Vivid Racing VR800 Garrett/Tial GT3076rs Turbo Kit Porsche 996TT 01-05

This kit can only be installed and built at Vivid Racing. Please contact us for shipping and service quotes.

The VR800 upgrade kit for the Porsche 996TT is a combination of proper fueling, air flow, and ECU Tuning. The GT3076rs turbocharger is much stronger then the previous VR750 kit using the GT2860rs. This kit requires a custom fuel system, larger throttle body and T plenum, custom Y Pipe, and fender mounted intakes over the intercoolers. Because the stock MAF sensor is limited to about 750 horsepower, we remove this system for a Ford MAF blow through design. This MAF allows us to tune much higher horsepower and control the appropriate timing and fuel mixtures for a clean powerband. All of the parts listed in the below options are required to achieve this power level. Other brands maybe considered for substitution, however we recommend discussing this with our Porsche specialists.

What makes this turbo kit superior to the competition is based on many factors. Cutting edge ECU tuning, modular design for upgrading power, high quality and well engineered parts, proper performance output tests in realistic conditions, and reliable street and track performance for vehicle longevity. Agency Power analyzed several companies turbo upgrade products. In this analysis we looked at package contents, product quality, performance gains, and pricing. To provide the ultimate Porsche 996TT turbo kit, we developed this package for a true bolt on performance gain with potential to increase based on customer requirements.

The VR800 turbo kit is designed to use Garrett GT3076RS ball bearing turbos. The turbos can be built with a .63a/r for faster spool or a .82a/r for more top end power. To increase torque, we developed the use of an external wastegate system. The Tial 44mm wastegates use band clamps with an external dump bypassing the stock exhaust system. Using an 1.0bar spring, the wastegates are very efficient for our use. The headers feature thick flanges to prevent warping. Using steel for the flanges prevents cracking due to the stainless material expanding under extreme temperatures. 10 gauge 304 stainless steel is used to build the header tubing. Low angle true merge collectors are put in place for proper exhaust flow producing optimal power gains. The collectors are also back purged when welded to finish off the high quality component. The headers are designed to bolt up to the stock block and mate with a Garrett T4 flange. For customers to retain their OEM replacement exhaust system, Agency Power uses an exhaust flange machined from 1018 steel which is then plated. The flange allows you to directly bolt on your exhaust system with no affects to the factory placement. The kit also includes the appropriate water lines, oil lines, and fittings to install your Garrett turbochargers.

This kit is a complete bolt on unit, however modifications to your factory oil tanks need to be made. These turbochargers are capable of 1000 horsepower in total. Any questions regarding installation, tuning, or about the products, please contact us.
