DISCLAIMER: I am NOT an expert on all the information found in this post & thread. It has been put together by various contributors as a central source to answer the most basic of questions for current and prospective TSI VW/Audi owners.
Right to the point: YES, there are 2 types of motors in the MKV body style VW cars as well as 2008+ Audi models. (confirmed that MKVI models have the same 2.0 TSI motor)
FSI: found in 2006 and up to 2008 models, available in automatic, 6 SPD manual, and DSG.
TSI: found in late 2008.5 and up models, available in automatic, 6 SPD manual, and DSG.
Do I have an FSI or a TSI? POP YOUR HOOD AND READ THE BADGE!!
Do I have a CBFA or CCTA? Look at you factory airbox; if the airbox has a 2nd hose coming out of the front of the airbox then your car has the CBFA version of the airbox as shown here:
NOTE: the U.S. Spec TSI is NOT the 1.4L Turbo and Supercharged engine that is found in the UK; rather it is second generation, if you will, of the FSI. A 2L 16V direct injection engine - with an IHI Turbo.TSI motor (regardless of CBFA or CCTA):
Displacement: 121 cu in (1984 cm3)
Maximum Power: 200 hp (147 kW) at 5100 - 6000 rpm
Maximum Torque: 206 lb ft (280 Nm) at 1700 - 5000 rpm
Number of Valves Per Cylinder: 4
Bore: 3.2 in (82.5 mm) & Stroke: 3.7 in (92.8 mm)
Compression Ratio: 9.6 : 1
Firing Order: 1-3-4-2
Engine Weight: 317 lb (144 kg)
Engine Management: Bosch MED 17.5
Fuel Grade: 95/91 RON
Exhaust Emission Standard: ULEV (CCTA) - SULEV (CBFA)
Some major differences from the FSI to TSI include:
-- chain timing vs belt as seen in the FSI
-- different fuel/engine management system
-- components in the intake system (as defined above)
-- oil filter and oil dipstick relocated
-- improved PCV system (proved to be problematic in the FSI)
-- compression ratio lowered to 9.6:1
-- more balanced cam shafts in the center of the block on both sides
-- down pipe
-- better emissions (by U.S. standards and regulation)
-- more 02 sensors on exhaust system

There are several hardware differences between the different versions. The main changes between the US versions is simply Emissions. US vs ROW also has emissions changes and some other hardware changes for more "headroom" for the higher output "b" version.
CCTA = US Hardware - 200 HP
CBFA = US Hardware, High Emissions - 200 HP
CCZA = ROW Hardware, 200 HP
CCZB = ROW Hardware, 210 HP
US MK5/MK6 2.0 TSI Engine
CCT and CBF denote the engine's mechanical structure. IE, secondary injection (CBF) vs non secondary injection (CCT). A, the 4th letter, denotes the power output for the calibration, ie both rated in the us for 207ft-lb/200hp.
ROW MK6 and A3 2.0 TSI Engines
CCZA - A3
CCZB - MK6CCZ denotes the european mechanical structure. A denotes the 200HP calibration. B denotes the 210HP calibration.originally posted by xgtiride
...The fuel system is now run off of a new lobe of its own to reduce wear, which was a problem with some of the earlier 2.0t engines (from the tech's mouth). It is now also run off of the exhaust cam and no longer the intake cam. The tech noted that the injectors must overcome the combustion pressure of the engine to even force fuel directly, causing them to have operation pressures upwards of 1400 psi.....the intake runners have a plate splitting them into two pathways. In the intake manifold exists individual butterfly valve like air flow splitters that direct the airflow into only half of the intake runners while cruising or coasting, thus increasing gas mileage. The airflow is directed into both paths when the engine is under load to increase air flow and power. Other notes: The intake is not part of the engine cover, and the sound pipe can easily be removed...Official TSI SPEC SHEET from VW(courtesy of Arin Ahnell @ APR)Recall/Warranty/TSB Info from VW(courtesy of Arin Ahnell @ APR)There is still carbon buildup in the intake manifold, even though it's not as bad compared to the FSI. Here is a DIY carbon cleaning with removal of the intake manifold.A few of the TSI owners have reported failing water pumpsA few of the TSI owners have reported of failing HPFPs
With every passing day, there are more and more modifications being introduced for the TSI. Revo, APR, GIAC, and Unitronic all have software/flash capability for these motors. Other basic mods:
DIY Guide for installing a K04 on a TSI
Boost tapping points: There are plenty of boost tap kits to make stuff work for our cars that worked on FSI (boost gauges, Forge DV's). Some of the more popular ones are made by BSH, AWE, and 42DD.
Intakes: have been released by companies such as APR (Carbonio Stage 1/Stage2), AWE (CCB intake), NA Motorsports (VF Engineering), BSH (Stage1/2), Neuspeed (p-flo), and even ABD racing.
Downpipes: FSI applications can be modified to fit TSI cars depending on what engine code you are (CBFA vs CCTA). The mating flanges are slightly different (will require modification) as there is an extra 02 sensor in the stock CBFA setup. (consult your preferred dealer as to what software would clear a downpipe CEL). TSI specific Downpipes are available from various companies, too. Catbacks systems remain universal from FSI to TSI.
Suspension: overall components remain the same. Maybe a few aesthetic parts here and there like an extra rubber mount or bushing. 2008.5+ GTI's also appear to have a lower suspension from the factory compared to 2006-2007 models, but only by a little. Front and Rear sway bars are the same.
Intercoolers: (All of the available FSI intercoolers will properly mount up to the TSI engine)
BSH, APR, Eurojet, and Audi S3 (yes, it's compatible with some self fabrication). Discharge or turbo outlet pipes are available by AWE, Neuspeed, BSH,
BSH Vent to Atmosphere Race can
BSH Recirculation Catch Can
Forge (the Forge Catchcan is more of a PCV upgrade than just a catch can; it reroutes all of the PCV gases through one line)

I will update this as more information becomes available....everyone feel free to post more info to be included...i will add it to the original post and give you credit if you wish, just delete your post after i acknowledge it so this thread doesn't become 234324 pages long.
