VintageTreffen, Jeff, etc...The RHD Throttle bodies, purchased directly from RHD in Australia,are basically the throttle bodies in kit form and the assembly instructions are found on the RHD website and consist of a an assembly video and then there is another video that outlines the installation of the assembled ITBS to a 911 engine....the "Home Garage" guy is Rama, the owner of RHD. He is very responsive, if there are questions regarding assembly/install of his product

However, just to clear up some obvious confusion...per the discussion above, the RHD ITB throttle body kit consists of the throttle bodies only, in parts form, ready to be assembled. great product that can be purchased directly from RHD in Australia.

The x-faktory kits are integrated systems...consisting of fully assembled RHD Throttle bodies, the ECU, wiring harness(s) Fuel pressure regulator, fuel and vacuum hoses, o2 controller and sensor, TPS, temp sensor, fuse block, terminal block, etc. Basically everything needed for install and tuning , with the exception of termination spade or ring lugs.

Documentation consists of an End User's Guide with install and tuning info, manufacturers wiring diagrams and custom wiring diagram specific to the system, ECU manual, Start-up tune file, programs required I.E. as complete as I can make them. Every attempt is made to ensure that this kit is a great price/performance package for the DIY crowd.

The ITBs are from Australia (machined in Taiwan), the sensors/components can basically come from anywhere in the world, these days....even the Bosch ignitors are fabbed in China, while their clones are still made in Germany. The true source is often unknown, but should not matter as long as they are good, working parts.

While occasionally there are issues....The vast majority of installs have been successful, typically with questions asked, datalogs reviewed, a bit of tuning tips, etc.....and as most people that have worked with me know....I do my best to support the kits I offer and if there are questions related to the product, installation, documentation, they also know how to get in touch with me directly..
