Engineering,
Not Parts Swapping

Silvertune is a 3G Eclipse and 6G7x shop that grew out of a personal build. The AWD Eclipse in the header is mine — it runs 9.1 at 168 on 30-plus psi, and nearly every procedure offered here was worked out on it first.

Why SPE

How It Works

Small operation, deliberately. I would rather do four cars properly than fourteen quickly, and I would rather tell you a part isn't worth buying than sell you one. The Instagram is the portfolio — read a couple of build threads and you'll know exactly what you're getting.

  • 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.

How It Works

From Intake
to Final Pull

01

Consult

Tell me the chassis, the goal and the budget. You get an honest answer on what is realistic before you spend anything.

02

Spec & Quote

An itemized plan — parts, labor, lead time. No surprise line items when you pick the car up.

03

Build

Fabrication and assembly in-house, documented as it goes — the same way the builds get posted.

04

Tune & Validate

Calibration, road verification and a full datalog review. You leave with the logs and the spec sheet.

Appointments welcome — I'd rather walk you through a build in person than describe it over email.
