Purchased new from 034 when I built the car, they only have about 1,500 miles on them so far, mostly dyno tuning miles. They are advertised as Ev14 850cc injectors, but they were flow rated at 3bar to 1000cc before the car was dyno tuned. http://www.034motorsport.com/fuel-i...s-850cc-bosch-ev14-fuel-injector-p-19844.html Car idles PERFECTLY with these. I am running E85 at 28psi and 450whp and it looks like they are starting to max out at 45psi fuel rail pressure, I would rather just upgrade to a larger injector than up the fuel rail pressure. paid $450 new, looking for $400. Also includes 4x adapters ($50) http://www.034motorsport.com/fuel-i...ter-bosch-jetronic-to-uscar-ev14-p-20128.html
