Sourcing Hard-to-Find Seals and Gaskets for Nissan Skyline R32 GTRs (And Why Nismo Heritage Is Your New Best Friend)
You have spent years hunting for an OEM rubber seal for your R32 GT-R, scouring forums and messaging sellers halfway across the world, only to discover that the part number has been discontinued—and the tiny piece of rubber you need is now the only thing standing between your engine rebuild and the road.
Here is the thing about the R32 GT-R. It is a legend. But it is also a 30+ year old car with production numbers that were never high—approximately 44,000 units across the entire R32 GT-R run . And when manufacturers stop making parts for a low-volume classic, the original suppliers retire tooling, close operations, or simply move on . The result is a market where a single OEM rubber seal can command multiples of its original price—when it can be found at all . But there is hope. Nissan has recognized the crisis, and through Nismo Heritage Parts, they have begun reproducing exactly the seals and gaskets that restorers need most . This guide walks you through the best sources for R32 GT-R seals and gaskets, from official Nismo reproductions to OEM suppliers and trusted aftermarket alternatives.
TL;DR: The R32 GT-R parts scarcity crisis is real—low production numbers, expired supplier contracts, and decades of hard use have pushed many components into “unobtanium” territory . Nismo Heritage Parts recently added 37 new components to its catalog, including engine seals and gaskets, covering the R32, R33, and R34 . Key sources include: Nengun for OEM parts direct from Japan (full engine gasket kit 10101-05U26 for approximately 38,290 JPY) , NizmoPartsPlug for OEM and Nismo components with U.S. support , and Just Jap for both OEM and Tomei aftermarket gasket sets . For non-OEM alternatives, Stone (Ishino Gasket) supplies the original Nissan factories and offers OEM-equivalent quality . The aftermarket RB26 engine seal and gasket ecosystem is well-developed, with Tomei offering complete metal gasket sets for high-performance builds .
Key Takeaways:
- Nismo Heritage Parts is actively reproducing R32 GT-R components – 37 new parts added recently, including engine seals and gaskets
- Full OEM engine gasket kits are still available – Part number 10101-05U26 ships from Japan via Nengun for approximately 38,290 JPY

The R32 GT-R Parts Crisis: Why Seals Are So Hard to Find
Let me start with the uncomfortable truth that every R32 owner eventually faces. The car is old. Really old. The R32 GT-R was produced from 1989 to 1994—more than 30 years ago . And the parts supply situation has become a genuine crisis.
Did you know? Nissan only made roughly 44,000 R32 GT-Rs across the entire production run . That is not many cars. When manufacturers stop supporting a model (usually 10-15 years after production ends), the economics work against continued parts availability . Tooling costs for low-volume specialty parts are high, and the addressable market is small.
Here is where things get really interesting. The R32 GT-R’s parts scarcity problem has several compounding causes :
- Low original production numbers – 44,000 units is tiny compared to mass-market cars
- Suppliers retired tooling – Original manufacturers moved on decades ago
- The 25-year import rule – When R32s became legal in the US around 2015, demand spiked without a corresponding increase in parts availability
One forum member describes discovering perished rubber plugs in the floor of his R32 GT-R when removing old sound deadening. “Most were either somewhat perished, had shrunk or were destroyed” . This is the reality of owning a 30-year-old car—rubber seals degrade regardless of mileage.
Bold safety reminder: Do not ignore dried-out seals. A leaking camshaft seal or valve cover gasket on an RB26DETT can spray oil onto hot turbochargers, creating a fire hazard. In a high-performance engine like the GT-R’s, seal integrity is not optional.
Nismo Heritage Parts: The Factory Rescue Operation
Now, here is the best news for R32 owners. Nissan’s performance division, Nismo, has launched a Heritage Parts program specifically to address the parts crisis.
According to Nismo’s recent announcement, the program is “about as close to a factory rescue operation as the GT-R community is likely to see” .
What was just added: Nismo recently added 37 new components to its Heritage catalog, covering the R32, R33, and R34 GT-Rs .
What categories are covered: The expansion spans multiple categories—”engine seals and gaskets, fuel injectors, chassis hardware, interior trim pieces, and engine bay components” .
Why this matters: “These are exactly the categories that cause the most headaches for restorers because rubber seals degrade with age regardless of mileage, OEM gaskets are often required for proper fitment when rebuilding the RB26DETT, and interior trim for a 30-year-old Japanese domestic market car is nearly impossible to source” .
One specific example: Nismo now reproduces the headlamp hole seal (Part #62569-RHR20) for late-production BNR32 models (from August 1991 onward, excluding N1 specifications). This seal fills the gap between the headlamp assembly and the body, preventing water, dust, and debris from entering the engine compartment .
For owners who have spent years hunting discontinued OEM parts through “grey-market channels, specialist brokers, and dwindling new-old-stock supplies,” this expansion is a lifeline .
Did you know? The R32 GT-R’s production was so long ago that even well-preserved examples are now fighting “component attrition”—the gradual failure of rubber and plastic parts simply due to age .
OEM Sources: Where to Buy Genuine Nissan Seals and Gaskets
If Nismo Heritage does not yet have the specific seal you need, several trusted suppliers can source genuine OEM Nissan parts directly from Japan.
Nengun Performance (Japan Direct)
Nengun is a well-established JDM parts supplier that ships genuine OEM Nissan parts worldwide directly from Japan.
Full engine gasket kit: Nengun offers the complete Nissan OEM engine gasket kit, part number 10101-05U26, for the RB26DETT .
Price: Approximately 38,290 JPY (Japanese Yen) .
Fitment: This kit fits multiple R32 GT-R production years, including 1990, 1991, 1992, and 1993 models, as well as V-Spec variants .
How to use: Search Nengun’s website by OEM part number to verify availability for your specific seal or gasket.
NizmoPartsPlug (US-Based Sourcing)
For North American buyers, NizmoPartsPlug offers a valuable service. According to their website, “We specialize in OEM Nissan and JDM components and have access to an extensive supplier network” .
What they offer: OEM direct-fit parts, including front differential input flange seals for R32-34 GT-R models .
Sourcing service: “If you don’t see the part you need listed on our site, reach out to us at Nizmopartsplug@gmail.com or call us with the part number and we’ll do our best to source it for you” .
Note on special orders: “Please note that special order parts may require a deposit and are non-returnable once ordered” .
Just Jap (Australia)
Just Jap is another established source for OEM Nissan gaskets and seals. They list genuine Nissan head gaskets for the RB26DETT as well as various seals and grommets .
What they carry: Genuine Nissan head gaskets (fitting R32/R33/R34 GT-R and Stagea 260RS), turbo manifold gaskets, and crank angle sensor grommets for RB-series engines .
Best for: Australian and Asia-Pacific buyers, though they ship internationally.
Bold safety reminder: When ordering OEM parts, always verify the part number against Nissan’s EPC (Electronic Parts Catalog). A single digit off can mean ordering the wrong gasket. Nengun’s listings include detailed production date and vehicle specification information to help you confirm fitment .
OEM Equivalent: Stone Gaskets (The Factory Supplier)
Here is a secret that many R32 owners do not know. The company that made the original gaskets for Nissan is still in business, and they sell under their own brand.
Stone is a Japanese gasket manufacturer owned by Ishino Gasket Mfg. Co., Ltd. According to the company’s history, “The brand Stone came to market in 1933, when the company entered into an agreement with Ishino concern Nissan to supply gaskets and seals” .
Who they supply: Stone gaskets are supplied to Nissan Motor Co., Honda Motor Co., Suzuki Motor Corporation, Toyota Motor Corporation, and Yamaha Motor Co. .
Quality: “Stone products are popular not only in Japan and Asia but also around the world” . Because they supplied the original Nissan factories, Stone gaskets are functionally identical to OEM—often at lower prices.
Finding Stone parts: Search for “Stone RB26” or “Ishino Gasket” on JDM parts websites. These are often stocked as OEM alternatives without the Nissan branding markup.
Did you know? In 2003, Ishino Gasket joined the NOK group of companies, further expanding their manufacturing capabilities .
Aftermarket Performance Options: Tomei
If you are building a high-performance RB26DETT rather than a concours restoration, aftermarket gaskets from Tomei are an excellent choice.
Tomei Combination Metal Engine Gasket Set – According to Just Jap’s product listing, the Tomei set includes :
- Tomei Head Gasket (87mm Bore, 1.2mm thickness)
- Tomei Intake Manifold Gaskets
- Tomei Exhaust Manifold Gaskets
Fitment: Fits R32, R33, R34 Skyline GT-R (RB26DETT) and C34 Stagea 260RS .
Why choose Tomei: Multi-layer metal (MLS) gaskets are superior to OEM composite gaskets for high-boost applications. They withstand higher cylinder pressures and are less likely to fail under track conditions.
When to use OEM instead: If you are restoring to factory specification or your engine is stock, OEM gaskets from Nissan or Stone are appropriate. For built motors with forged internals and increased boost, Tomei’s metal gaskets are the better choice.
The Sealant Question: What to Use When No Gasket Exists
Some seals on the R32 GT-R are not available as replacement parts—especially body seals and grommets that were never designed to be serviced separately.
Forum members on SAU Community have discussed this exact problem: “I stripped out all of the old sound deadening material from my R32 GT-R… the rubber grommets / plugs / covers in the floor were removed. Most were either somewhat perished, had shrunk or were destroyed” .
What the forum recommends:
One member suggested using “a little bit of non-acid silicone, or a PU type body sealer from 3M or Sika” .
Another recommended “SIKAFLEX 221 black sealant” .
Guidance on which seals to seal: “Use that simple logic, only seal those you will never need to remove. I don’t seal the boot plugs” . Some floor plugs are designed to allow drainage or access to bolts that require future maintenance—do not seal those.
Bold safety reminder: Do not use standard silicone bathroom caulk on your GT-R. Use automotive-grade products specifically formulated for exposure to oil, heat, and vibration. The wrong sealant can deteriorate and leak, or worse, damage paint.
