Trying to see if you guys have suggestions with fuel pump on my S50 swap. I was on the track last weekend and looks like I have fuel starvation on high RPM, roughly around 6500-6700 rpm I have fuel starvation. Let me know how could I upgrade to better fuel pump.

When my stock pump died I threw in a Walbro 255, dropped right in and will definitely flow as much as you need. There is a lot written about fueling issues in the track/autox subforum that you'll probably want to check out as well, such as fuel starvation during right hand turns below a certain fuel level, etc.88 325is - S52 powered
