    Hello,

    Cat cam has solid lifters in his program. [:D] They I want to use. Now my next question. Do you know what Kind of chain tensioner (camshafts) the S2000 engine uses? Original one ? Has anyone pics ?
    Do you know the values of the S2000 camshafts ?
    I buy camshafts by a lokal engine builder which have follow values:
    Inlet: opening angle 288 °, valve lift 11,45 mm
    Outlet: opening angle 270 °, valve lift 11,00 mm

    What do you mean?

    There are various specs of S2000 engines... circuit, rally... and rules & evolutions …. its either 11 mm or 12 mm as maximum lift...
    some have bigger valves ( BTCC ) ... and C.R being 11/1 or 12/1 or 13/1.... and the cams are also different … for roll followers or finger followers….
    cam durations are inline with other high end engines … 290 degr upwards….

    Iam building a (sort of)replica of an Audi 80 STW.
    The STW is an old car and in that days Audi said it did 300BHP.. its more then maximum most Tuners/Engine-specialist say..

    I have a ABF on stock but when i read this forum, searching for info to retrofit TFSI Coilpacks on an ABF came to the FSI topic..
    The 80 has Longitudinal Engines, so a Audi A4 2.0FSI engine seems to be a nice 'modern' 2.0L engine as was in the early days.

    I don't want loads of HP, therefore i have a BYD/CDL engine on stock but thats not original.. (FSI isnt original too but is still is NA 2.0 16v)

    Whats an 'easy' HP-output to gain out of this Engine? 250? I want the high revs scream with itb's

    No "easy" or "budget" way yet for FSI builds. You need a bit of specialist skill to pull something like that off.

    As for reading about the STW engines and the 300+ bhp they achieved. Folks in European Hillclimb run engines with similar components, but their engine build budget is beyond that of most DIY.

    Rather than just modify an engine because you seen it or it looks different, it might be helpful to access what level of vehicle acceleration you are after + any other defining features, then based on that fact a powertrain can be chosen that achieves what you are after.

    I think if those specs were publicly floating about, every man and his dog will be making copies!

    Acceleration... its more the drivabillity on the track(and high revs).. getting an old engine becomes difficult.. discovered yesterday that the BYD/CDL engine has a different bolt-on pattern to the quattro-gearbox, the ABF 16v doesnt fit the same reason..

    Hello Guys my engine project is done. FSI head on 827er block. In the next weeks we will install it in the car. Thank you for your help.
    I still have a short question. Do you have the diameter or a picture of the exhaust port of a S2000 engine (Lehmann, ORECA, Spiess.....)

    Ok. Is there a spec ? 34 mm is the original diameter of the head in polished condition. That sounds good. The old 16V STW head has 43 mm diameter. I just have 37 mm. Then the outlet goes straight out. I think thats ok. This week I saw that Spiess ( Formula 3) used the TFSI head with 50 mm diameter. Thats why I asked you.

    Iirc 34,5 mm is the homologated size, and there is +/- 1 or 1,5 mm margin ... but its about 34,5 mm
    As there are std size ( 28 mm ) valves used that is large enough...given the area of the valves
    altough going a bit bigger, say 36 mm it gives a few cfm extra flow
    Exhaust porting is similar to the Audi STW head... altough its smaller

    Dont be fooled by the diameter of the primary pipes, the exhaust porting is as above
    Spiess used FSI and TFSI heads in F3
    Afaik TFSI head and steel bloc for the German F3 series ``Power engine `` which use a un-ported head and a larger air restrictor and can make upto 240 PS

    Sounds good. Very interesting information. The original exhaust port was smaller at the end than in the middle. With 36 /37 mm the Port goes straight outside. Now it looks perfekt. The Lehmann header has 40 mm diameter on the flange and on the primary pipes. Then the diameter is bigger. (45,4 mm inner diameter). I'm so excited about the power of the engine.....thank you.

    Skoda S2000 I think, but that would have become the R5 I guess.....not so clued up on all the rally variants.

    I back on the N/A TFSi trail at the moment, thinking to develop a clubman spec kit using the TFSi head on the ABF style block.....to suit most of the motorsport regs that require you to retain the original block. Seems to be a bit more kit available now for the N/A side and the std head will flow a good deal more than the std ABF head out of the box....I think lol.
