Alternative INA Lifters????

[science 0]

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.

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?

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.

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.

Looks like these are more suited to higher revving race engines, almost twice the price of standard.

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.

It's a little more than I'd like to spend as I'm doing chains and tensioners too.

Yeah, it's not for me at the moment either!
