Genuine Garrett GT3076 turbo kit for 996TT. Compete bolt on kit which includes a pair of T3 flanged, 76mm GT ball bearing, water-cooled turbos. It has Tial V-band 44mm external wastegates. There are several housing A/Rs to choose from; smaller A/R allows faster spoolup and larger A/Rs allow better the flow at high rpms. These have the .63 housings which offer quickest spoolup.
Parts list:
-Pair of Garrett GT3076 turbos, 3" inlets, .63 A/R turbine housings, used but no street miles (bolted on for dyno testing and removed)
-Stainless steel true merge headers with 44mm external wastegate flanges and dump tubes
-Tial 44mm 12psi external wastegates, red anodized
-Stainless steel oil inlet lines (new)
-Complete coolant line kit (new)
-Exhaust adapters (allows use with any 996TT exhaust)
Appropriate fuel system modifictions and engine management (tuning) are required. For ultimate performance, the following upgrades are recommended: intake, exhaust, spark plugs, intercoolers, and clutch. Many other details and options are involved in such a build so if you are new to this please speak to your tuner or PM me for help.
These turbos are considered by many as the largest you can efficiently run on a stock 996TT/997TT engine. Output is typically limited to 700-850 crank HP for a stock engine depending on tuning and other upgrades. They are rated at over 1000HP for the pair so there is plenty of room to grow should you desire to push the envelope of tuning with race gas, or build a stronger motor.
PM or email me for references.

Dang Chris, your knowledge of my set up is impressive...however don't forget the second fuel pump and S car Go lower intake. Have you been feeding and watering your turbo tree again?
Where you going to install the API/Vivid kit? The quality is excellent.

I don't have enough info regarding tuning the 911 turbo engines, so excuse me if my question sound stupid. I have 997TT with full cargraphic exhaust system. I understand I need to get upgraded intercooler and ECU to run these turbo's is there anything else I need ?
You need upgraded intercoolers, ECU Tune, different intake piping, different water and oil line fittings. Switching to the Garrett setup is much different on a 997TT. I have done it and can provide you with the additional parts you will need if you get Chris' setup.
