Spent the past two morning swapping a fresh manifold, injectors, and then all the swap wiring. Did I need two days? No. But sunny cold weather taking my time, and doing a clean install was more important
Poking around doing research, people claim the 5.7 injectors are fine. I just kept the 6.4 ones and installed them with the manifold, and i have to say she actually idles smoother..maybe my high mileage made my original ones a little dirty and rough, but getting her street tuned later this week to adapt to the injectors. All good so far
I was surprised to see the heads this dirty, put new gaskets about 10k miles ago and i don’t remember the runners being that filthy...92K miles builds up i guess. Spent the better part of 2 hours cleaning the runners with some brake cleaner on a rag and a vaccuum, while sealing up the ports with paper towels
Manifold drops in nice and easy, catch can setup is a tad wonky until some new lines comes in. MSD sits nicely I used an existing hole on the fender wall, took a 8-32 rivnut and a button head screw, drilled a few more to match for the relay.
Followed factory harness to keep the look clean, used info all found here on the forum. Did not need the cirkit boss, however if you dont already have an assortment of wire, terminal ends, and butt connectors then i guess their product comes more “complete” but having some at my disposal, the leash electronics relay bus worked great and for only $20 vs $90 for the cirkit boss
All in all, a GREAT mod, instant gains she pulls all the way to redline now instead of falling on its face after 4500 rpm... definitely noticeable torque down low too.
