Important Fitment Information

Engine-bay dimensions and donor-kit tooling vary. Custom engine mounts, transmission crossmembers, oil-pan clearance, firewall clearance, turbo and intake routing, fender-exit openings, exhaust fabrication, cooling connections, driveshaft alignment, and chassis or suspension modifications may be required.

Test-fit the engine, transmission, turbochargers, boost tubes, headers, fender-exit exhaust components, and surrounding chassis parts before cutting, painting, or permanently bonding anything.

Donor model kit, engine mounts, wiring, hoses, oil lines, intercooler and connecting pipes unless shown as supplied components, paint, decals, adhesives, and finishing materials are not included. Some sanding, trimming, drilling, cutting, modification, and test-fitting may be required for best results.
