Description

Bring your 964 back to “Zero-Mile” perfection. At Emegatronic, we don’t just repair engines; we perform a comprehensive mechanical restoration. The M64 flat-six is an engineering masterpiece, but after decades of heat cycles and mileage, even the finest Porsche engines require expert intervention. Our top-tier rebuild service returns your 964 to factory-plus specifications, ensuring modern reliability without losing the soul of the air-cooled experience.

The Emegatronic Process: Precision Without Compromise

1. Full Teardown & Forensic Inspection Every engine is stripped down to the crankshaft. Components are subjected to hot-tank cleaning and vapor blasting to remove decades of carbon and sludge, followed by a meticulous inspection for tolerances, cracks, and wear.

2. Machining & Internal Upgrades * Crankshaft & Case: Crankshafts are magnafluxed and polished; cases are checked for alignment and “flowed” to ensure optimal oil pressure and longevity,balanced to within 0.1 grams.

    2,1. Cylinder Head & Valvetrain (The Breathing)

                    The 964 heads are prone to guide wear and thermal fatigue. We solve this by modernizing the materials.

• • Valve Guides: Replacement of factory guides with Phosphor Bronze equivalents for superior heat dissipation and reduced friction.

  • Valve Seats: Three-angle performance valve job to optimize flow at low-to-mid lift.

  • Sealing Surface: Heads are precision-milled to ensure a perfect 100% flat mating surface with the cylinders, eliminating the 964’s historic “weeping” issues.

  • Springs & Retainers: New OEM or high-rate Titanium retainers (optional) to prevent valve float near the 6,800 RPM redline.

• The “Dilavar” Solution: We replace aged head studs with high-strength or performance RS studs to prevent the dreaded snapping and head-leak issues common in this generation.

3. Premium Component Integration We use only OEM or superior-grade performance parts:

• New Internals: New main and rod bearings, timing chains, guide rails, and tensioners.

• Sealing: A complete gasket and seal overhaul from top to bottom, including upgraded viton seals to ensure a bone-dry garage floor.

• Performance Options: Custom configurations available, including  Mahle forged pistons, 3.8L 4.0 L conversions, and performance camshaft or GT3 Crankshaft for 4.0 conversions .

4. Aesthetic Restoration A world-class engine should look as good as it runs. Our rebuilds Optional:

• Powder-coated fan and valve covers in OE or custom finishes.
• Re-plated hardware and chromated fan housings.
• Vapor-blasted aluminum surfaces for a “fresh-from-Stuttgart” appearance.
