I saw some flow matched 52# EV14's on the hfv6 forums that operate at 3bar rail pressure and have six ports that are being promoted for the LY7. I figure I have 100k miles on my engine, and might as well upgrade my injectors when I replace my spark plugs and install the Volant and Ice-lator and RX catch can. I think these upgrades with a good upper engine cleaning will really give my CTS a new lease on life. Anyone else replace their injectors with anything other than OEM? I havent gotten any answers on my other topic about this, so I will ask again here, has anyone ported/polished their gen1 LY7 heads? But yeah, the injectors are the main focus of this thread. Any help would be appreciated.
