Porsche Boxster IMS Bearing Replacement Dubai
Plan a compatible IMS bearing replacement before failure damages your engine. We explain the bearing options, check whether your engine suits the work and quote the fitted total. Allow an estimated AED 8,000–15,000 including VAT for a suitable external retrofit.
IMS replacement cost in Dubai
For an eligible, healthy engine with an externally replaceable bearing, budget AED 8,000–15,000 including 5% VAT. This is a planning estimate informed by published replacement costs, not a confirmed PorscheGarage tariff or a fixed package.
| Work | Price basis | What to expect |
|---|---|---|
| External bearing retrofit | AED 8,000–15,000 Guide total with VAT | Compatible replacement kit, normal gearbox removal and refitting, installation hardware and seals required by the kit, oil and filter, and final checks. |
| Pressure-fed plain-bearing conversion | Vehicle-specific quotation | Confirm the complete conversion kit, oil-feed arrangement and additional fitting work. It can exceed the retrofit budget. |
| Large internal bearing or existing engine damage | Engine-work quotation | Engine removal, strip-down and any rebuild are separate work. The external-retrofit estimate does not cover them. |
Included and additional work
The initial fault check is free. Detailed engine qualification, sump removal, borescope or compression testing are quoted separately when required. A clutch, flywheel, rear main seal, timing repairs, seized fasteners or contamination clean-up are extra unless listed in your quotation.
Allow time for a careful job
Plan around 2–3 working days for an uncomplicated external replacement after the kit is available and the engine is accepted for the work. This is an estimate, not a guaranteed collection date. Parts ordering, additional testing or repairs can extend it.
Your engine version, gearbox, installed bearing, chosen kit and any previous engine replacement affect the total. Send the model year and available service history for a quote showing parts, labour and VAT together.
Which Boxsters need this work?
The intermediate shaft, or IMS, helps drive the camshafts in earlier M96 and M97 engines. Its bearing design determines whether replacement is possible with the engine assembled.
- 1997–1999
- Original engines generally use an externally serviceable dual-row bearing.
- 2000–2004
- 2000–2001 are crossover years for dual- and single-row bearings. Later 986 engines generally use the smaller single-row version. Identify the installed bearing before ordering.
- 2005
- Early 987 engines can have a serviceable bearing; some later builds have the larger internal version. The model year alone cannot settle this.
- 2006–2008
- The original larger bearing normally requires engine disassembly for replacement. Removing its outer seal is a separate specialist maintenance decision, not a bearing replacement.
- 2009 onward
- The later engine family eliminated this intermediate shaft. Factory-standard 987.2, 981 and 718 Boxsters do not need this M96/M97 IMS retrofit.
A replacement engine can change the answer, even in an earlier car. The VIN, engine identification, invoices and physical bearing arrangement matter more than registration year alone.
Retrofit or pressure-fed conversion?
Compare the specific kit, its installation requirements and future maintenance. “Upgraded IMS” does not identify the design or its service interval.
A serviceable replacement
Ceramic-hybrid ball-bearing kits and suitable cylindrical-roller kits replace the original bearing in compatible engines. LN Engineering’s IMS Retrofit products and RND roller products are distinct options; the selected part number should appear on the quote.
These remain wear components. Ask for the kit maker’s current time and mileage replacement limits and retain the installation record. A longer interval is not a promise that the whole engine cannot fail.
A different bearing design
The IMS Solution replaces the rolling-element arrangement with a pressure-fed plain bearing in eligible applications. It requires the complete compatible kit and oil-feed installation.
It is intended to remove periodic rolling-bearing replacement from this part of the engine. Oil servicing and the rest of the engine’s maintenance still matter. We confirm suitability, supply and fitting cost before offering this option for your car.
A new bearing cannot rescue an engine already contaminated by a bearing failure. Kit choice follows engine suitability, not a claim that the most expensive part can overcome existing damage.
Combine it with clutch work
On a manual Boxster, clutch replacement already involves access that overlaps with an external IMS job. Quoting the work together can reduce duplicated removal and refitting labour.
We assess the clutch disc, pressure plate, release bearing and dual-mass flywheel while access is available. Replace worn or unsuitable components; healthy parts do not automatically need renewing because the gearbox is out.
The rear main seal, or RMS, seals the crankshaft and is a different component from the IMS bearing. A leak at the engine–gearbox joint needs its source confirmed. A sound IMS bearing will not cure an RMS leak.
Ask for one combined quotation for Boxster clutch replacement, any necessary rear main seal work and the bearing. Shared labour should be counted once. Tiptronic cars have different access and parts requirements.
Keep a suitable engine healthy
A preventive retrofit belongs in an engine suitable for continued use. Before committing to installation, we review its history and check for signs that more extensive work is needed.
The agreed checks can include the oil filter and sump, engine behaviour, camshaft timing data and further cylinder testing where indicated. A clean filter or a fault-code scan cannot certify that an IMS bearing is healthy or predict how long it will last.
When to switch the engine off
Stop safely for a red oil-pressure warning, heavy mechanical knocking or sudden severe rough running. If metal debris has been found in the oil, avoid restarting the engine until it has been assessed. These signs need investigation and do not, by themselves, identify the IMS bearing.
Confirmed bearing failure can contaminate the engine and disturb valve timing. We explain Boxster engine repair, rebuild or replacement options when a simple retrofit would be inappropriate. Call to arrange suitable collection.

- Any warning, oil leak, unusual noise or metal found in the filter.
The installed engine and bearing arrangement determine whether an external retrofit is possible. We confirm suitability before quoting the repair.
Boxster IMS bearing questions
Can an IMS bearing fail without warning?
Yes. A bearing can deteriorate without an obvious noise or warning light. Waiting for symptoms is not a reliable maintenance plan. Review the fitted bearing, engine condition and service history to decide whether preventive replacement is appropriate.
Does low mileage mean I can leave the original bearing?
Low mileage alone does not establish its condition. Age, storage, maintenance and the installed design also matter. There is no universal mileage at which every original bearing fails, and we do not use a fixed failure percentage to predict your individual engine.
Will a diagnostic scan confirm the bearing is good?
No. A scan can reveal relevant engine faults, but it cannot inspect the bearing internally or guarantee its remaining life. Checks of the filter, sump and engine condition help determine suitability for a retrofit; they do not eliminate every future risk.
My Boxster already had an IMS upgrade. Does it need another?
Check the invoice for the kit name, fitting date and mileage. Ball- and roller-bearing replacements can have scheduled renewal intervals. A pressure-fed plain-bearing conversion is different. If the record only says “IMS done”, ask the original installer for the part details before deciding.
Can you replace the bearing without removing the engine?
An eligible externally serviceable bearing can usually be replaced with the engine assembled after removing the gearbox and relevant surrounding components. The larger internal bearing in most 2006–2008 engines needs engine disassembly. The fitted engine and gearbox determine the actual access.
Is an oil leak proof of IMS failure?
No. The rear main seal, IMS flange seals and other engine seals can leak for different reasons. The leak must be located. Replacing the rear main seal does not automatically mean the IMS bearing has been renewed.
Will a replacement stop bore scoring or every engine problem?
No. An IMS replacement addresses one bearing arrangement. Cylinder bore scoring, cooling faults, oil-pressure problems and worn timing components are separate concerns. Existing internal damage can make an engine unsuitable for a preventive retrofit.
What should I send to request a quote?
Start with the Boxster model year, mileage and whether it is manual or Tiptronic. Add any IMS or engine replacement invoices, and the VIN if available. Tell us about warning lights, noises or metal found during an oil change. The workshop will confirm what further identification or inspection is needed.
