Choked Porsche Panamera Intake: Get Some Nuts

This poor-running Porsche Panamera was the first service car to benefit from our latest investment in workshop equipment: a mobile Nederman dustless media blaster. Arriving in the JZM Porsche service workshop with terrible running and a string of fault lights showing, a PIWIS check directed our diagnosis towards the intake. Stripping the intake manifold from the engine, we soon found the valves to be clogged almost solid, following a life sitting mainly in London traffic.

The only way to fix this problem would normally be to strip and clean the heads and valve train – quite an expensive process. We could have used our high-power blast cabinet to great effect but would still have had to strip the heads off. Talking to our equipment suppliers, we came across the dustless Nederman system, using crushed walnut shells.

Turning the engine to top dead centre on one cylinder so the valves are closed, the machine blasts the backs of the valves with walnut shell media, simultaneously removing waste products. The shells are combustible, so any small fragment which manages to find its way into the combustion chamber will just be burned off without damaging the engine. The results were terrific and we will find many more uses for the new blaster!

Porsche builds the millionth 911

Porsche has just announced the production of 911 number one million. An Irish Green 991 Carrera S was the millionth Porsche 911 to be built since the model’s introduction in 1963 and the car was instantly transferred to the Porsche Museum collection.

The 911 remains the most strategically important model in Porsche’s entire product range and makes a huge contribution to maintaining Porsche’s position as one of the most profitable car manufacturers in the world. Last year, a staggering 32,365 Porsche 911 models were delivered worldwide and the many model variants satisfy a wide range of sports car buyers who also need a certain degree of practicality.

Unsurprisingly, today’s 911s are vastly bigger than the original cars from 1963, but Porsche insists it has never strayed from the founding concept of its rear-engined sports car. “We have continued to enhance the technology of the 911, refining and perfecting the sports car”, says Oliver Blume, CEO of Porsche AG. “This is why it remains a state-of-the-art and technically innovative vehicle. We have also been able to expand the model line very successfully through derivates.”

Porsche is not selling the millionth 911. The car will eventually take up a position as part of the Porsche Museum collection, but, before that happens, it will embark on a world tour, including “road trips in the Scottish Highlands, around the Nürburgring and in the USA, China and beyond”. What’s beyond China? We are keen to discover.

JZM Porsche Market Report April 2017

The used Porsche market has been unaffected by the snap General Election and continues to demonstrate appetite and energy for the right cars at the right price. The evergreen question is just what the right car and right price might be.

We inspect many cars every month and reject the majority of them. This is not marketing speak: we even installed a special inspections lift in the showroom due to the number of inspections carried out week after week. What passes muster are genuine Porsche cars in the very best condition we can lay our hands on.

The earliest water-cooled 911s now go back twenty years, but they emerged at a time when a reliable network of trained Porsche specialists had evolved around the air-cooled cars. Once the cars left dealer network servicing, owners tended to hand the cars to their chosen specialists, so it is easier to find a water-cooled 911 with good service history. This is especially true for Turbo and GT models, as their values never dropped to the point where they would not have been maintained professionally.

This service history audit trail is harder to find on air-cooled 911s, so we are often left relying on what we can see. Looking in the hot spots of an air-cooled 911 will tell quite a bit about how it has been used and maintained, especially when that inspection can be compared to hundreds of similar inspections carried out over our thirty years of working on air-cooled 911s and 930s.

The point is that we inspect everything and question-mark cars are simply not brought into stock. When a car does arrive in the showroom for sale, our customers know that it has met expectations and it is very likely to pass their own inspection. We do not retail models with engine trouble concerns, and all of our cars are warranted. Therefore we have the best stock available – all cars we would like to own personally. So our view of the market is based on retailing the very best cars available.

Our approach may be summed up in six words: “buy fair, sell fair, be fussy”. We are very fussy and sensible (bordering aggressive) on price: that is why we sell cars. In the last seven days we have sold ten cars, including a paint-to-sample RHD 991 GT3 RS, paint-to-sample RHD 997 GT3 RS 4.0, RHD 3.2 Speedster with 10,600 miles, Martini Edition 930, Gen II 997 GT3 Club Sport and a Boxster Spyder in Black.

These cars had a number of things in common: they were presented in perfect condition and passed JZM inspection. This proves that if you buy the right car and sell at the right price, there is a healthy market ready and waiting. Some may claim this market for the best examples is purely collector driven, but that is simply not the case. We sell cars to first-time buyers, overseas customers, track day clients and many other people who are keen to own a high quality used Porsche. It is not all collector activity.

And the market is not all 911s. Caymans are doing well, especially Cayman GTS with the right spec. GT4 is a little harder to move as there are simply so many cars on the market and many are well and truly overpriced. There are no buyers out there for overpriced GT4s and there have not been for many months. Our superb Cayman GT4 with less than 500 miles from new is priced almost £20,000 cheaper than the most expensive GT4 currently for sale – it is time for other sellers to have a good look at their prices and bring some energy back to this corner.

The fine weather has brought Boxster into sharper focus and we have sold a number of very nice Boxsters so far this year, including a selection of beautiful Spyders. Spyder is a good seller but only when presented with the right specification. These cars are super sensitive to spec, so it is important to be aware of what fits best. When it comes to Boxster Spyder, bucket seats are an important part of this formula.

From the 911 lines, everything has potential when in the right condition. Our upcoming part exchanges include a nice 997 Carrera 4 S Coupe and a 996 Turbo S Tiptronic Cabriolet with special order leather trim. We have possible buyers for both on our books. GT cars continue to be where most of our business is done, but all models are of interest to us.

As May 2017 begins, the weather is good and the mood is upbeat. Top condition cars are selling and that is correct for this time of year. If you are considering selling your Porsche, why put it anywhere else? Contact us to discuss brokerage or an outright purchase.

JZM Porsche Market Report March 2017

Now that the clocks have gone forward and the bright evenings are with us, we have entered the often-mentioned Porsche ‘season’. Owners of older Porsches have started to get their cars out of storage and use them more regularly, leading to 911s and other classic Porsche models becoming a more common sight on the road.

This increased activity/visibility of the older Porsches has a noticeable effect on the used Porsche market as a whole. With more cars out and about, the unique attractions of Porsche ownership – particularly older models – are brought to the fore and enquiry levels at independent dealerships increase. This is when we begin to see the trends for demand (and therefore prices) emerge for the year ahead.

Enquiry levels through February and March prove that the market remains in good shape. We’ve welcomed a steady stream of potential buyers and feedback on condition of our stock and asking prices has been very positive. Many cars have sold within hours of arriving at JZM and regular visitors to our all-new website will have noticed a considerable intake of interesting and highly collectable Porsches through the winter months. With so much attention on collectable Porsches during the ‘off-season’, it is easy to forget that the majority of owners buy their Porsches to drive them.

Porsche cars for driving remain in strong demand. Recent weeks have brought many quick sales for a variety of drivers’ cars, including a Gen 1 997 GT3 RS prepared by JZM for track use that had enjoyed track days all over Europe (and will continue to do so), a well-specced Cayman S manual in rare Rhodium Silver and a trio of smart Porsche Cayman Rs. Also sold in short order was a perfect 991 Carrera GTS manual in Lava Orange, the beautiful Porsche 356 ‘Outlaw’ Coupe and a pair of 997 Turbos, one of which had been tastefully modified here in the JZM tuning workshops with KW 3-way adjustable suspension, upgraded exhaust and an RS flywheel and clutch.

We find that cars which have been modified with care and attention using quality parts continue to sell well. JZM offers only the best quality aftermarket Porsche tuning parts, guaranteed to improve performance over a standard car. Parts of this quality tend to be quite sought after by keen drivers, so cars with average mileage offered with these modifications usually sell for higher prices than standard cars – quite a different situation to low mileage cars, which do better in factory spec.

The rising prices for low mileage cars have caused many owners of average mileage examples with interesting modifications to return their cars to standard, which generally makes them less interesting to drive and can keep the cars in the garage. This approach is unrewarding on a number of levels: cars that do not get used can cost more to maintain.

It is always better to use and enjoy Porsches with average mileage and if that means leaving aftermarket upgrades in place for a better drive, then owners should do that. Any price rise for a standard-ised car may be completely wiped out when potentially paying additional maintenance for lower use. “Drive and enjoy” remains the best philosophy.

Regarding what’s hot and what’s not, air-cooled enquiries have definitely picked up with the arrival of spring and we have sold some great air-cooled 911s this month, including our low-mileage Speedster in Black, 964RS in Silver, the Falsen Green 930 Flatnose and a beautiful 993 Carrera 4S in Violet Metallic. We still have some very interesting air-cooled cars in the showroom and all have strong enquiries listed against them.

We have enquiries on file for most water-cooled 911s, so many of these cars sell as soon as they pass our inspection and before they are advertised. Recent low-mileage sales include a superb Gen II 997 GT3 Clubsport with less than 12k miles, which had a number of names against it before it arrived. The car was offered to existing enquiries in order and the first potential buyer snapped it up.

Elsewhere in GT3s, the Gen 2 991 GT3 announcement generated some interesting phone calls and discussions about brokerage deals to raise cash for a GT3 order. The reality is that 991.2 GT3s will be just as hard to order as Gen 1s, so make sure you have a confirmed order before selling the car you already own. Buying a Gen 2 GT3 in the hope of securing a place on the list for the next GT2 may not be enough to guarantee a spot: Porsche simply will not make enough cars for those 911s to be offered to the regular man in the street (including us – we share your pain).

All water-cooled Turbos remain in demand and we have RHD 996 GT2 and Clubsport and even a RHD 997 GT2 RS coming in. All of these cars have enquiries listed against them and will probably sell to clients who have waited patiently for the right cars to come up. Really good 997 Turbo manuals are still in demand and Turbo S 996 or 997 are also excellent news. We are buying as many of these cars as we can find that pass our pre-sale inspection and outbidding all other dealers, so contact us if you have a car available.

Akrapovic upgrade exhaust for Porsche 991.2 Carrera (Turbo)

JZM is delighted to be the first UK supplier of the all-new Akrapovic exhaust system for Gen 2 991 Carrera models. Designed to replace the factory sports exhaust, the new Akrapovic system for the now turbocharged Carreras is manufactured from ultra-lightweight, heat-resistant titanium alloys, which have been coated for increased durability.

Part of Akrapovic’s highly regarded ‘Slip-On’ line, the system tops the scales at two-thirds the weight of a standard exhaust. Thanks to much improved gas flow through the exhaust’s central silencer and out through titanium tailpipes, performance is greatly enhanced over standard. Buyers also have the option of a stainless steel link pipe set, complete with sports catalytic converters and a stunning carbon-fibre diffuser.

Delivering less weight, more performance and increased visual impact, the new Akrapovic system is a perfect addition to our range of high end tuning products for Porsche models. Email Steve McHale to discuss any of our Porsche tuning products or visit the JZM Porsche tuning shop.

Porsche 911 Turbo Flatnose (930) for sale

Born of the Porsche 935 racing prototype which dominated motorsport for many years after its introduction in the mid 1970s, the flatnose was the rarest 911 of them all: a symbol of true wealth and power. While the styling eventually slipped out of fashion for a time, a proper flatnose Porsche 930 Turbo is now regarded as a truly iconic machine.

The latest Flatnose Porsche 930 Turbo to grace the JZM showroom is this beautifully presented 1986 example in rare Falsen Green Metallic. With just 30,000 miles from new and benefitting from a recent high quality repaint costing over £12,000, the flat six powering this stunning flatnose 930 has been professionally upgraded to include a double-size twin-element intercooler, an uprated wastegate and fuel system to accomodate higher boost pressure and a twin 100mm outlet sports exhaust system for extra oomph.

The legendary 930 brakes have also been modified utilising later larger calipers. The car is fitted with an internal brake balancing system that can be operated from within the cabin. A 40% Limited Slip Differential helps to keep this powerful 911 on the straight and narrow.

Priced very attractively considering the excellent condition, comprehensive maintenance history and substantial recent investment, this unique RHD flatnose 911 Turbo is available for immediate delivery and long-term delight from JZM Porsche. Email JZM Porsche Sales to discuss.

As last of the air-cooled line, the 993 took advantage of everything Porsche had learned about rear-engined sports cars up to that point.

KW Suspension for classic Porsche 911 SC

We’ve just fitted KW Suspension’s latest V3 kit for impact bumper 911s to this 1979 Porsche 911 SC. The conversion from standard Bilstein struts and rear dampers to the adjustable KW kit was very straightforward. We also took the opportunity to change the rear spring plates complete with suspension bushes and covers as the originals were in a pretty bad state.

Our photos show just how much wear the spring plate bushes had endured since 1979: almost forty years ago! Such wear is common on an old Porsche and causes big changes in suspension geometry under acceleration and braking. Sudden geo changes are the root cause of the dangerous rear-steer characteristics found in many older 911s. Suspension bushes deserve careful inspection every service and replacement when worn.

KW’s latest suspension kit is one of two full kits suitable for the impact bumper 911s. The kit fitted to this Porsche 911 SC uses the original torsion bar setup, while the track-friendly Clubsport kit does away with the torsion bars and goes to full coilover suspension. This would be overkill for purely road-use 911s. The V3 kit with its galvanised steel body and adjustable rebound and compression certainly impressed our very own tame racing driver on road test, following a full 4-wheel alignment once the new dampers had been fitted.

“The new KW suspension feels great on this classic 911,” said JZM Technical Director, Steve McHale. “Not too stiff but solid on the road. By replacing the old parts with modern KW dampers, the car feels planted and confident. This kit is the perfect upgrade for cars with older, worn-out dampers, especially when the suspension bushes may also be in need of replacement.”

Email JZM Parts to discuss fitting details and prices for the V3 kit for impact-bumper 911s including the Porsche 911 SC, Carrera 3.2 and 930 Turbo models.
