Late last night I finished rewiring the injectors I bought from odistiger, replacing the cracked old connectors with fresh new ones, soldering them in, and heat-shrinking the connections. I also took a closer look at the wiring harness, and have to wonder what the hell Nissan was thinking. There are butt-connected wires for the + side of all the injectors, and it’s just a messy hack-job that’s a sorry excuse for wiring under the factory heatshrink. I’m going to have to clean it up a bit, but there’s really only so much that I can actually fix in there. The wiring harness is simple and straightforward though, so I may just rewire it from scratch using the stock end connectors.
I excitedly started attaching my injectors to the intake manifold, hopeful that I’d get to hear the engine turn on its own power. Each injector has a mounting adapter and two screws that hold it onto the intake manifold, and ensure a tight connection. You can clearly see properly mounted fuel injectors on my intake manifold in the picture to the right. On my intake manifold, one of the screws had been torn out of the intake manifold at some point, ripping the threads out with it. I filled the hole with jbweld and will re-tap it as soon as I get my hands on a tap kit. Until then, I only have 5 injectors and can’t hear the engine fire.
I’ll be sure to get some more pictures of the final setup once the jbweld hardens.
Making some progress and it’s coming right along! What are you going to use for tune?
I’m going to try the stock l28et ecu, but I doubt that it’ll be able to adapt to the larger compressor and increased fuel supply, so I expect ill end up with megasquirt.
