Basic tsi info/acronyms/faq

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!! :thumbup:

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
CCTA
CBFA
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.

...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...

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:

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,

Catch Cans:
BSH Vent to Atmosphere Race can
BSH Recirculation Catch Can
42D Design
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)

Popular abbreviations and acronyms associated with VW/AUDI:

EASY WAY TO TELL IF YOUR CAR IS CCTA OR CBFA
Pop open your hood and inspect your 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.
The CBFA version also has a 3rd sensor (a 2nd o2 sensor) on the DP that is used for emissions purposes.


Different revisions of the TSI motor:

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

CCZB = ROW Hardware, 210 HP

The MKV and MKVI Share the SAME TSI motor:

Q: How strong are the rods in the TSI motor?
A: For the FSI motor the industry standard for how strong the rods are considered to be 350 ft/lbs of torque. Nobody has yet puplicly reported bending any rods in the TSI motor, but the TSI rods are in fact stronger.

Im not saying the rods can or cannot withstand any amount of power, just meerly sharing pix of the rods with the community (Thanks to [email protected]):







Nobody has reported any bent rods yet as the TSI motor has only been around for about 3 years now and Turbo upgrades are just now picking up steam. Only time will tell the strength of the new rods

Oil Change in a TSI Motor:
Quote, originally posted by VeeRrrSick »

The good news is that you don't need to touch these covers on a TSI for an oil change. I did my first one at the first 1,000 mile mark just to train myself (and to see if there was any metallic content).
The drain plug is accessible (points toward the rear), and the process is very painless.
1. Put the warm car up on ramps or jack stands
2. Remove the drain plug (19mm socket)
3. Remove the oil cap to speed draining
4. Once the flow slows significantly, loosen your oil filter slowly until you hear the flow increase again. Let it sit partly unscrewed and drain. (There's a breech pin that'll open if you haven't read about that--it's great.)
5. When the flow slows down significantly, unscrew the filter the remainder of the way by hand and pick the filter straight up. There shouldn't be any mess.
6. Lube and install the new filter.
7. Replace drain plug (no new crush washer is necessary from what I've read... the washer's permanent on the drain plug).
8. Fill 'er up. 5 qts. Start with 4.5, run it to get oil into the filter, and check. Add as needed.Enjoy the relatively painless process! I had a blast... and plan to do changes between dealer maintenance just for the peace of mind... and the relaxation.

If you want to mount up a DP that is made for the FSI/ TSI CCTA engine you will have to modify the flange to fit for the CBFA (cut out the 2 parts of the flange that are colored with the charpie):



MORE Info on the difference between the FSI & TSI (CCTA and CBFA) from 42D Design:
Taken from the 42D Design webpage:

Yes. Our downpipe has been designed to fit both FSI and TSI motors. The downpipe flange has been machined to fit both turbochargers. Some TSI motors (CBFA) have 3 oxygen sensors instead of 2. To accommodate this configuration an extra oxygen sensor bung has been added.​

FSI and early TSI motors are equipped with two oxygen sensors. The first sensor is located before the first catalytic converter directly after the downpipe flange. The second is located after the second catalytic converter.​

CFBA and later TSI motors are equipped with three oxygen sensors. The first sensor is located on the turbo. The second is located before the second catalytic converter. The third is located after the second catalytic converter.​

If installing on a FSI or early TSI motor, plug the second oxygen sensor bung on our downpipe.​

If installing on a CFBA or later TSI motor, plug the first hole on our downpipe.
The extra bung can be used for a wideband gauge and sensor at any time.​

PZEV is just a term/label for the "Partial Zero Emissions Vehicle" that they put on the car
So then you either have the CCTA or the CFBA engine code....we just need to figure out which ones go with what type of engine (non PZEV vs. PZEV), lol

i think you're right...people may have a PZEV vehicle based on what state they bought the car in...maybe PZEV was just an 08 thing...and the 09's are SULEV (revamped PZEV)?

We'll just never know....there's like NO info on this car (specifically the motor) at all
Last time I checked the VW site they still had the '08 GTI on there & were still showing the FSI motor in it, LOL
But yeah....certain states have to have the PZEV cars (like California & some of the northeast states).....so that's why I was wondering if the CCTA/CFBA meant the difference between PZEV & non-PZEV

Did it say that on the window sticker??

I'm almost 99.9% positive when I was at the dealer on Tuesday & he pulled my VIN it said CCTA for the motor code (doesn't say anything on the sticker sheet)
So I think the CBFA is the PZEV version & CCTA is the non-PZEV version

Re: BASIC TSI INFO/ACRONYMS/FAQ (ShippensburgGTi)

Alrighty so as Im sure you guys are aware of (those guys that own 2009s that is) the 2009 models come with a "Carefree Maintenance" program. Today I had setup to meet for the Courtesy Vehicle Check, and for some reason I thought that they would change the oil. I guess when I called in and made an appointment I stated that I wanted an oil change or whatever.
Anyways, once the "Courtesy Vehicle Check" was done I was handed an $80 bill for doing an oil change

Do yourselves a favor and change your own oil before you do your Courtesy Vehicle Check and just have them inspect all the fluids. I wasn't expecting a bill.
That's what I get for not looking up something in advance

Re: BASIC TSI INFO/ACRONYMS/FAQ (ShippensburgGTi)

Thought I would add to this thread as I recently was able to check out an 09 GTI engine being rebuilt at my local VW dealership... As well as I am a new 09 GTI owner
.
Quick story: This GTI was over-revved to 8900 rpms and some valves and lifters were destroyed. I am assuming the owner accidentally miss shifted.
The first thing that the tech, who was a VW enthusiast himself, told me was that the entire valve train and head can be removed assembled to access the engine internals. Thus the advantage of this is that if you were to replace piston rings or need to access the engine internals, you can do so with out disturbing the valve train. He noted that he removed the head cover and the cam shafts were just sitting there, as the bearings are built into the case.
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.
Fuel mileage tech: 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.
If anyone has questions, just ask. I probably know the answer, I just can't think of anything else new about the engine at this moment to post.

Correct. However I was still kind of leary putting 10k on a brand new motor without an oil change..... I misunderstood what the free 6k maintenance inspection was comprised of and I ended up spendin some extra cash.

hmmm they charged you for your 5k oil change on an 09vw, i was just at the dealership yesterday and i asked about the free service on the 09 GLI i bought and he said the oil needs to be changed at the first 5k then 10k after that but didnt say if they would charge me I'll have to check that out. and i talked to a tech and he said they updated and changed the water pathways on the new TSI. thought i would add that little bit of info.
