Anyone running a Euro motor upgrade their fuel pump?

[Kovs]

I'm running a Euro S50B30 with Gruppe N cams and a 3.2 crank. My concern is that the stock E30 fuel pumps aren't reliable enough to consistently deliver enough fuel during hard track driving. Any thoughts? Can the BimmerWorld E36 fuel starvation kit be made to work with the E30?

Also, does anyone sell a wideband O2 sensor?

My goal is to always have the engine running rich enough to prevent detonation.

Thanks in advance.

as long as the stock fuel pump is in good working order you will be ok.

I upgraded my fuel pump to 255 LPH Walbro. This should be enough for that motor. Another option is to use the Euro E36 M3 fuel pump. But even with these high flow pumps, some folks in UK still reported some starvation during cornering and they doubt it's a fuel pump problem.

I'm using the Walbro as well, so far it's been working great, pretty loud though.
