When it comes to building a Porsche 911 restomod or backdate, the choice of platform is everything. At Shoreline 911, we specialize in transforming both the Porsche 964 and Porsche 993 into timeless, driver-focused machines. But which platform is better for your build?

Both are iconic. Both are air-cooled. And both are built for transformation. But they offer different strengths depending on what you value most in a classic Porsche.

The Case for the Porsche 964

The Porsche 964, produced between 1989 and 1994, is often considered the sweet spot between classic feel and modern usability. It introduced innovations like ABS, power steering, and a revised suspension, while keeping much of the raw, mechanical edge of earlier 911s.

For those seeking a truly analog driving experience with just enough comfort for daily use, the 964 is a favorite. Its compatibility with wide-arch conversions, long-hood styling, and vintage trim makes it an ideal candidate for 911 backdate builds. Whether you're imagining a 911 outlaw build or a subtle tribute to the G-series 911, the 964 chassis handles it all with authenticity.

The Case for the Porsche 993

The Porsche 993, built from 1994 to 1998, represents the final chapter of the air-cooled 911. It featured a more refined multi-link rear suspension, better aerodynamics, and improved drivetrain reliability. For many enthusiasts, it’s the most complete air-cooled 911 ever made.

As a base for a Porsche restomod, the 993 shines with its structural rigidity and smoother handling characteristics. It’s the perfect platform for clients seeking modern performance without giving up the classic feel. And for those who love subtle updates, the 993 can be transformed into a truly bespoke, reimagined 911 — one that blends timeless aesthetics with long-distance comfort.

Performance Potential

Whether you choose a 964 or 993, Shoreline 911 offers the same powertrain options across both. Our 3.6L air-cooled flat-six with individual throttle bodies delivers 330 BHP, while the 3.8L variant reaches 340 BHP. For clients seeking maximum output, our 3.6L supercharged configuration produces up to 410 BHP — making it ideal for performance-focused restomod Porsche builds.

Each car is available in Carrera 2 (rear-wheel drive) or Carrera 4 (all-wheel drive), giving you full control over traction, weight distribution, and road feel.

Visual Transformation and Bodywork

Backdating a 964 or 993 involves reshaping the body to resemble early long-hood 911s from the late ‘60s and early ‘70s. We sculpt new bumpers, widen the arches, refine the roofline, and apply era-correct details like chrome trim or central fuel fillers. Both the 964 and 993 can be seamlessly adapted to a classic 911 backdate look — the choice comes down to whether you prefer a rawer starting point or a more refined canvas.

Interior Refinement

The cockpit of every Shoreline 911 build is custom-finished and stripped of anything unnecessary. From body-coloured interior tubs to period-correct gauges, clean leather dashboards, and minimal distractions, each interior reflects the vision of its owner. Both the 964 and 993 cabins can support modern upgrades like Porsche PCCM, Apple CarPlay, and navigation — all hidden within a classically styled layout.

So, Which Should You Choose?

If you’re after the most authentic vintage experience — with raw steering feel, simplified systems, and a more mechanical connection — the 964 is your platform.

If you want a bit more refinement, smoother road manners, and enhanced engineering without losing the air-cooled soul, the 993 is the one.

Both are incredible foundations for a restomod Porsche 911, and both are available through Shoreline 911 with bespoke build slots.
