If you've spent any time in Porsche enthusiast circles, you've heard the term "unobtanium parts." It's a joking but accurate label for components that are nearly impossible to find—either because they were produced in tiny numbers, were never officially sold in certain markets, or have simply vanished from the supply chain over the decades. For owners restoring a 356, an early 911, or a limited-edition model like the 959, sourcing these parts can be the most frustrating part of the project. This guide explains what makes a Porsche part unobtanium, why they're so elusive, and practical ways to track them down without wasting time or money.
What Are Unobtanium Porsche Parts?
Unobtanium parts are components that are no longer manufactured, have no direct replacement from Porsche or OEM suppliers, and are extremely scarce in the used market. The term originated in aerospace and engineering circles, but car enthusiasts adopted it decades ago. For Porsche, some parts become unobtanium due to limited production runs, model-specific features, or because they were only used for a single year.
The Origins of the Term
While the exact origin is debated, "unobtanium" started as a humorous way to describe materials or parts that were theoretically possible but practically unavailable. In the automotive world, it became shorthand for "if you have to ask, you can't get it." It's not an official Porsche term, but you'll hear it at every PCA event.
Real-World Examples
- 1973 911 RS 2.7L ducktail spoiler – Original fiberglass units are incredibly rare, and even reproductions vary in quality.
- 356 Carrera GS engine parts – The four-cam engine used unique camshafts, rockers, and other components that are almost impossible to find.
- Porsche 918 Spyder production parts – Some body panels and interior trim pieces were never made in excess, so any replacement after a crash can take months.
- Early 911 (1965–1973) window regulators and door handles – Many of these are NLA (no longer available) from Porsche, and used ones are brittle.
- 914/6 fuel injection components – Only a few thousand 914/6s were built, so parts like the intake runners and throttle bodies are highly sought after.
Why Are These Parts So Hard to Find?
Several factors contribute to a part achieving unobtanium status.
Limited Production and Low Volume
Porsche has a long history of building small batches of special models. The 911 GT1 Straßenversion, the 964 Turbo S, and the 993 GT2 all had tiny production runs. Even mainstream models like the 912 or 924 had lower volumes than mass-market cars, so replacement parts were never manufactured in large quantities.
Discontinuation by Porsche
Over time, Porsche phases out support for older models. The official parts catalog shrinks, and once stocks of genuine parts are depleted, they're gone forever. Some parts may still be listed as NLA (no longer available) if Porsche decides not to reproduce them.
Niche Demand and No Economies of Scale
If only a few hundred owners need a specific part, no manufacturer will invest in tooling to reproduce it. Small-batch reproduction is possible, but it's expensive and not always done well.
How to Source Unobtanium Porsche Parts
Finding these parts requires strategy, patience, and a willingness to network. Here are the most effective methods.
Online Communities and Forums
- Pelican Parts Forum – The 911 and 914 sections have active classifieds and knowledgeable members.
- Rennlist – The largest independent Porsche forum with dedicated marketplace sections for parts and cars.
- Porsche Club of America (PCA) – Regional newsletters and the national magazine often have classified ads.
- Facebook Groups – Many niche groups exist, like "Porsche 356 Parts" or "Porsche 911 Early Parts."
Post a polite "want to buy" ad, and be specific about what you need, including part numbers if you have them. Experienced collectors often hoard parts and might be willing to sell.
Specialty Suppliers and Wrecking Yards
- Getty Image (no relation) – A well-known dismantler of vintage Porsches in California.
- Parts Heaven – Offers used parts for air-cooled Porsches and has an extensive inventory.
- EASY (European Auto Salvage Yard) – Based in Pennsylvania, specializes in German cars.
- Stoddard – Has been supplying Porsche parts for decades and carries some NOS (new old stock) items.
- RP Porsches – A UK-based breaker that ships internationally.
Call or email first; many don't list all inventory online.
Reproductions and Aftermarket Alternatives
When genuine parts are impossible to find, consider high-quality reproductions. Some vendors specialize in remanufacturing unobtanium parts:
- Trevor Booth (Restoration Design) – Makes many early 911 and 356 body panels.
- Sierra Madre Collection – Reproduces trim, emblems, and interior pieces for 356 and 911.
- CSP (Classic Sportparts) – Known for faithful reproductions of 911 parts, especially suspension and engine components.
- Elephant Racing – Offers polyurethane bushings and suspension upgrades that replace worn-out rubber parts.
Be cautious: some reproductions are poor fits. Read forum reviews before buying.
Save a Search on Auction Sites
While this guide doesn't focus on marketplaces, you can set up saved searches for specific part numbers on hobbyist-friendly auction sites like Bring a Trailer (but avoid mentioning Amazon). Check sold listings to understand fair prices.
Tips for Buying Rare Porsche Parts
- Verify Authenticity – Many fakes exist. Ask for clear photos, part numbers, and original packaging if possible. A genuine part often has casting marks or stickers that are hard to replicate.
- Compare Condition – A part that looks rusty or broken may not be salvageable. Factor in restoration costs.
- Set a Budget – Unobtanium parts can cost thousands. Decide what you're willing to pay before you start hunting, and stick to it. Sometimes a reproduction is a smarter choice.
- Network – Attend Porsche swap meets, PCA events, and concours. Face-to-face conversations often lead to leads.
- Be Patient – It's not uncommon to search for a part for months or even years. Don't rush into a bad purchase.
Final Recommendation
Chasing unobtanium Porsche parts can be a rewarding part of the restoration hobby, but it requires a realistic mindset. Focus on joining dedicated forums and specialty suppliers first, and be prepared to pay a premium for true NOS or pristine used parts. If a part is truly unavailable, don't despair—quality reproductions are getting better all the time. The key is to enjoy the journey, celebrate small victories, and never stop asking around. With persistence, you'll find what you need, or at least a workable alternative that keeps your Porsche on the road.
