  • SBD have designed this rod to replace the standard fragile item, it has a bronze small end bush, which replaces the press-fit version. Ideal for use with our piston. These rods have been tested extensively to over 9000rpm on standard crankshaft & over 9500rpm on a steel crankshaft.
    So beware of cheap imitations!
    Weight approx 455g
    Centre to centre length approx 146mm
    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 improvement, the hole is simply filled with oil and the pressure in this area is maintained.
  • The new 152 con-rod has been designed specifically to go with our new 2-litre Duratec slipper pistons, it is 6mm longer which has helped to reduce the rod angle which in turn helps to increase the torque. On our high spec engine we saw an increase of 6lbft torque & just reaching 200lbft torque. Due to the smaller pin size on the piston, this has reduced the weight of the small end of the rod which means the rod is actually 12g lighter than our normal Duratec rods. We have also upped the rod bolts to the ARP625+ high spec material to cope with the extra performance.

  • The Omega pot type pistons are extremely high quality and SBD have used them since they first started. The piston crown has been developed over time to what we believe is the best pot type piston available, in fact when tested against other makes of piston, they regularly out perform even those types which are supposed to be a slipper style. If you have a reasonable budget which is not able to stretch to our high specification Omega slipper pistons, choosing our Omega Pot type piston is an essential way to gain performance and reliability at the right price.
    Available in 87.50mm and 88.00mm bore.
  • SBD have designed a 2 ring slipper piston for the 2-litre Duratec with the help of Omega & the latest improvements in design that they have gained through GP bike development, they have produced a new forging specifically for this piston. It is of a much stiffer construction, uses a smaller lighter pin at 18mm, they have also moved the pin closer to the crown of the piston which helps to reduce piston rock which also helps to reduce friction. It is ultra-lightweight & low friction; in initial tests we saw a 7bhp increase in our high spec engine simply by changing the pistons along with new matching longer rods. Available in 87.50mm and 88.00mm bore.
  • SBD 2.0L XE 143mm Saenz Steel Rod Set

    £675.00 £810.00 Inc VAT
    2.0L 16v Steel rod set 143mm, suitable for standard crankshaft.
    Manufactured by Saenz to SBD'S design.
    Suitable for use with SBD/Omega pot pistons.
    Weight approx 516g.

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.

  • 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.

  • 2.0L XE Omega/SBD 87.00mm Pot Piston set.
    The Omega pot type pistons are extremely high quality and SBD have used them since the company was founded. The piston crown has been developed over time to what we believe is the best pot type piston available, in fact in many cases when put up against other makes of piston, they regularly out perform even those types which are supposed to be a slipper type. If you have a reasonable budget which is not able to stretch to our high specification Omega slipper pistons, choosing our Omega Pot type piston is an essential way to gain performance and reliability at the right price. Suitable for use with either standard rods or our 143mm Saenz Steel Rod Set.
  • 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
  • SBD Hayabusa Drysump Kit

    £1,025.00 £1,230.00 Inc VAT

    OS-DSK-BUSA-01

    The SBD Hayabusa dry sump system is in our opinion the most successful and efficient kit on the market, they are now sold worldwide.
    The kits are supplied direct to some Kit Car manufacturers and we are pleased to say the our dry sump systems have been highly successful in many disciples, including: the Danish Seven Racing Champion Steffen Hansen and the American Salt flats speed record bike.

    Key Factors in our Design

    Remote PRV (pressure relief valve) housing for pressure stabilisation
    After various tests and prototypes, we found the standard PRV position causes pressure fluctuations due to the valve no longer being submerged. We have engineered a remote housing with oil recirculation.
    Pump removal in situ - no need to remove sump
    The twin stage scavenge oil pump, which replaces the original water pump (you will need to use an electric pump) has been designed so it can be removed and fitted whilst the sump is in place, this allows the user to inspect many components without having to remove the sump or disassemble the engine further. The pump mounts directly to our billet dry sump pan without the need for any hoses.
    Internal scavenge channels
    The sump was designed in 2 neat pieces; the main part of the sump has channels machined into it allowing the dry sump system to scavenge oil from both front and back of the sump pan, so there is no need for any external scavenge pipes. The pan is then closed with a thin top plate, which is bonded to the main part of the sump pan. You will only need to provide a supply from your dry sump tank & a return to the tank (via oil cooler if required).
    M8 mounting lugs for semi-stressed applications
    We have also added 4 x M8 fixing holes to 31mm deep sump pan. The billet is extremely rigid and these mounting lugs allow the user to bolt the sump to a chassis of a car, if required to further increase the strength of their installation.
    No baffles required - faster oil evacuation
    There are several reasons why we have not fitted a baffle plate. A baffle plate is designed to retain oil below it, so if the engine was wet sump there would be oil in the sump itself and as the vehicle corners, the baffle is designed to slow the oil movement beneath the baffle to stop it escaping. When an engine is dry sump, in theory there is no oil in the sump itself and therefore the baffle becomes an unnecessary component as there is no oil to retain. The other problem with using a baffle is that any oil that is falling into the sump itself will be slowed by the baffle, but in effect this is the opposite to what you need and any oil that is making its way to the sump should be allowed to reach it as quickly as possible, because the moment it reaches the sump the scavenge pumps then extract the oil and return it to the tank as quickly as possible.
    Standard oil cooler delete
    The standard oil cooler option has been removed from our dry sump system, because there was always a considerable oil pressure drop when used. Whatever we tried, there would always be a pressure drop and as many Hayabusa owners would know, oil pressure is quite high when the engine is cold and as the engine heats up and the crank cases would grow, oil pressure would drop huge amounts. We have even seen oil pressure of 2PSI at tickover, if you only fit the oil cooler to the scavenge side, the pressure part of the system does not have to work as hard and we have seen significantly more oil pressure under all temperatures.

  • 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.
