Turbosmart Recirculation Valve for 2.0 Turbo Z20LEx

6 Mar 2015, 10:05

Turbosmart Recirculation Valve
Turbosmart Recirculation Valve
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 using a single spring and increased reliabity over the factory valve.

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 than the factory fitted recirculation valve.

Included with each Kompact Shortie kit is:
  • 1 x Model Specific Valve
  • 1 x Straight Nipple
  • 1 x Banjo Nipple
  • 3 x Mounting screws

Finished: Anodised Black as shown. This recirculation valve is a really nicely machined and finished item, with a quality look and feell about it.

Features and Benefits:
  • Machined from Billet Alluminium.
  • Lightweight, brass/aluminium, two-piece piston.
  • More Reliable than the factory valve.
  • Substancial Construction.
  • Improved Boost Responsive.
  • Single Spring - No Requirement to Change when Tuning.
  • Finish: Anodised Black as shown.

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

£120.00 inc VAT

Coming soon for Z16LEx 1.6 Turbo Vauxhall Engines.

Note:Images show banjo nipple fitted.

Poly Engine Mount Additions

3 Mar 2015, 16:52

At our request, Powerflex have added a couple of new polyurethane engine mount inserts to their Astra H range.

Courtenay Sport supplied the relevant OE engine mounts and asked if a lower front engine mount insert for Astra H 1.9 CDTi models, an insert for the Right Hand Side Mount for Astra H VXR and 1.9 CDTi and an insert for the Right Hand Side Mount for Astra G and Zafria A 2.0 Turbo Z20LET could be produced.

These engine mount inserts fit into and fill the voids in the original bushes and are recommended as a labour saving method of limiting engine movement to improve vehicle performance and reduce the likelihood of engine mount and downpipe failure caused by excessive movement. Some additional NVH may be experienced.

These mounts are now available in both road spec material to reduce engine movement but limit increased Noise, Vibrationand Harshness (NVH) and Black 95 Shore Track spec material, which due to its nature is much stiffer and will lead to significantly more NVH being transmitted.

EBC GD Sport Discs

Black EBC GD Sport Discs

Over the next few months EBC GD Sport Discs will change from gold to black. The current gold coating is being phased out and will be replaced by a Black GEOMET coating, which is a new long lasting corrosion resistant finish.

This means that over the next few months the traditional gold finished EBC discs will be replaced with black coated discs. They will still be manufactured to the same high standards.

Astra Front Wishbones

16 Dec 2014, 16:07

Pre Bushed Front Arm Astra Now Available, we have direct replacement front wishbones for Astra G and H models. These front wishbones are brand new and come pre-fitted with uprated 85 Shore polyurethane wishbone bushes in black and a brand new high quality OEM ball joint.

This will make fitting uprated poly bushes far easier and much more straightforward. No need to spend hours knocking out existing bushes and fitting new ones, simply undo 3 bolts, drop the original arm off the car and fit the direct replacement wishbone.

Priced at £90 each inc VAT.

Poly Engine Bed Bushes

16 Dec 2014, 15:52

Front End Improvement for Astra G/H and Zafira A/B.

Poweflex have engineered a solution to replace the factory engine bed/subframe bushes in Astra G/H and Zafria A/B which can be prone to failure and contribute to vague handling. These stiffer engine bed bushes help improve the front end feel of the car especially during turn-in and cornering. By removing the flex in the subframe bushes the handling is improved giving a more positive feel to the front end.

These Front Subframe Bushes feature two polyurethane top-hat style bushes that makes for simple installation and durability. The bushes house a stainless steel sleeve and are supported by zinc coated steel washers at each end for increased support under load.

Poly bushes will be resistant to corrosion and the addition of a stainless steel sleeve should help prevent the bed bolts from seizing into the bushes, which can happen with the factory bushes.

Suitable for Astra G, Astra H, Zafira A and Zafira B All Models.

These new bushes replace OE part numbers 90498689, 9223022, 9223023 and 13107328 used across the model ranges.

The application of corrosion resistant materials, robust design and the Powerflex Lifetime Warranty ensures the subframe need not be removed again once fitted, unless removal is required for other service work to be carried out.

These bushes are available in Purple Series 80 Shore Road Spec material for vehicles that are mainly used on the road and also Black Series 95 Shore Track Spec material that suits vehicles being used in Motorsport or predominantly on the track.

Purple Spec: £22 each

Black Spec: £24 each

6 bushes required per subframe.

Professional installation is recommended. The ideal time is when the subframe is removed to allow access to the gearbox or clutch.

Speedline Turini Alloy Wheels

13 Nov 2014, 11:37

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.

Colour Suggestions:
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).

Cast versus Flow Forming
Cast versus Flow Forming

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.
