  1. So what I thought was going to take me a couple days took me 5 or 6. Lol. My welding has not improved by not using it it. Amazing. Lol. Here is me using my back purging cap (made of a slice of the muffler outlet which slides over actual pipe nicely, then capped with sheet metal and a fitting threaded in) and welding a few pieces to the old flex pipe. It was 3” as I always planned on upgrading. All welded up and hit with scotchbrite. The thing that took me the longest, was how to hang the system. I went through many types of hangers and spent the most time doing this. I have the pipe with such tight tolerances to surrounding pieces I needed the whole system to be very secure. I started by hanging the whole system with New car OEM style hangers. They work great but you really need to stretch them horizontally to make your system secure. By doing this it’s also hard to line everything up exactly where you want. So the rear muffler hangs off these. This worked for the rear, but wasn’t working with the pipe going through the front differential/control arm mount. So I used these cheap J hook style ones and made a bracket to the crossmember. Have no clue what those threaded holes were for in the bottom but I guess I’m not going back now. Lol. The thing is rock solid now. So now my welds just need to hold up. As you can see they aren’t that pretty. Lol. working on the tips tomorrow. They are going to be a little complex. Hopefully it all works out as planned.
  2. Decided to build a new exhaust. Old setup was a 2.5” “Premium Exhaust” from MSA, modified with a vibrant ultra quiet resonator and a magnaflow muffler. Since I’m now turbocharged, 3.0” was in the plans. I also wanted to add a catalytic converter as I’m tired of smelling like fuel every time I drive the car. So the cat will replace the vibrant resonator. So I spent an hour or two rubbing all pipes and muffler with SOS and WD40, followed by Acetone. Proceeded to spend the next 6 hours today making hanger brackets, and getting the muffler in the exact right spot. No pictures of that yet, but I do have the pipes! There will be a lot of pie cutting as well to get the perfect fit. I plan on taking my time on this one but should be done by next week.

    I don’t know which one it was, but an EGR version of the 280z intake.

    Well I had some slight differences in my plugs, so I just moved mine from 4 to 3.7. I’ll let ya know if it changes.
  5. Since Hybridz is a bit more of an engineering site vs a photo gallery, I made this alignment system after installing the coil overs. string alignment, and I used a cube inclinometer for camber. (iPhone actually works pretty good too). The first time I did a string alignment I used jackstands to mount the string. Everytime You jacked the car up to make an adjustment you had to realign the strings and ensure it was square. With the mounting points of the string attached to the car, you can can make multiple adjustments without worrying. Was a fun project.
  6. Photos hide many of the imperfections, but it’s certainly has many many battle scars. One day a full tear down will happen. But one must have everything setup before they make it all very pretty.
  7. I just ran down and took a few more shots. Most recently I discovered the 10g WR wire which runs through the car was fried and cracked in many places. Due to age and definitely helped out by my 140amp CSS alternator. I ran new wiring where required, worked out a couple bugs and ran a 4g wire through a 100amp breaker to the starter. My hope is this take the load off the original 10g wire that runs through the cabin. I also got a hold of a stock 280z voltmeter and replaced my original ammeter. Photos attached. Also attached photo of my interior complete with Porsche Boxster seats reupholstered in black leather (they were $200 torn up beige specials). I redid them with a more classic 240z/911 style. I never ended up adding the heated seats but they are power. You can also see my ECU/Fuse assembly under the passenger side. Aluminum glovebox. Holds my AFR gauge when tuning, and switches for manual operation of fans, pumps, antennae etc. also included photo of my fuel system at the rear. The whole assembly comes out with 1 (or is it 2?) bolts. All fixed to a fixture using rubber radiator mounts.
  8. I’ve almost started a thread on here so many times, and it’s unfortunate I haven’t as the car has been through so many iterations. But better late then never!

Just hoping this thread can perhaps sway some traffic to come back over. I’m still playing with wastegate springs, but have seen 10psi with very conservative tuning. I won’t be increasing over that until I source some larger injectors. 10psi, 80duty cycle and only 5200 RPM (this cam likes to go to 7k). Chickenman gave me a beautiful base tune and has been working his magic, with the help of me fiddling and screwing things up in between. Once I get proper wastegate springs in, I will be headed to the dyno for some high power tuning. The car is running like a champ other then some heat soak issues. It’s been many years. Engine wise the car has been through a few versions. L24 w/e31 head and SUs L28 w/ N47 head and SUs L28 w/P90 and SUs Then introduced MS2 and LS2 ignition coils Then eventually EFI Then finally over to the Haltech and added Turbocharger Ill try and keep this thread updated with changes. Next up is most likely strut bar fabrication, and possible reworking of intercooler piping. Possible manifold fabrication. For now I just want to drive it. It’s been 6 years and now it’s reliable and time to enjoy.

    Very interesting about the dwell. What made you come up with that idea?
  10. From the look at those photos, Id be getting a timing light pretty quick! Your right in regards to that being 180 degrees out. I can’t remember if that piece is reversible on the distributor itself or not? Perhaps the plug wires are not in the correct position and they did that to try and correct it?
  11. Can you get someone to check the timing quickly while it’s running?
  12. Awesome! Are you able to fill us in what rubber bushing was used in replacement?
  13. My wife bought me a retro sound radio a few years ago. Requires trimming your own faceplate but it’s as correct as one could ever ask for. bluetooth, MP3 whatever. Honestly it never get turned on, but looks great. Light green writing really sets it apart.
  14. I once came across an issue where I wasn’t getting enough engagement. It ended up being when I had disassembled the clutch slave (for fun), the piston was pushed too far in and the fluid inlet was not positioned correctly. I forget the exact configuration, but it still moved but would not get the entire range of motion. Fluid was getting sent to a wrong oriface. It took 3 very experienced minds to figure out the issue (well 2, as one of them was me). Ha.
