pressure converters: pierburg vs kayser

ColonelSanders · 06-30-2017, 11:43 AM

I'm getting into my vacuum system and so far suspect one of the converters. Has anyone had experience with the kayser aftermarket converter? Normally I'd just go for the best, but at a $60 difference for a fairly simple part I'm less sure.

Pretty sure keyser is an OEM supplier to BMW. You may want to pm Yozh as he may have more experience with the different brands

Kaiser is an OEM supplier.

hi did anyone changed the pressure converters on both turbos 335d? there is a new holder as well. bmw wanted 400 bucks to do that

There is one pressure converter for a turbo switchover and another for wastegate. No more for 335d. There a few switchover valves as well. One for compressor bypass, one for EGR cooler and engine mounts. If you are in Europe then you will have a pressure converter for the EGR and I think a switchover valve for the swirlflaps.

Yozh · 07-20-2017, 04:50 PM

Yes. Did at home. Not difficult but there are a few important points to consider.

JOHNNYBRAVO1 · 07-20-2017, 08:48 PM

I did also, along with everything on it
