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. The old school Italian made racing beat exhaust sounds incredible, with those 13b braps it's just πŸ€ŒπŸ‘Œ

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€”

13B-REW came in with the dreaded low compression from warped apex seals on a another shops "tune". We rebuilt it with some extra strengthing mods new seals and she's back to running smooth as silk 🀌.. We also replaced the stock crusty engine harness with a Rywire 13b engine/ ignition harness. Were going to get it back to the owner on our low boost break in tune first. Then back for more hp's and pounds per square inch on the turbo after break in. We'll get some dyno videos shortly stay with us!

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. 🀝
