kona41 Posted February 12, 2016 Share Posted February 12, 2016 So I have been quietly following this for quite some time now. Just wanted to say congrats on this being in the car! So will you be heading to the Dyno after it is running and broken in? Video and details! Amazing Quote Link to comment Share on other sites More sharing options...
TheCrazySwede Posted February 16, 2016 Author Share Posted February 16, 2016 So I have been quietly following this for quite some time now. Just wanted to say congrats on this being in the car! So will you be heading to the Dyno after it is running and broken in? Video and details! Amazing Thanks bud! It's been a long time coming, that's for sure! For now, I'm just playing around with different tunes on the carbs to see what runs best. The setup that it came with was too lean A. What the Carbs came with / B. What I'm trying out 40DCOE Weber Carburetors A. Choke: 28 / Mains: 115 / Air: 170 / Emulsion: F11 / Idle: 45F9 B. Choke: 34 / Mains: 145 / Air: 175 / Emulsion: F11 / Idle: 55F9 I also got some air horns and those mesh lookin' air filters. I'll post some videos once I get her up and running well!

Keepn it OG Posted August 23, 2016 Share Posted August 23, 2016 Beautiful build and congratulations with a sick set Up! I too have the same taste in nostalgia. I plan on doing the STD set up after im done with my suspension and brake upgrades. I love the throaty exhaust note. Where dis you purchase the exhaust from?

kona41 Posted August 28, 2016 Share Posted August 28, 2016 Oh man. That revs quick! That's awesome! Abarth exhaust sounds killer. So how does the motor feel in the car? How is low end? Quote Link to comment Share on other sites More sharing options...
jenks Posted August 29, 2016 Share Posted August 29, 2016 Following this with a lot of interest. I put in the STR stage III last year with DCOE40s, and finally got it on the dyno this year. Pretty disappointing results (pretty sure it's something I did and not the builder), so I'd like to see what another similar build will do!

jenks Posted September 2, 2016 Share Posted September 2, 2016 156 at the wheels. I don't want to hijack a thread here, so I'll be posting all the info and specs in the next few days to see what kind of feedback is out there. Quote Link to comment Share on other sites More sharing options...

Hopefully you have a good header on it too. Quote Link to comment Share on other sites More sharing options...
TheCrazySwede Posted December 8, 2016 Author Share Posted December 8, 2016 Beautiful build and congratulations with a sick set Up! I too have the same taste in nostalgia. I plan on doing the STD set up after im done with my suspension and brake upgrades. I love the throaty exhaust note. Where dis you purchase the exhaust from? Thanks bud! Eiji is very knowledgable and really knows his stuff. I bought the exhaust from Abarth Exhausts: http://www.abarth-exhausts.com/datsun/ If you scroll down, you'll actually find my exhaust as an 'alternative' version of the stock exhaust setup. Owner decided to offer it as a special order since I requested to have a much bigger inlet. I bought two of them. One is on the car. The other is on display in the house Oh man. That revs quick! That's awesome! Abarth exhaust sounds killer. So how does the motor feel in the car? How is low end? Motor is amazing! Feels like going from a plastic knife to a Katana. It really is that sharp! Low-End torque is great, but she really prefers to be past the 4k marker. I honestly thought my speedometer was busted for a while there, until I went up against my friend's WS6 Firebird. The real power is up there, but due to how fast it gets there, I'm not complaining! Really is a blast to drive. Currently having lots of electrical issues, though! 156 at the wheels. I don't want to hijack a thread here, so I'll be posting all the info and specs in the next few days to see what kind of feedback is out there. Yeah, that cannot be right. My stock L28 got around 140 to the wheels. As i mentioned above, I went against my friend's WS6 Firebird and my Z flies past it. No way your motor should be making that little. Check your tune!

TheCrazySwede Posted December 8, 2016 Author Share Posted December 8, 2016 Having some more wonderful electrical issues :/ To try and attempt diagnosing my electrical issues, I've reverted most of the electrics to stock: New Externally regulated alternator New voltage regulator New battery cables (x2) New OEM Fusible links With key set to "ON" - Alternator reads 12.20v Fusible Links read 12.20v Battery reads 12.23v As soon as I turn on my headlights, the volt gauge in the car drops to 0. Running lights, parking lights and dome light won't come on. Same effect occurs if I try to turn on the fan, use wipers or hazard lights. Headlights come on and turn signals work. One of the brake lights also causes the "short" issue, but with that particular light disconnected the issue no longer occurs. Swapping bulbs with one that does work still causes same issue in that particular light. Still, Alternator reads 12.20v Fusible Links read 12.20v Battery reads 12.23v I checked the ground wire from negative battery - good. I checked my fusebox - good. When I first made the swap, the alternator was pushing out 17v before I swapped it. It may have fried something along the way, but I don't know what. Today, however, after getting a brand new battery, voltage popped above 16v again. Dome lights come on. Headlights come on, but I can see my fusible link (Alt/Battery one) is burning up. Any ideas? Thanks! Quote Link to comment Share on other sites More sharing options...
NewZed Posted December 8, 2016 Share Posted December 8, 2016 Today, however, after getting a brand new battery, voltage popped above 16v again. Dome lights come on. Headlights come on, but I can see my fusible link (Alt/Battery one) is burning up. Any ideas? Thanks! Voltage "popped up" while the engine is running, right? You are using a good meter? Sounds like your voltage regulator Sense wire is not sensing. You should focus on the "burning up" fusible link. Fusible links are there for when things aren't right. So, obviously, something is shorted, probably, on that circuit. Check the wiring at the starter for starters. And use your meter to be sure things aren't shorted, before connecting the battery.

rturbo 930 Posted December 8, 2016 Share Posted December 8, 2016 (edited) So what kind of power did it end up making? And so I have this right, this motor has an 89mm bore, 83mm stroke, and standard valves? Did he weld up and reshape your combustion chambers or no? Where does it make peak power? How is it around town at ~3k rpm or less? Edited December 8, 2016 by rturbo 930 Quote Link to comment Share on other sites More sharing options...
NewZed Posted December 8, 2016 Share Posted December 8, 2016 It made 17 volts before he swapped the alternator. Now it makes 16+. Quote Link to comment Share on other sites More sharing options...

Yup, with engine running. Not running shows the standard 12.x. Meter is good and tested. I might actually still be hitting 17v - I didn't linger long enough to get an accurate reading. As I was getting a reading, I noticed that the link was burning up again so I turned the car off. But I did see "16.x" show up on the screen before I put the meter down. How should I go about checking it for shorts without the battery connected? Thanks for the help! EDIT: You can see a little smoke coming from where the fusible link is right at the end of the video Edited December 8, 2016 by TheCrazySwede Quote Link to comment Share on other sites More sharing options...
fraz Posted December 8, 2016 Share Posted December 8, 2016 Try disconnecting your alternator completely. It may have a big short in it. If not, disconnect everything wherever you can and measure the battery voltage. Then add things slowly until you get a drain. Quote Link to comment Share on other sites More sharing options...
CobaltFire Posted December 8, 2016 Share Posted December 8, 2016 What I'm seeing after a quick look at the schematic for a Z (I'm new to these but work on electronics for a living) is a couple things. First, the indication that turning on the lights works but your voltage goes to 0. That indicates that wherever your voltmeter is wired to is seeing ground. I need to know where that tap is. Second issue is that voltage spike while running. I'm betting that wherever the sense wire goes is shorted to ground. That would cause it to push the alternator high. A few possibilities from looking at the short issue for a few minutes: bad light switch, bad tail lamp (if removing the bulb fixes the issue that's it), bad dimmer. I'm going to bet it's two seperate problems. Quote Link to comment Share on other sites More sharing options...
