Since you all have been asking for more info regarding our B7 A4 Big Turbo Kit, I’ve done my best to compile some technical information obtained from our engineering department.
Some kit highlights:
A Garrett Turbo custom built to our specifications. We are one of the select few Garrett Turbo Kit Manufacturers, recognized officially by Garrett Turbo. This gives us direct access to their technical information and engineering services. We consulted Garrett to make this turbo with unique materials that are able to withstand the extreme exhaust gas temperatures the 2.0T engine develops.
A cast exhaust manifold designed and developed in house made of a state of the art high temperature resistant stainless steel.
Over the years, OEMs have been raising operating temps of their engines to achieve better efficiency and improve emissions. They have also begun using new materials that are able to deal with the added stress of these high temperatures, especially with diesel applications where exhaust temperatures can really elevate.
The rough prototype manifold installed on car:
We are using a modern 347+ stainless steel alloy (also knows as CF8C-Plus) that features the strength of more exotic alloys, but at a fraction of the cost. This material is truly a product of technological advancements made over the last few years in the exhaust manifold industry. See this .pdf link for a quick overview of this revolutionary material:

Here is a picture of our SLA model and production quality manifold:
A patent pending high pressure fuel pump designed and developed in house, and high flow fuel injectors. We have had several dozen current design pumps in long term use on several cars with zero issues. The pump will be released as a stand alone option in the next few weeks. Injectors were developed on our in house FSI injector test stand.
A 200 Cell HJS metal core catalytic converter, proprietary silicone turbo inlet and outlet hoses, and a mechanical diverter valve design.
Approximate power levels:
This is a dyno chart of the kit while still in prototype form. The power levels are close to the production numbers, but will be slightly detuned to run safely on stock internals.
The production kit will produce around 375 crank horse power and 330 crank torque on stock internals.
As you can see from some of the photos I posted, that besides the OEM cat, our kit does not remove any of the factory emissions equipment. It does not feature special programming tricks to bypass the OEM O2 sensors. It was developed with the mindset of delivering BIG Power without fooling the ECU into not throwing CELs, featuring cutting edge software from GIAC.
Time frame for release :
With a project such as this it’s difficult to nail down an exact time frame for release, but we are estimating the release date to be about 3 months from now due to lead times on some of the components that are made for us by subcontractors. Expect pricing to be around $5400.
I think that should cover most or all of the bases, but if there’s anything else you would like to know just ask and I will do my best to answer.
