BBI Core Acceptance Policy

Originally these injectors have a flow rate of 61.8 l/h @ a pressure of 100bar.
Ours flow at a rate of 76.2 l/h/100bar --> 24% increase compared to stock
For model years 2004.5-2007 we utilize a 124° spray angle

These injectors are capable of up to 700rwhp. We've found NO reason to run injectors smaller than Stage 1. Injection quantity reduction is a simple adjustment, thanks to the Smarty. Decrease fuel quantity to satisfy the needs of your current set up, or crank it up to 700 RWHP.

Note on Stage 2-4 for these years

Because of the inappropriate nozzle spray angle we do not offer a higher flow nozzle for these types of engines. Any larger than the Stage 1, our quality control standards could not be met. In addition to the Stage 1 nozzles the complete injector setup can be changed, which provides better engine response and high performance at high rpms. Changing to 2003 Pistons paves the way to use our MY03 Nozzles, with their ideal spray angle. With the 2003 style pistons, there are no Limits on Power or reliability.

To our reman line: Those injectors are delivered within the same functional tolerances as new BBI injectors and come with the same warranty. There is a core charge on them! All reman injectors are disassembled, cleaned and completely new adjusted. All our reman injectors get a new hard chrome coated valve set and a new DLC coated nozzle. Also all older injectors will be upgraded to the newer better guidance/puck design to have a better more centric connection with less friction between the valve piston and the nozzle needle. Which gets them a better low pressure functionality and will make them more stable over lifetime. All other injector parts are measured, investigated and tested and if necessary they will be exchanged to new parts also. Again our BBI reman injectors come with the same tolerances as new BBI´s, so every part internally has to function perfectly to do so. They are also tested with the same test program as new injectors and you get a test certificate with complete injection mappings. So you can see the function of every injector in over 500 test points per injector. But if money is not an issue we still recommend to buy new injectors as their expected lifetime is always higher as with reman injectors. Nobody can forecast for example how long it will take until an injector body cracks as it is impossible to see/measure/check how much pressure oscillations it has already seen in the past or what kind of pressure it was used at.

BBi Testimonials


Big Bang Injection was formed at the request of accomplished engine software tuning guru Marco , of MADS Electronics, SMARTY fame. After extensive testing and research of existing aftermarket performance injector options, none were found to be built to an acceptable standard, when utilized in an extreme performance application. Marco clearly saw a need in the aftermarket, for a top shelf injector with consistencies, tolerances and calibrations, as good as and better than OEM quality.

Unable to locate a suitable existing product, Marco sought out, the best of the best, leaders in the field of Common Rail Fuel Injection Technology. Two years later, after thousands of dynamometer runs, and tens of thousands of street driven miles, we are READY. Big Bang Injection has come to market with every intention to dominate. We did not come here to "play", nor do we intend to "compete". We are here, ready to dominate the aftermarket performance Common Rail Injector Industry. Big Bang Injection has raised the bar, so HIGH, it's now out of the reach of the competition.

That was and is our intention. Set the bar SO high, that everyone else must jump, to even imagine touching the new industry standards set by BBI, which all other players must now be measured. See for yourself, that we are not just blowing smoke. We are sure you will enjoy our products as much as we do!

Common rail electronically controlled injectors are extremely complicated. They are built at the limits of modern manufacturing technology. These injectors have higher durability requirements than any other part of a modern diesel engine. Bosch has designed its injectors to make billions of injection cycles over their lifetime. Therefore they have responded to a multitude of challenges such as: cavitation erosion, tribological stress, particle erosion, functional behavior and so on. They really are a masterpiece of European engineering.

Every adjustment parameter, every single piece (even the smallest) inside the injector, has its own function to meet all these challenges.

We believe we are the first company modifying injectors, that really understands how the injector works. Achieving the maximum output in performance, without harming the long term , separates our products from others.We are the only supplier capable of improving the nozzles, as well as the internals of the injector, essential for getting maximum power on racing applications.
