2.0L XE SBD High Specification Taper Throttle Body Kit 

TP-VX-2.0-K4

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.
 
It was redesigned in 2012 to the K3 design, however we decided that since it was still one of our most popular products, it was time to look at it again. We did extensive testing on the dyno and every variation and combination we tried, we couldn’t improve the peak performance of the K3 system. We did manage to find some nice improvements with bottom end torque as well as throttle response by using electronic throttle and an additional set of injectors close to the head on the very high performance versions of the XE. The injector position has been incorporated into the design so the user can upgrade at a later date. (product code for upgrade)We are also producing an EGAS kit (EGAS can only be used on the MBE9A9 ECU or if the ECU you have is equipped with the facility).
 
With the help of Jenvey Dynamics, the throttle body has been made lighter by changing to a 2 bolt fixing with a spigoted location to the inlet manifold. The inlet manifold has also been made lighter because of the alteration to the 2 bolt fixing.
 
We have managed to increase the strength by changing the rib design on the manifold.
 
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.
 
The injectors are 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. However there is now an option to add another set of injectors close to the cylinder head for high performance versions of the XE.
 
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 K3 system and the earlier TP2K. This means that any customers using the older systems can easily upgrade to the latest version.
 
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.
