITUATION:
Your X15 or ISX15 turbo is failing or has failed. You need a replacement. But why settle for stock when you can upgrade to better performance, better reliability, and better efficiency?

THE SOLUTION:
The HE400VG Turbo & Manifold Replacement Package — the turbo upgrade that keeps everything you love about your engine while giving you everything you want.

WHAT YOU GET:
TURBO:
✓ Upgraded 70-millimeter compressor wheel (bigger than stock)
✓ Direct stock replacement (bolt-on upgrade)
✓ Better horsepower
✓ Lower EGTs
✓ Better fuel mileage
✓ No programming required
✓ No tuning needed
✓ No deletion required
✓ Keeps your VGT (smooth spool-up)
✓ Keeps your Jake brake (third stage retained)

MANIFOLD:

Prone to leaking issues
A frustration point during replacement
