That's right Dave, VW didn't bother because there's not much point in winding up a (standard)VR6 too high. The V6 Audi lump of the period used them and I think the limiter is set at 7200rpm. If anyone is interested in a set I've found a UK supplier which would work out to >£120 delivered for a set of 12. Only catch is they only supply in batches of 8 tappets.

After trawling the American and German VR6 forums, it seems many people have had success with the lighter weight lifters from the 16v and g60 engine; VW 050109309H INA 420004310 Weight 50g/54g As opposed to the original VR6; VW 034109309AD INA 420002210 Weight 80g/86g Google search "vr6 leichten hydrostossel" for more info.

I had the same moment before I took it all apart. It became obvious when I actually saw it.

The VR6 head is flat, so skimming it will not change the volume of the combustion chamber. Like a book on top of a pint glass, the thickness of the book will not change the volume in the glass. Changing the thickness of gaskets /spacers or skimming the block will change the volume and therefore the compression ratio.

It seems some Cosworth YB engine owners have used VW's (034109309AD) tappets as a cheaper alternative. But they are inferior to the Cosworth engine labyrinth design tappet. http://www.ina.de/content.ina.de/en/branches/automotive/engine_systems/product_range/mot3200/mot3210/mot3211/mot3211.jsp Cosworth INA part no. 420004810 TSTHL type (hydraulic bucket tappet labyrinth design) 64,5 gramm? Volkswagen INA part no. 420002210 TSTH type (hydraulic bucket tappet) 81 gramm? INA Hydraulic tappet catalogue; http://www.schaeffler.com/remotemedien/media/_shared_media/08_media_library/01_publications/automotiveaftermarket/catalogue/downloads_2/INA_valve_train_components_pc.pdf I'm not suggesting using these as the specification may be different, with potentially disastrous results. But the INA Cosworth tappets are now cheaper and easily available.

I'm after a set as well. It seems the INA one's aren't available through ebay. The alternatives seem to be; Kolbenschmidt Febi Trucktec Camtec Topran I'm guessing the Kolbenschmidt one's would be the next best alternative to INA?

On the Vr6, the combustion chamber is not in the head, so it won't change the compression ratio. I think the way to tell is to measure the head height but I don't have the original factory value, only the 139.5mm minimum.

I didn't, that's cool.

If the info in the TDI club link below is right, G13 with mix ok. http://65.110.12.166/showthread.php?p=4095897

All I can find is a minimum height of 139.5mm. I'm guessing beyond this it affects the timing? What is the standard head height?

Sounds good! I'm London east but not very regular.

I think yor are a great mood! Can you lend me 201 teuro?

Yeah, I'm in need of a new loom. Could also do with the Vag com lead if no one else wants it. Pm'd with address. Cheers

Would relay appreciate the headlight loom and the obd2 adapter please!

Pm'd

I'll take them please!

Whoa your right, missed that one! (Edits own post with shame)

Lupo Gti? I have 2x non Gti O/S arms with aftermarket aero blades on mine, work great just don't look as nice.

Hi Mike, are these the stainless steel version?

Are parts available for collection? Is so, where are you?

Ill take these please John! Will pm with details...

Is the Bosch 3 bar fuel regulator new? If so I'll take it please.

Kev, Would you say the 57mm piston (passat?) version of the calliper is worth doing over the 54mm golf 288 setup?

Thanks!

I'm looking for a set of these, but for a vr, do you know how they differ?
