3G Eclipse & 6G7x Specialists

Engineered Performance.
Street Proven. Quarter-Mile Validated.

AWD swaps, turbo systems, custom exhaust, standalone setups and ethanol fuel — built around the 3G Eclipse and the 6G7x V6, but not limited to them. Brackets get fabricated, heads get ported and the tune gets written here, proven on my own cars first.

What We Do

One roof, one set of hands on your car from teardown to final pass. AWD swaps, turbo systems, exhaust and standalone tuning are the bread and butter — no sublet fabrication, no mail-order tunes, no "should be close enough."

01

AWD Conversions

Front-drive 3G Eclipse, Galant and Stratus converted to a complete AWD driveline — brackets built from scratch, not bought.

  • Scratch Brackets
  • Subframe Fab

Turbo Systems

Turbo kits built around the chassis, not forced into it. Right-sized selection, boost control that holds, and fuel to match the head work.

  • Manifolds

Standalone & Tuning

Full standalone setups wired to look factory, then calibrated on the road and in the datalogs.

The Build Log

A few of the builds documented on Instagram — the AWD Eclipse, a 6G75 MIVEC Galant, a Stealth 6G72 and the conversion hardware behind them. Every number came off a time slip or a spec sheet. Plenty of customer work never gets posted.

Why SPE

Engineering,
Not Parts Swapping

Silvertune started in a two-bay garage with a laptop, a welder and a stubborn refusal to hand a customer a car we hadn't validated. That hasn't changed — we just have more room and better tooling now.

  • DocumentedEvery build is posted start to finish — teardown, mistakes and all. 413 posts of receipts you can read before you call.
  • Built, Not BoughtTransmission brackets, engine bars and headers get made from scratch. When a part doesn't exist for a 3G, I make it.
  • Proven FirstNew procedures go on my own car for a season before they go on a customer's. The AWD kit was piloted twice before it was offered.
  • Straight AnswersHonest timelines, itemized quotes, and a call before a dollar gets spent that you didn't approve.
