The Dream

The Heart Transplant

Powerplant: 2.0L Supercharged LSJ EcoTec.

Induction: Eaton M62 Supercharger with 3D-printed intake components.
Target Output: 350-380 HP.
Custom Work: Fabricating custom brackets to adapt the LSJ side-mounts to the Fiero's factory lower engine mount locations.

ECU: MicroSquirt Standalone Engine Management.

Control: Full tunability over ignition timing and fuel maps for the supercharged 2.0L.
Throttle: Likely transitioning to a mechanical cable-driven throttle body for MicroSquirt compatibility.
Integration: Custom-built harness to bridge the LSJ sensors with the Fiero’s factory chassis wiring.
Data: 3D-printed interior pods for real-time monitoring of boost and AFR (Air-Fuel Ratio).

Bushings: Full upgrade to polyurethane bushings throughout the chassis.
Performance: Firmer bushings increase longevity and boost handling by reducing suspension deflection.
Steering: Researching a new rack and pinion solution to replace the factory "slow ratio" steering.
Goal: Eliminating 30+ years of sloppy rubber flex for precise feedback during "Broke Not Broken" road tests.

Phase 1: The Donor Hunt
- Locate 2005-2007 Chevy Cobalt SS or Saturn Ion Red Line donor.
- Verify Eaton M62 Supercharger condition and Laminova intercooler cores.
- Secure the LSJ engine harness (to be modified for MicroSquirt).
- Source a Cable-Driven Throttle Body (e.g., from an early EcoTec or aftermarket) to replace the DBW unit.
Phase 2: Teardown & Prep
- Extract stock 2.8L V6 engine and transmission.
- Degrease and prep the Fiero engine bay for the EcoTec footprint.
- 3D print prototype wire looms and mounting templates on the Kobra S1.
- Torch out 30-year-old rubber bushings in preparation for Polyurethane replacements.
Phase 3: Final Integration
- Install custom mounting brackets (LSJ side mounts to Fiero lower mounts).
- Fabricate/Order custom high-strength CV axles for the increased torque.
- Plumb the front-mounted heat exchanger and pump for the integrated W2A intercooler system.
- Finalize the steering solution to replace the "slow ratio" factory rack.
