Our Latest Advert revealed in Evo and Performance Vauxhall magazines.
Saturday 16th May.
We had a varied selection of cars turn out for the VxDC Rolling Road day on Saturday 16th May, 2.0 16v Turbo Z20LEx engines being the most popular offering due to the wide range of tuning options available for this popular engine.
We were fortunate to have good weather, with sunshine for the most part of the day and a very good turnout of cars and people.
Thank you to everyone who attended the day and made it an enjoyable one.
Look out for the feature in a forthcoming edition of Performance Vauxhall magazine.
There is just something about the lines of a classic 911…. we had this immaculte car in recently for headlight bean alignment and MOT.
Turbosmart Kompact Shortie Series Recirculation Valves have been specifically designed to suit BorgWarner EFR and KKK turbos.
Unlike the standard, plastic valves that use un-reinforced rubber diaphragms and are known to crack or split under increased boost, the new BW/KKK Kompact valves uses an O-Ring sealed piston which, coupled with their billet aluminium construction give them over 30PSI of boost handling capability.
Designed as a bolt-on direct replacement replacement for the factory valve on all BorgWarner EFR, KKK turbos, the Kompact Shortie Plumb Back provides better boost response and greater boost handling capability.
Included with each Kompact Shortie kit is:
Finished in Black as shown. This recirculation valve is a really nicely machined and finished item, with a quality look and feel about it.
Features and Benefits:
Suitable for ALL BW EFR KKK (K04/K06) Z20LEx and A20NFT Turbo units:
Astra G SRi/GSi 2.0 Turbo
Astra H SRi 2.0 Turbo including VXR
Astra J GTC VXR 2.0 Turbo
Zafira A GSi 2.0 Turbo
Zafria B SRi 2.0 Turbo including VXR
VX220/VXR220 2.0 Turbo
Coming soon for Z16LEx 1.6 Turbo Vauxhall Engines.
This Astra H VXR Nürburgring came to us for an uprated CSRacing clutch and lightweight billet steel flywheel, due to the fact the factory clutch had started to slip occasionlly.
The car had covered a shade over 91,000 miles and was originally modified to Stage 3 in 2008 at around 3,500 miles, virtually from new. So for nearly 7 years the car has been running at between 290-305bhp having had further changes made in later years, and the factory clutch and dual mass flywheel have given an exceptional service life considering the huge increase in power and torque to the car.
Replacing the original dual mass flywheel for a solid (single mass) lightweight billet steel one reduces the flywheel weight giving better acceleration due to the engine’s willingness to rev more freely as it is not having to rotate such a heavy mass. The CSRacing uprated clutch is a stronger unit, with an uprated cover with much more clamping pressure and an uprated sprung organic clutch disc to work with the single mass flywheel. The sprung disc is essential to fit if the dual mass flywheel is removed and replaced with a single mass item.
Also fitted at the same time was an uprated polyurethane gearbox mount insert as the original factory mount was starting to show signs of age related fatigue.
Don’t forget we can also fit standard original equipment (OE) replacement parts as well as uprated parts!
Recently in for some fairly extensive modifications were this brace of VX220s.
The 2.2 underwent a Stage 1 supercharger conversion, an uprated fuel pump with 48L alloy fuel tank and rolling road set up.
The turbo model had a chargecooler system fitted, along with uprated fuel pump and uprated clutch, 80mm air flow meter and 495cc injectors, followed by a full rolling road mapping session, to complement the already fitted VXR turbo and full exhaust system.
We prepared a second subframe and fitted the uprated bushes to it prior to fitting it to one of our track day cars.
Astra H Subframe with uprated purple road spec polyurethane subframe bushes fitted.
Astra H Subframe with uprated black track spec polyurethane subframe bushes fitted. This is due to be fitted to our track car. The front anti roll bar and power steering rack will be swapped over onto it.
And some close up shots:
6 complete bushes required per subframe. Kit includes 12 ‘top hat’ type bushes, 6 stainless steel sleeves/inserts, 12 zinc coated upper and lower washers and a grease sachet.
Enhancements being carried out to the brakes and suspension on an Astra H 1.9CDTi (150 PS) 3 door sport hatch.
To improve the chassis our Courtenay Sport Clubman Plus fast road suspension upgrade was fitted, which is a full kit that includes original equipment (OE) genuine Astra VXR dampers and a set of DAP Road springs, which not only improves road holding but also lowers the car by around 25-30mm.
The front and rear brakes were upgraded with EBC Turbo Grooved front and rear discs with EBC Red Ceramic (fast road) pads all round, and the system was bled with DOT 5.1 fluid.
Type 2120 – Turini. 8″x18″, 65.1mm, 5x110PCD ET38mm (possibly ET35mm) for Astra H VXR fitment.
We would like to have these Speedline Turini flow-formed 18″ wheels manufactured for Vauxhall/Opel fitment. If there is enough interest we will get a small batch of wheels made in 3 colours: Silver, Anthracite and Gold. The flowforming process makes these wheels extremely strong and light. They are fully heat treated up to motorsport specification and ideal for trackday use.
This would be a limited production run of wheels, meaning we do not need huge numbers of people to get this moving for delivery early 2015, and limited numbers would mean a certain level of exclusivity.
Target Price £936.00 per set of 4, depending upon the level of interest. (List Price £1008 inc VAT)
Please contact us as soon as possible to confirm interest giving your preferred colour. There is a contact form at the end of this post. If we achieve the desired numbers an order will be placed with Speedline upon receipt of payments from all participants.
Specification: 8″x18, 65.1mm, 5x110PCD ET38mm (possibly ET35mm) for Astra H VXR/OPC fitment. Will clear big brake kits such as AP 4 Pot and K Sport 8 Pot/D2 6 Pot.
These will not require a ‘fitting kit’ (spigot rings) or wobbly wheel bolts.
Gold suits White and Arden Blue cars.
Anthracite suits Silver, Red and White.
Silver suits most colours.
An iconic Speedline design, the Turini wheel is known for it’s classic good looks, durability and light weight.
The wheel comes with the ‘seal of approval’ from some of the worlds most important car manufacturers, as an original equipment option or line fitment. The 18″ version employ the world renowned Speedline patented Flowforming production technology, ensuring the ultimate marriage of low weight with high strength.
NOTE: These wheels are listed as available online on other suppliers’ websites, however having spoken directly to Speedline they have confirmed there is no stock of these wheels in a correct Vauxhall fitment, except by placing a minimum quantity special order.
FLOWFORMING – What is it and how does it differ?:
Speedline’s flowforming process is a unique solution to a common problem – how to make a wheel both light and strong.
Speedline’s flowforming method is unique within the wheel production industry, and patented.
This means that only Speedline can provide this precise technology.
The casting used to produce the wheel is much narrower than usual, but with the same amount of alloy that would be present in a conventional casting.
The casting is then placed in a specially designed machine within an additional mould. The hot casting is then spun at high rpm within the mould, and formed into the shape of the final wheel.
The resulting grain structure within the alloy of the wheel is linear, flowing in a single direction (see image below).
This grain structure pattern (shown above), combined with the exceptional quality of casting required for the process, gives the rim area of the wheel huge mechanical strength, and elongation. As a result of these mechanical characteristics, Speedline are able to reduce the thickness of the rim area resulting in reduced weight, without compromising strength and resistance to impact (see images below).
As can be seen from these images above, the flowformed wheel rim profile is much thinner that the usual cast wheel, resulting in lower weight and reduced inertia, making the wheel respond faster to acceleration and braking forces.

We had this Astravan 1.9CDTi here recently for a few days undergoing some fairly extensive upgrades to cover the engine, brakes and chassis.
A Stage 3+ conversion. The van was fitted with our hybrid turbo charger, full 2.5″ stainless steel exhaust system (turbo back), full height CSRacing Intercooler and 80mm Air Flow Meter with revised inlet air path. At the same time an oil and filter change was also carried out.
After the hardware had been fitted, it was round onto the rolling road for ecu remapping and a full set up, which achieved 223bhp and 377 lb ft torque.
At the same time a K Sport big brake kit was fitted, under the 17″ wheels, to greatly improve the stopping ability over the original factory 308mm brake set up. Red 8 Pot calipers, 330mm x 32mm 8 grooved and ventilated front discs with EBC Yellow Ceramic Pads. The brake system was bled through with DOT 5.1 brake fluid.
To ensure adequate clearance between the wheel spokes and the calipers a TÜV approved 3mm spacer has been fitted with longer 28mm black wheel bolts.
The van has also had our Courtenay Sport Clubman Plus fast road suspension upgrade which is a full kit that includes original equipment (OE) genuine Astra VXR dampers and a set of DAP Road springs, which drops the chassis significantly, as can be seen on the before and after pictures below. Ideal for fast road and light track day use.
The magnet is secured in place with a proprietary 2 step process and will never come out. Advancements in technology and materials means Gold Plug is continually evolving and at the forefront of technology.
The strong Neodymium magnet collects any swarf or wear particles missed by the oil filter. These particles are abrasive and potentially damaging to the engine. The magnet will hold any collected metal firmly, unaffected by temperature variation until the oil is changed.
Magnetic sump plugs are a proven product and even used by some manufacturers as standard, examples are available on the market today however few match the quality of Gold Plug and those that do are very expensive.
Some Vauxhall/Opel engines using M14x1.5 Sump Plugs:
X18XE X20XEV X25XE X30XE (FWD)
Z10XE Z12XE Z12XEP Z14XE Z18XE Z18XER Z32SE
1.6 Turbo: Z16LEL Z16LER Z16LET
2.0 Turbo: Z20LEL Z20LER Z20LET Z20LEH
1.6 Turbo: A16LER A16LET A16LES

We had this 2009 Insignia VXR with us recently for ecu remapping and full set up. It had covered about 55,000 miles and had already had the second cat removed by the owner, with the pre cat still in place.
Mapping and set up resulted in 348 bhp and 396 lb/ft torque, up on a car with a remap and standard exhaust with both cats still fitted, with gains of almost 100bhp and 100 lb/ft torque throught the mid range.
We had a lovely 40 something thousand mile Corsa VXR in with us recently which had been fitted with a full 3″ exhaust system, twin silencers and pre cat removed and also our high flow CSRacing full height intercooler.
Compressions were checked all found to be good, then the ecu was remapped and the car underwent a full rolling road set up with full ecu datalogging and the software was optimised to suit the fitted components resulting in 240bhp and 249 lb ft torque and running on 99 octane fuel.
As we are sure you all know what a Corsa VXR looks like by now, we will show you the power and torque graphs instead:
Due for imminent release, expected within the next 3 weeks, uprated engine mounts for Corsa D VXR models.
Pricing from £93.60 – £138.00 Further details to follow. Contact us now to pre-order yours.
It has been a busy week for us for Corsa VXR tuning.
This Glacier White car is our second Corsa VXR Nürburgring Stage 2 Upgrade in a week. We fitted our full 3″ turbo back exhaust first:
Followed by custom mapping, datalogging (including ignition timing, knock retard, injectors, boost pressure, fuelling), map optimisation to suit the new exhaust and full rolling road set up:
A busy week for remapping Corsa VXRs on our rolling road with this A16 engined Corsa VXR in for mapping, injectors and set up earlier in the week, reaching a respectable 217bhp for a car with a 70mm cat back exhaust.
Another Garrett build, with Garrett GT30 Turbo, V Band Manifold, Courtenay Klasen Cams and Inlet Manifold, Engine rebuild, 90mm AFM, injectors, 3″ exhaust; all the usual requirements for a Garrett conversion, previously mapped by us and making a respectable 490bhp; brought in for checking now its a little cooler. Up 13bhp to 503bhp due to the lower temperatures.
This Astravan with Z20LEH engine, steel rods and GTX2867 garrett build was brought in for mapping and full rolling road set up.
The map it was brought to us with (which was not our software) was checked first and shown to be running 320bhp, with some fuelling and ignition timing issues.
We switched to a 3 bar map sensor (from a standard 2.5 bar one) and recalibrated the map so the ecu could correctly read boost pressure as the 2.5bar map sensor will go out of range on capable of reading up to 22psi of boost, hence the change to a 3 bar sensor. Correctly recalibrated the ecu can then read up to 29.4psi boost presure.
Also changed were the 875cc injectors to a much more suitable 630cc injector for the required power, again with suitable ecu recalibration. 875cc injectors for the required power prove way too big, and cannot be controlled accurately enough for part throttle fuelling (essential on a fast road car) due to the spray pattern plus fuel consumption will be higher, again another consideration for a car with road manners. When checked and datalogged first this car was running at 0.88 lambda on cruise, so clearly the map needed some work at this point. This is too rich and can cause bore wash and potentially internal engine damage. Big injectors are fine for stand alone management and for race cars which do not run at part throttle or cruise, but were just incorrectly specced for this particular applcation.
With a couple of bits still to do and after mapping and set up the result for now is 390bhp and much better, more controlled fuelling at part throttle and cruise. Fuel consumption will improve as well as 630cc injectors control part throttle fuelling more accurately.
Why the change of injectors? For better road manners; in simple turns the bigger injector (875cc) does not atomise the fuel as efficiently at slow duty cycle/engine speeds. So a 630cc injector can provide more than enough fuel for the power but still return better fuel economy due to its ability to better atomise the fuel.
Following our very successful and much acclaimed DAP R Astra H VXR spring kit we now have our DAP R Astra J VXR spring kit available.
Vauxhall set the bench mark very high with the original Astra J set up which didn’t make our job very easy however after an extensive period of development we have achieved what we feel is the ultimate fast road set up.
Visually the car now sits typically between 20-25mm lower. The straight line ride quality is slightly firmer but not at the detriment of ride quality and certainly does not feel crashy, however press hard into the corners and the suspension tightens, firming up giving more control through mind corner bumps and undulations whilst communicating with plenty of driver feel and feedback.
DAP Rs are wound from high tensile chrome silicone steel and are manufactured in a cold winding process for maximum durability in all weather conditions. They are powdered coated Diamond Black to give a very OE look and feel and have the DAP signature discreetly placed on them.
This lovely 2012 Corsa Nürburgring in Lime Green Pearlescent was brought to us for a Stage 2 upgrade, so initially into the workshop and up in the air so the original exhaust could be removed to be replaced with the full 76mm (3″) turbo back stainless steel exhaust system:
and then onto the rolling road for custom mapping, datalogging (including ignition timing, knock retard, injectors, boost pressure, fuelling), map optimisation to suit the new exhaust and full rolling road set up:
