    May be completely wrong, but you can run it on 87 octane?

    TSI - stands for turbo charged (+superchareged in a few models)
    FSI - no turbo/no supercharger

    Obviously, chipping naturally aspirated engine gives less gain than chippping turbo charged.

    COMPLETELY WRONG...do you even research the info you post?

    Both FSI and TSI Motors have turbos. The ACTUAL difference is FSI motors are Belt Driven while TSI motors are chain driven.


    and as all turbo motors go...both will required premium fuel.

    stole this from another thread

    CBFA/CCTA has:
    -timing chain, no more timing belt
    - balance shafts in the block
    - pulley/gear/crank multi-piece
    - 4 lobe cam with roller follower
    - Fuel pump runs off the exhaust cam
    - Different layout of the cams in the head
    - different tensioner setup at the back of the head
    - the new Engine management system med12.5. Much more advanced control strategies and some new surfaces that make calibration so much more powerful!
    - Fueling is much, much better for lot's of reasons. More pressure for one, new pump, roller follower and some other stuff...
    - New air intake setup, no more engine cover/airbox combo
    - oil filter and oil dipstick relocated
    - improved PCV system (we'll see about that)
    - Compression ratio lowered to 9.6:1
    this discussed the TSI and the FTSI in the CC and the A4, but this shows the difference between the new motor and the old one.

    credit goes to Dark_Helmet he schooled me in the other thread

    I was told the same thing. However, it was explained to me that I could use regular for "city/around town driving" and the computer would recognize it. For long distance driving, always use premium. I just said "oki doki" and let it pass. I got to tell you though, when the gas prices went crazy, I used regular on several occassions for around town driving.

    lol...probably true. Regardless of what your dealer says...doesn't anyone believe in car karma. Feed it 87..it might go ..., but feed it 91+ and it will go

    Sorry, but you're off base also.

    Jancha is actually correct. Prior to the new 2.0T's with the TSI badging, there is an earlier TSI engine, 1.4L with both a turbocharger & supercharger.

    The owner's manual says you can run it on regular.

    91 AKI or higher is recommended. The keyword is recommended. Recommended doesn't explicitly mean mandatory.

    The fsi is really just a tsi, but the first letter is turned upside down to save on badging costs. Just to f*ck with people.

    Wow. It's a little hot in here.

    So the TSI definitely sounds like the better motor, if it's got chain-driven camshafts and oil pump. I never did understand why the hell the 1.8t has a timing belt if the engine will destroy itself when the belt snaps.

    yea I guess I was referring to the relevant motors, that is...the ones you would actually see in a Passat...

    the 1.4 TSI is available in the Passat. Of course, not in the US.

    1.6 (No tsi, no Fsi) - 75kw/148nm
    1.6 FSI - 85kw/155nm
    2.0 FSI - 110kw/200nm
    1.8 TSI - 117kw/250nm (TURBO). <-- replacement for 2.0Fsi
    2.0 Turbo FSI - 147kw/280nm
    3.2 Fsi V6 Fsi - 184Kw/330nm

    and then there are 3.2v6 and R36

    also, in Turkey they have 1.4 Tsi which features BOTH Turbo AND Supercharger 110kw and 240nm (here at my country they offer this engine for Tiguan only)

    so, FSI and TSI alone does not tell you weather engine is turbo charged or no, you gotta look at the engine that it comes with.

    now tell me i'm still wrong

    I think we chimed in because your first statement:
    TSI - stands for turbo charged (+superchareged in a few models)
    FSI - no turbo/no supercharger
    is very non descriptive, and if you read it, sounds incorrect.

    now tell me i'm still wrong
    and in that post you say 2.0 turbo FSI which contradicts what you said earlier, so im still going to say your earlier post is wrong
