Wrapping up this renesis rebuild today! We tore down this one 3 years ago with spun bearings and devastation of the original engine. Owner sourced a good core and here we are a little while laterπŸ˜‰. Built with future boost in mind, 12.5mm studs, upgraded apex seals from Jose Jvm PerfDepot, and a dash of port work, this one ready to go home.

Cameron Giertz FC we finished up recently with a haltech elite 1500 install, injectors and IGN1A coils. Engine was rebuilt last year by us with a half bridge port and strength mods for future turbo pans.

FD dropped off by a tow truck recently.. Engine ran outta oil :/ suspect rear main leak?.. Hate to see it.. It's the worst kinda failure with metal contamination everywhere.. all bearings spun, internal parts making contact with other parts they are not supposed too :(.. Anyone have an e shaft, rotors and stationary gears, oil cooler and lines for sale? Possibly whole another REW short block? πŸ€”

Solid 513rwhp..Fuel pressure issues resolved, installed a 465lph fuel pump. Finally we can get a decent safe tune in on Zac Se7enS beast FD. 93 octane with a sprinkle 🀌 of AEM Electronics water/meth injection, Haltech , 21-22 psi on the turbo. Engine we built/ ported around 5 years ago here at Phalanx still strong as can be! Now to address the brakes πŸ˜…. Thanks Zak for pretty much giving us free reign to do what we wanted on his awesome FD. 🀝
