ATP makes available, a 500HP capable turbo hardware kit for the FWD 2.0T FSI, MKV VW Golf/GTI/Jetta and Audi A3 featuring a host of components such as exhaust manifold flanged for GT/T3 series, Garrett GT3071R dual ball bearing turbo with GT V-band exhaust housing outlet, Tial 44mm wastegate with V-band connections, 3" all stainless V-band downpipe and rear transition pipe to stock exhaust, wastegate reroute tube and v-band connections in/out, all stainless coolant and oil lines and fittings, 3" inlet pipe kit with 3" MAF housing along with intermediate inlet pipe with integrated breather ported connection, diverter valve reroute, intermediate charge pipe outlet kit to meet with ATP FMIC pipe.
VW's latest generation 4 cylinder turbo engine, the 2.0T, has an inherently awesome VE (volumetric efficiency) curve. In fact, it is so great that it is just cause for all new, from the ground up testing in search for the proper matching turbo.
Once we peeled away the improperly sized (by design by VW) factory spec K03 from the engine, did we then began to see the true potential of the new engine. The increased displacement of the 2.0L engine (from 1.8L on 1.8T) and the greatly improved flow potential of the new cylinder head design resets the playing field for the power making game.
After much testing with 2.0T engine in the last couple of years, we can honestly say that "it's no 1.8T". The power and response of this new platform requires a whole new turbo strategy.
Why such a "large" turbo as a GT3071R? An efficient turbo to match an efficient engine! It's a great match! You could go smaller as usual but you'll choke up the engine in the higher revs!
After countless test sessions, all the data shows the GT3071R allows the 2.0T operate very close to its natural efficiency curve (to develop HP as the revs continue to climb to redline). Not only that, but it's able to do it without sacrificing low end drivability. This allows us to run the full scale 60mm turbine wheel on the GT3071R coupled with the highly efficient GT/T3 VB exhaust housing (which ensures proper engine breathing at the mid to high RPM range to make excellent HP) to gain peak efficiency AND STILL have the ideal low end power bandband for everyday street use. That's right, with this new engine, you can have your cake and eat it too! Big power and no lag. You will NOT have to resort to the smaller turbine wheels with smaller exhaust housings just to get the turbo to spool up quicker, but at the expense of higher backpressure numbers and higher EGT temps which subsequently kills peak power to the point where you will have to turn your boost levels much higher than necessary to make good power. By using an efficient and well matched unit like the GT3071R to do the job, you can make the desired power more safely, reliably, and best of all, effortless (with less boost).
Note: You are recommended to source a fueling/tuning solution to compliment this turbo kit. We found that the stock fuel system maxes out at crank 350HP on 91 octane, which translates to about 15-16 psi max on this turbo kit. This means you can take a typical 1 bar chip that runs a bit on the rich side on the stock turbo and make very good power with just the bolt-on hardware. Just make sure the program doesn't hit boost cut when you hit 15-16 psi peak boost. You can run directly off the wastegate pressure and have a ball with this amount of power until a bigger injector fueling solution becomes available. Always watch your air/fuel mixture to make sure you don't go lean when turning up the boost with any boost control device.
