Product description: The TC Turbos TC900XT turbokit is a complete kit for any customer that want to unlock the full potental of hies 2.5 TFSI TT RS, RS3 or RS Q3. The TC900XT turbokit comes in various stages that are listed below. Depending on previous modifications on your car you may need further supporting mods, or you can continue using already installed parts. In any way please read our power guide below carefully and make sure, you have the correct supporting mods for your power goals.The TC Turbos TC900XT is based on an brand new original DAZA / DNWA 2.5 TFSI Borg Warner stock frame turbocharger and always comes with heat shield. The TC 900XT is a result of more than 2 years development that had the main focus on reliability and daily usability as well as on the maximum power output. The turbo itself uses our latest technology of 9 blade exhaust turbine wheel and the 10 blade highflow compressor wheel. The turbo uses the stock actuator, which makes it comfortable in terms of softwaretuning. It can be used even with low grade pumps fuels.  The response of the TC900XT is similar to a standard turbocharger. The turbo is able to generate 1100NM at 4000 rp/m. Throttle response is stock level, although peak power can be up to 530 hp over stock. The TC900XT thus plays in a performance class of many fullframe turbo kits, but is clearly superior in terms of response, durability and suitability for everyday use.Turbokit configurations:Kit 1 is the basic Kit, that consists of: TC900XT turbo (new), TC Turbos 4" 100mm turboinlet,  5" 125mm intake system inclusive filter, 2,75" 70mm charge pipe, 4" 100mm Downpipe inclusice adapter to stock buttom decatpipes, 2 x boost pressure sensors.Kit 2 contains above plus: Spot Serie intercooler, 3,15" 80mm charge pipe inclusive turbosmart race port blowoff, billet throttlebody elbow, billet mashined high volume intake manifold.Kit 3 contains above plus:4" 100mm valved ECE homologated catback (race) exhaust system (downpipe straight into catback, no Y-piece), Twin power fuel pump 1100HP version, oversized fuel rail, secondary fuel line.Kit 4 contains above plus:ECC & HP remote flashing dongle for ECU & TCU tune as well as highspeed logging function.  The following power numbers are possible with the 900XT and the appropriate fuels as well as supporting modificatio93 ron (US) / 98 octane (EU) = 600 hpFront intercooler (HP Sport Series), TC Turbos inlet 4", HP 2,75" chargepipe, Intake system (min. 3,5"), Downpipe (min 3,5")95 ron (US) / 100 octane (EU) = 680 hpFront intercooler (HP Sport series), TC Turbos inlet 4", 4" intake system, HP 2,75" chargepipe, Downpipe (min. 3,5”), Engine reinforcement (Engine Pack 2), 1000ccm injectors, Mechanical blow-off valve (HP blow-off pipe), Pressure sensors 2 xNGK R7 series spark plugs98 ron (US) / 102 octane (EU) = 780 hpFront intercooler (HP RACE series), TC Turbos inlet 4", Intake system 5", Downpipe 4", Engine reinforcement (Engine Pack 2)1000cc injectors, Mechanical blow-off valve (HP blow-off pipe), NGK R7 series spark plugs, 3,5" Exhaust system from the catalytic converter, Boost pressure pipe on the passenger side, Pressure sensors 4 bar, HP 1100NM clutchkitE85 / XE85 = 930 hpFront intercooler (HP Race Series), TC Turbos turbo inlet 4" , Intake system 5", Downpipe 4", Engine reinforcement (Ethanol Engine Pack), 1000ccm injectors, Mechanical blow-off valve (HP blow-off pipe), NGK R7 series spark plugs, 4" Exhaust system from the catalytic converter, Boost pressure pipe on the passenger side, Pressure sensors 4 bar, Intake manifold increased volume, 3,14" throttlebody elbow, Clutch kit (HP 1100NM), HP fuelrail kit, HP Twin low pressure fuel pump We can also supply the right software for every fuel.
