JD. It's basically a stock 93 z28 lt1 With #24 injectors with a chip. To raise the fuel pressure with boost it closes off the return line with the blue disc on the d/s valve cover. At the moment I'm basically 6-7 psi and have seen the gauge hit 10 psi from time to time. I have no idea what the total timing is at the moment but I am running an old crane fireball ignition that retards timing as the boost goes up. The car runs great at 180 all day and I would would like to modernize the electronics to open up some tuning options but I'm fine with how it performs now
yes, i see its a 93 f body motor, i can tell by the accessory mount, p/s reservoir and fuel line placement. but i also see a b body water pump. anyways, i'm curious what mounting plate did you use for the vortech? is it for a tune port? or did you just modify the f body lt1 plate?
i also like the S shaped VORTECH air inlet to the intake manifold.
Got some stuff done. Again, please ignore the rats nest wiring as I will get to that soon enough.
I cut part of the Z28 PCM mounting bracket so it would sit flat on the fender well.
Here it is mounted next to the battery. A nut was used as a spacer to level it under one of the attachments.
Just below the PCM I mounted a ground terminal and a batt + terminal. the factory Z28 battery cables are being used since they have nice size aux cables attached in addition to the main cables. You see these aux cables running to the terminals I mounted.
Obviously, ground wires for various things will gather at the ground terminal. For the batt + leads, I'll be using the Z28 ones including the fusible links for protection on the heavy circuits.
Here's the mounting location of the Z28 relay box. First pic is the base plate that the box snaps into. Second pic is relay box snapped in. Third pic is the location of the junction box that will conceal all the various soldered splices once all the wiring is trimmed down to final length.
