What psi/bar fuel pump will i need to fuel my R6 throttle bodies. Its on a zetec running MS.

cheers guys

I have Kawasaki ZZR1100 throttle bodies on my car using a Bosche high pressure pump rated a 3Bar , the fuel pressure regulator is the one that came with the TBs

Most injectors are calibrated at 3 bar so in the absence of information regarding your MS map I'd go with that. If you haven't mapped it yet I'd still go with 3 bar. It leaves scope for increasing if you find your duty cycles are a bit high and you can equally decrease if needs be to improve resolution.
