Buying Beisan VANOS, What Else Do I Need?

[ac427]

Yeah I did them back in 2016 because that seemed to be the best thing to do at the time. I think next time I'll go back to the S54 ones, there seems to be some evidence out there that response times are adversely affected.

True, the internet knowledge collective does evolve over time. Even garage Vanos experts, who fix Vanos issues for a living have changed opinions relatively recently too.

I purchased new S54 diaphragm springs when i had my Vanos unit swapped over. I'll take responsiveness over an imperceptible noise level reduction.

I wouldn’t mind if there was some real data to back up the S62 springs, perhaps there was on the old forum, but as it stands it seems more like one of those things that everyone does because everyone does it, I will also go back to the S54 part.

Did anyone use the VAC Motorsports Vanos Hub upgrade?

I don't believe there ever was - I researched a lot on the old forum back when I did mine. It was simply recommended by Beisan, but they didn't present any actual evidence to back it up other than saying “the S54 springs weaken over time”. Which look, they may well do, but going forward I'll probably just make them a maintenance item rather than using the S62 ones.
