  • When using slipper pistons there are a lot of stories around, but most of these tales have come from using inferior products.
    SBD have used Omega slipper pistons for many years now and find they are, in fact, more reliable and create less wear than any other design of piston, whether used in rally, race, sprint or hillclimb engines.
    When you wish to produce the ultimate engine, the Omega slipper piston would always be our first choice.
    SBD have taken all the latest advancements in technology and together with the improvements they have discovered from their engine developments used this to design a completely new piston for the ever popular 2.0L XE. Omega have produced a completely optimised forging, it has significantly increased strength over any piston SBD have produced in the past and great care has been taken to ensure no machining is required to the internal structure in order to maintain maximum strength.
    SBD have reduced the pin size from the previous slipper design of 20mm down to 18mm (STD is 21mm), and then been able to reduce the piston pocket depth due to their advanced cam designs, this has allowed SBD to reduce piston crown height to improve flame travel within the combustion area and yet still maintain optimum compression.
    Piston weights as follows (including rings, pin and circlips);
    86mm - 298g
    87mm - 307g
    88mm - 314g
  • To compliment the latest XE slipper piston, SBD have designed two new con-rods; one to suit the standard XE crank dimensions (26.35mm big end), which uses an L19 ARP bolt, the second version has a narrower big end (23.80mm) specifically designed for a narrow journal Steel crankshaft and supplied with 625+ ARP bolts.
    SBD have managed to increase the overall rod length to 149mm due to the new smaller pin size of 18mm, this allows the pin centreline to be moved closer to the crown due to its smaller diameter.
    At the same time they have also reduced the overall deck height to allow the standard block face to be machined to ensure perfect accuracy across the top of the block.
    The rod also incorporates the latest designs for improved strength yet is still lighter than the original design.
    This design of rod has several improvements which benefit the engine. There are two vertical grooves on the side of the rod, this directs the oil spray as it exits the big end vertically upwards towards the pin and the crown of the piston,. This has two benefits, it helps to supply lubricant directly to the gudgeon pin also the cool jet of oil to the underside of the crown of the piston helps to reduce the temperature of the piston itself. On the small end, we have repositioned the oil hole which feeds the small end bush. This is because the one at the top which is normally used effectively weakens the rod itself which increases the possibility of breakage when the rod is brought down by the crankshaft. By moving the oil hole to the side of the rod, there is far more material in this area to help maintain its strength.
    Because of the above modifications it is no longer necessary to supply an oil feed through the bearing, even if your bearing still has a hole for the oil jet, it does not reduce its performance as the hole is simply filled with oil and the pressure in this area is maintained.
    Rod weights are;
    510g for the standard width big end rod.
    490g for the 23.80mm narrow rod.
  • Replacement 7.25" (184mm) Pressure Plate for PTT and Super Clutch units. The standard P/Plate has a fulcrum diameter of 6.2", this is the diameter measured across the "bump" points. The High Ratio P/Plate has a fulcrum of 6.0", this is the diameter measured across the "bump" point. The High Mass P/Plate has a fulcrum of 6.2" (Same as Standard P/Plate) however the I.D of the part is smaller to increase the available mass of the part.
  • SBD XE High Spec Taper Throttle Kit

    £1,198.00 £1,437.60 Inc VAT

    TP-VX-2.0-K3

    The tapered throttle body system which Richard Jenvey and Steve Broughton of SBD Motorsport have developed back in 1995 for the 2.0L XE originally at that time for a touring car project which has been so successful, even spawning many copies.
    We decided that the fact that the 2.0L XE was still very popular, that is was time to look at the design again which everything that we had learnt in developing the Hayabusa and Duratec high specification throttle bodies. We contacted Jenvey Dynamics again, who have helped us to develop all our own special throttle body projects over the years and started designing a new intake system to suit the 2.0L XE as well as it's larger capacity versions, 2.2L, 2.3L, 2.4L & 2.5L which are now being built.
    We incorporated all the latest designs and developments into the system and the first prototype was ready for testing for the beginning of December. One of our main dealers had a test engine ready that could have the throttle system tested immediately, so it was shipped to Ivan Orr at Cormeen Motorsport and fitted to his 2.3L XE engine. He carried out back to back tests with our original throttle system in the morning, then fitted the new system and carried out the same tests in the afternoon. The initial results are even better than we had hoped, we saw an increase in peak torque of 14lbft and an increase in bhp of 13bhp, in fact the torque curve had improved everywhere from 2500rpm upwards. Ivan is now getting a 2.0L XE engine ready to carry out a similar test and has already sold the first system to one of his customers.
    The tapered throttle body has a 54mm entry tapering down to a 52mm butterfly. The taper then continues on through the throttle body then into the manifold and down to the cylinder head. The size of the inlet duct where it meets the cylinder head is 48mm wide x 32.50mm high. The port shape we have developed to match up with our high specification CNC ported cylinder head, this means the inlet manifold should not require any porting when mated to one of these cylinder heads. Please download the pdf at the bottom of the page for the TP-VX-2.0-K3 dimensions.
    The injectors are now mounted underneath the throttle body pointing at an upwards direction at the correct angle so that upon butterfly opening high gas speed is achieved allowing very fast throttle response. Because the injector is mounted much higher up the inlet track, this allows improved air/fuel mix, which we have found in many tests to give identical improvements to that seen with an 8-injector set up but also allows for reduced complexity. Great care has also been taken to ensure that the package is very neat and compact as possible, which means we can use a flat air filter back plate without the need for any complex stepped back plates.
    The system comes with a build in single cable throttle linkage mounting assembly, but we have designed options that will allow the use of the more traditional single or twin cable Jenvey throttle linkage kit, see below.
    The overall length of the system including airhorns is identical to the length of our earlier system TP2K. This means that any customers using the original system with 90mm air horns can easily upgrade to the latest system.
    The kit includes inlet manifold, throttle bodies, air horns, fuel rail and throttle cable bracket. It will come assembled, but without the injectors or water elbow TP5 as these depend on your installation.
  • SBD 2.0L XE 143mm Saenz Steel Rod Set

    £675.00 £810.00 Inc VAT

    Manufactured by Saenz to SBD'S design.
