Hello all, I entered the 300zx project club by simply buying an engine (TT) with the intent to eventually put it into a rolling shell. It was going to be as stock as I could make it just to keep things simple. I have since recently bought a 1989 Z32 TT 2+2, a bit sooner than I was expecting. It needs a lot of love to bring it back to life. Because it needs a bit of work it got me thinking about things that I could do while I have the engine out. This has turned into needing to do a heap of rust repairs and got me further thinking about what I can do while I have stripped the entire car and giving it a re-spray..... To that end, I had two major things I wanted to achieve. 1) Modernise the engine bay 2) Modernise the interior/HMI aspect of the car i.e. sensors/cameras/digital guage cluster/infotainment system etc. Both of these things I have little to no experience in and I'm hoping there are people here that can help steer me in the right direction. I'm not after bolt on fixes where possible, I would like everythign to be as integrated and deliberate as possible where I can. To modernise the engine bay, I was looking at a new ECU. So far I have looked at the Haltech Nexus R3/R5 and a new generic harness or Elite 2500 plus Plug + Play harness adaptor. Does anyone have any experience with these or other options? I want to be able to reduce the sensors, vacuum lines etc that can be modernised using more contemporary solutions. I also would love to add drive-by-wire and all the other functions that go along with a new ECU. For those who know a bit about this, is it worth a whole new harness or is it just as good to use the existing one? What things can I get after to take full advantage of a new ECU? I assume to some degree what happens with the Engine ECU will have flow on effects with the second part of my plan, as there would be lots of inputs to any updated dash clusters/infotainment systems etc? Has anyone successfully brought a Z32 cabin into the future (now) yet? Does it require its own ECU on a new CAN BUS? I'm after : Integrated parking sensors Integrated reverse camera Digital gauge cluster (think modern BMW/mercedes/audi instrument cluster) - customisable digital display that integrates GPS GPS that's integrated into cluster Upgraded steering wheel controls? Integrated HUD, displays GPS/NAV info I am fully aware this is a bit of a pipe dream but there are a lot of new technologies like Android Auto that are starting to make this stuff a bit more achievable/affordable. Even if I can't achieve all of this now I want to be set up for it when things come available in the future. Happy to hear anyones experience or advice with any of it. Cheers!
