About Kits

Kits for Porsche

Design911 offers an extensive selection of package deals for Porsche parts, providing an ideal solution for Porsche enthusiasts looking to upgrade, maintain, or personalise their vehicles. These packages are thoughtfully curated to include complementary components, helping with compatibility and overall cost-effectiveness

A Quick Look at Kits

Kits information on this page is based on details supplied by the manufacturer or distributor, plus any OE references provided with the parts.

Choosing the Right Fit for Your Porsche

Where Kits are listed for Porsche, use the supplied model coverage and OE references to confirm suitability. Check details that commonly affect fitment such as model year, axle or side, and any option codes or connector types where relevant.

  • Typical reasons people choose kits include wanting all the right Porsche parts in one order, reducing the risk of missing seals, clips, or one-time-use fixings, and saving workshop time.
  • Kits help ensure matched components (for example, brake refresh kits, service kits, or suspension refresh kits) so parts work together as intended.
  • Common real-world triggers include repeated failures because a small supporting part was not replaced, mixed part revisions, or mismatched specification between components.
  • If problems occur, they are often traced to incorrect vehicle selection, old core components not addressed, or installation shortcuts rather than the kit itself.
  • Before you start work, compare the kit contents with the Porsche PET diagram and your job list so you know exactly what is included and what may still be needed.
  • Always confirm whether kits are vehicle-specific, and check if bolts, clips, fluids, and other one-time-use hardware are included or need to be added separately.

Browse by Category

If you already know the area you are working on, start with the category and then filter by Porsche model. Where real-world symptoms and typical reasons to replace are provided, use them to keep the wording grounded.

Brakes — Brake components are renewed to restore stopping performance, address wear or upgrade a Porsche for fast road or track use. Common symptoms include vibration under braking, increased stopping distances, squealing, pulling to one side, warning lights and visible wear to discs and pads.

  • Check whether new fitting kits and wear sensors are included or should be added separately.
  • Confirm if parts are OE-equivalent replacements or higher-friction performance upgrades before ordering.

Brake Pads Packages — Brake pad packages group matched front and rear sets, making it easier to renew all pads at once for consistent feel and balance across the axle. Worn pads can cause squealing, low pedal feel, longer stopping distances and may score discs if run down to the backing plates.

  • Verify whether the package covers front, rear, or both axles and whether it is a standard or performance compound.
  • Check the contents list for anti-squeal shims, hardware and any wear sensors you may want to replace at the same time.

Gearbox / Transmission — You change gearbox and transmission parts when you have shifting issues, noise, leaks, or you are refreshing a high-mileage drivetrain. It is also common during clutch upgrades or ratio changes. Typical symptoms include whining in a specific gear, crunching on shifts, or difficulty selecting gears, as well as leaks at seals or casing joints.

  • Not all noise or poor shifting means the gearbox itself is failing—mounts, linkage, clutch, and oil condition can produce similar symptoms.
  • Using the correct-spec gearbox oil and refreshing it is often a sensible first step before major work.

Service Parts — Service parts are replaced as routine maintenance to keep the engine and systems reliable, efficient, and protected. Doing this on schedule reduces wear, helps prevent breakdowns, and maintains performance—especially on older Porsche models where neglected servicing can quickly lead to costly repairs. Symptoms prompting attention include hard starting, rough idle, reduced fuel economy and poor throttle response.

  • Both OEM and reputable aftermarket parts can be suitable—always match the correct specification for your Porsche.
  • Keeping a clear service log helps diagnostics later and can support the car’s resale value.

Service Kits — Service kits bundle the correct parts for a routine Porsche service into one package, reducing ordering mistakes and ensuring you can reset the car to a known maintenance baseline. They are ideal when catching up on overdue work or planning regular servicing to a consistent standard. Symptoms leading to a full kit are often general, such as sluggish running, inconsistent idle, poor economy, or increased engine noise from old oil and filters.

  • Service kits typically include filters and key consumables, but contents vary—check the list carefully and add any extra items you want to replace while access is good.
  • Kits are usually specific to model, year and engine, so confirm these details before ordering.

Exhaust valve guide set. Outlet, 1st Oversize
This is a set of four OE Match exhaust valve guides engineered to replace the worn or original guides in the Porsche 914 air-cooled engine. This is a first-oversize exhaust guide intended to fit cylinder heads that may have experienced wear or require an oversize fit during an engine rebuild. Supplied as a complete set of 4, this kit is ideal for a full cylinder head rebuild or valve job.
SET OF 4

Fits:
Porsche 914-1,7/1,8V
Porsche 914-1,8

Diagram ref no 15

Exhaust valve guides serve several key functions in the overhead valve train:
  Support and align the exhaust valve stems, ensuring they travel straight within the head.
  Maintain correct clearances between the valve stem and guide for proper sealing and combustion efficiency.
  Help transfer heat away from the hot exhaust valve stem into the cylinder head casting.
  Protect valve stems and seats from wear due to excessive lateral movement.

This set of four valve guides ensures that all exhaust valves on the 914’s four-cylinder engine have correct, matched guidance for dependable operation.
This OE Match set matches Porsche factory dimensions and is ideal for full head rebuilds, valve seat replacements or anytime guides show wear.

Function
•  Valve Alignment: Keeps the exhaust valve traveling straight for proper valve seat engagement and sealing.
•  Wear Control: Reduces lateral valve stem movement that would otherwise accelerate wear on the valve and seat.
•  Heat Dissipation: Helps carry heat from the hot exhaust valve stem into the cylinder head.
•  Rebuild Support: Oversize fit for cylinder heads that have been reamed or show wear.

Valve guides wear over time due to high heat, friction, and repeated motion. Worn guides can result in:
  Excessive oil entering the combustion chamber
  Poor compression, rough idle or power loss
  Increased valve stem wear Higher oil consumption and visible exhaust smoke

 Installing a correct OE Match valve guide restores proper valve stem alignment, improves sealing and performance, and supports a longer engine life  especially crucial during a rebuild or head service.

Replace the exhaust valve guide if you notice:
  Blue smoke indicating oil burning
  Low compression in exhaust valve tests
  Rough running or poor idle quality
  Worn valve stems or seats seen during teardown
  During head rebuild or valve seat work

(2) Diagram ref no 1

This kit contains the essential parking brake (handbrake) mechanical components needed to service the rear parking brake system of Porsche 996 models. The set includes:

 2 × OE Match Parking Brake Cables –  Direct-fit replacements for the rear handbrake/parking brake cable on Porsche 996 models, restoring correct cable length, tension, and movement.

 2 × OE Match Guide Tubes – Handbrake cable guide tubes that route the cables correctly through chassis/brake mounts and protect the cable from chafing. They match OE Porsche fitment.

 1 × Brembo Handbrake Shoes – parking brake shoes provide the friction material that presses against the brake drum or parking brake surface to hold the car stationary. Renewing these shoes is critical for restoring proper braking force and safety.

Together, these parts address both the cable drive side and the friction braking side of the parking brake system in one set.

Handbrake cables and guide tubes are exposed to road debris, moisture, and corrosion, which can cause stretching, seizing, or loss of tension. This results in a weak or unreliable parking brake, which may not hold the vehicle safely on inclines or during emergency use. Renewing cables and guides restores precise lever feel and correct mechanical action.

Similarly, parking brake shoes wear down over time and lose friction effectiveness, leading to reduced braking performance and increased stopping distances when using the parking brake. Replacing these with quality Brembo shoes ensures consistent and secure parking brake action, helping maintain vehicle safety and compliance.

Replace this parking brake set if:
•   Parking brake lever requires excessive travel before engagement.
•   The vehicle rolls or creeps when parked on a slope.
•   Handbrake cables show corrosion, fraying, or stiffness.
•   Guide tubes are cracked or worn.
•   Parking brake shoes are thin, glazed, or contaminated with brake fluid.

Exhaust valve guide - 1st oversize - set.
This is a set of six OE Match quality exhaust valve guides designed for the air-cooled Porsche 911 (993) engines produced between 1994 and 1998. These are 1st oversize valve guides, meaning they are slightly larger than standard guides to accommodate engines that have been reamed or show wear in the original guide bores. The set contains six guides, enough for a full cylinder head rebuild on the exhaust side.
SET OF 6

Fits:
Porsche 993 1994 - 1998

Diagram Ref no 2.

Valve guides are precision metal bushings pressed into the cylinder head that support and guide the movement of the exhaust valve stems. Over time, original guides can wear, allowing excessive valve stem play, reducing seal effectiveness, and increasing engine oil consumption. These OE Match valve guides are manufactured to match Porsche’s original specifications, including diameter, material quality and machining tolerance, but in a 1st oversize dimension so they fit reamed cylinder heads.

This SET OF 6 provides a complete set for one engine’s exhaust side - ideal for cylinder-head rebuilds, valve jobs or whenever the exhaust guide bores are undersized due to wear.

The exhaust valve guides:
  Support and align the exhaust valve stems so they travel accurately within the head.
  Maintain correct valve seating and combustion sealing, which is vital for performance and compression.
  Help conduct and dissipate heat from valves into the cylinder head casting.
  Reduce lateral valve stem movement, decreasing wear on stems and valve seats.

By replacing old or worn guides with a matched oversize set, you can restore tight tolerances in the valve train and help ensure efficient combustion and long-term reliability.

Valve guides wear over time due to heat, friction, and repeated valve movement. When guides become worn or oversized gaps develop between the valve stem and guide bore, the following issues can arise:
  Loss of performance and power
  Higher oil consumption
  Reduced sealing and compression
  Increased valve train wear

Installing a correct OE Match valve guide restores correct valve alignment, reduces unwanted movement, supports proper seat sealing, and prolongs the life of your engine’s top end - especially in rebuild or high-mileage applications.

Replace valve guides if you observe:
  Blue smoke from the exhaust (signifying oil burning)
  Rough idle or hesitation
  Poor compression or loss of engine power
  Valve stem play when checked during teardown
  During a cylinder head rebuild or valve job

Fuel pump and fuel sender kit for Porsche 1974-1977 2.7L / 1976-77 3.0 Carrera / 930 1975-1977 3.0L Turbo, combines key fuel delivery and level-sensing components in one package.

What This Product Does
This kit brings together a replacement fuel pump and sender unit to deliver fuel from the tank at the correct pressure while providing a matching level signal to the gauge. It is intended to support reliable running, consistent fuel supply, and accurate tank level indication on Porsche 1974-1977 2.7L / 1976-77 3.0 Carrera / 930 1975-1977 3.0L Turbo


Functions

  • Draws fuel from the tank and feeds it towards the engine
  • Helps maintain appropriate fuel pressure within the system envelope
  • Measures fuel level within the tank for the dashboard gauge
  • Supports smooth starting and running by stabilising fuel delivery
  • Assists in preventing fuel starvation when the tank level is low


Symptoms of Fault

  • Long cranking, intermittent no-start or cutting out under load
  • Hesitation, surging or loss of power at higher revs
  • Whining or humming noises from the pump area
  • Fuel gauge reading erratically, stuck full/empty or inconsistent with actual level
  • Hot-start issues or stalling at junctions


Why Replacement Matters
Age, fuel contamination and electrical wear can cause a pump to become noisy or weak, and sender units can suffer from worn tracks or sticking floats. Replacing tired components helps restore stable fuel flow and more predictable gauge readings, which is particularly relevant on older Porsche 1974-1977 2.7L / 1976-77 3.0 Carrera / 930 1975-1977 3.0L Turbo where many original parts are still in service. Addressing pump and sender issues together can reduce repeat visits into the tank area and supports methodical maintenance on classic 911s.

Fits

  • Porsche 911 1974-1977 2.7L / 1976-77 3.0 Carrera 
  • Porsche 930 1975-1977 3.0L Turbo


FAQs

  • Q: Can a weak fuel pump still allow the car to run?
    A: Yes, a tired pump may run the engine at light load but struggle to maintain pressure during hard acceleration or higher revs, showing up as hesitation or cutting out.
  • Q: Do fuel pump problems always trigger obvious noise?
    A: Not always, but increasing whining or humming from the tank area is a common early sign, especially if performance has started to deteriorate.
  • Q: Could a relay or wiring fault mimic pump failure?
    A: Yes, low voltage, poor earths or a failing relay can cause similar no-start or intermittent running symptoms, so basic electrical checks are sensible before condemning the pump.
  • Q: Why does low fuel level sometimes make symptoms worse?
    A: With little fuel in the tank, the pump can run hotter and may ingest more debris or air, which makes any underlying weakness more noticeable.
  • Q: Should the fuel filter be checked when replacing a pump?
    A: It is common practice to inspect or renew the fuel filter at the same time, as restriction can overload a new pump and affect pressure.
