LS Coil Conversion Bracket Plans for the 1.8L Ecotec

Chevy Cruze LS Coil Conversion Bracket Plans for 1.8L Ecotec – DXF, AI, Wiring, and Full Assembly Guide

If you’re building power with a 1.8L Ecotec or 1.6L Turbo Ecotec, your ignition system can either be your weak link—or your hidden weapon. This Chevy Cruze LS Coil Conversion Bracket Plan is the exact system I used on my 525 WHP Chevrolet Cruze, and it’s held up to boost, abuse, and street miles without missing a beat.

With this kit, you can cleanly install high-performance GM LS coils directly onto your Ecotec valve cover using brackets you cut yourself—or have laser-cut using the provided DXF and AI files. But this isn’t just a bracket kit anymore…

I’ve included everything you need to knock this out with confidence, even if it’s your first time.

What’s Included:

✅ DXF & AI cut files for LS coil bracket and cam cover adapter
✅ Full step-by-step install video with placement guide
✅ Complete wiring diagram for proper coil connections
✅ Parts list with recommended coils, bolts, spacers, and connectors
✅ Hardware & tools checklist for easy sourcing
✅ My trusted vendor list for laser cutting services
✅ Tuning info and ready-to-drop HPTuners parameters for LS coil support

Whether you’re running a budget turbo build or crafting a full-blown street monster, this kit eliminates spark blowout and coil cut under load. You’ll gain better reliability, stronger ignition, and cleaner tuning potential—all in one package.

No guesswork. Just a proven ignition upgrade that bolts in, wires up, and fires hard.
