Hi guys, I have *no* experience with the new style engines of VAG. But this picture is a Lehmann engine from a S2000 Audi A4 og 2005-2007 design. My best bet is that this is a 2.0 engine for revving and a 20V header. Any input on what you see in this picture?
I guess you are right from what I get on Google. Perhaps the car in question is setup with the OEM 2.0 FSI as basis for some classification (homologation). But besides that, would there be any reason for Lehmann to run a "blocked out" 16V instead of the 20V header if not needing the high pressure FSI injection? And why not utilize the FSI rather than "conventional" injectors?
As vw_singh said it's a FSi block and head , but they have opted to not run the FSi injection system and instead use a more conventional injection method i.e. port injection.
Thanks! I am only slightly puzzled over all this, as it seems there are some Audi A4 ran in STCC with the same chassis (B7) that utilizes the 20V head. I don't know this with accurate information, but the owner of two Audi Sport A4 supertourers is looking into purchasing a third "play thing".
Its a FSI 16V - 2.0 L in S2000 spec 85 mm x 88 mm bore / stroke Wet sump / 500 gram rods / 350 gram pistons / 13+ kg crank / FW 4.0 kg Rev limit is 8500 rpm by S2000 rules Power 280 300 HP / TQ 260 270 Nm ( depending on spec ) Early engines started as 20V ( with large port head ) Later the 16V FSI head was homologated on a 06A block At a later stage they used FSI Block & Head ( 2006 - 2007 ? ) The exhaust flange is universal for 20V and 16V FSI FSI / Direct injection need very short short injection times , the higher the revs the narrower the window and with long Cam durations you need to avoid to spray on the valves during opening ( 100+ Bar fuel pressure) For N.A its more compromise than it brings
I wish this forum had a Thank You-button. So in essence, Audis for Supertouring has been based on the 85 x 88,1mm configuration, but evolved into utilization of the more "off the shelf" 2.0 FSI 16V as a basis? Interesting to see the evolution of the supertouring engines at Audi.
Probably not using FSI because it doesn't do what it says! VW couldn't really get it to work properly so it's mostly a badge now. Source: Work at stealership.
I'll get more detail from someone at work but the long and short is it was meant to deliver diesel like economy and greater power delivery but only works correctly if you drive like you're an old man. It's not that it doesn't "work," it's that it doesn't have any of the benefits it should and recent software updates stopped trying.
I am getting really confused. Owner of two A4 typ B5 STW cars, going to purchase one STCC FSI typ B7 car, states "they are all 20V". Doesn't make sense!
FSI are 4v p/cylinder iirc. Pre-FSI 20v 4 cyl is 5v p/cylinder unless some were 5 valve engines until a change over. I've got some self study guides I can try and get answers from.
I wasn't aware of this, I thought all 2.0 130hp engines was 16V. 1.8 20V 125hp of Audi A4 "B5" 2.0 20V 130hp of Audi A4 "B6" 2.0 16V FSI 150hp of Audi A4 "B6/7"
Finally found relevant engine picture from Google. Here is the 2.0 130hp non-FSI 20V engine in an Audi A4 "B6".
Just got picture of a genuine Lehmann header with injector holes under the inlet ports. Anyone knows if they ran FSI 16V aswell in S2000?
Anyone know anything about tuning the ALT? Are high compression pistons a option? Which rods fit? Are the valves, springs, etc same as a 1.8T?
