Sorry I don't check this forum as much as I used to. My buddy is a vendor for Pure, so I ordered through him. It took a while to get it back - prob 7-8 weeks or so. But not too long.

How does the 800 compare to the 850 in perf?
Is there a major difference in build? (I'm worried about reliability)
Is the 850 more available than the 800?
Will it work on my b58 engine for my 440xi 2018?

I own a 21 Zupra (6 port) with a pure 850. The 850 is slightly laggier than 800, but I honestly couldn't tell much difference when I was as passenger in a pure 800 Supra. The turbine side is identical, but the compressor is a bit bigger with 850
