    Need fan clutch

    Oh, I didn't know that there's a difference compared to the later fan clutches (as these are rebuildable).

    Why don't you rebuild your fan clutch?

    240Z intake cooling delete

    @siteunseen Thank you, I've read some threads in the meantime. I think it could be deleted, however, during warm-up there would be no coolant flow through the head (thermostat closed). So the purpose of this line is, beside carb heating, to allow a little flow back to water pump. The only question is if the flow needs to be cut as soon as the engine is hot. I will keep it like this for a while and watch 🙂
  4. Hey guys, since I broke the intake manifold thermostat I bypassed the intake with a regular hose (red line). Would it be better to completely cap off the coolant flow by a plug at the thermostat housing and the 3-way connector at the engine passenger side? Thank you!

    L28 Stroker Build - I need your advice :-)

    I'm thinking more and more it is just a resonance during run down. I've heard that many BMW E30/E46 M3 owners experience a similar issue but there's no solution. I've switched to colder plugs, high octane gas, played around with ignition timing.. still rattling. My engine features completely different harmonics comparerd to stock (500g less weight per piston assembly!). Therefore, the engine mount stiffness might be not ideal now..

    L28 Stroker Build - I need your advice :-)

    So far I haven't found something loose. It's not only a noise but also a visible shaking - maybe a form of dieseling?

    L28 Stroker Build - I need your advice :-)

    Update! The engine is running 🙂 Got A/F ratio dialed in pretty well (using a wideband probe). Timing set to 16° BTDC initial, around 35° maximum mechanical advance. Only issues I'm still fighting with: When shutting down the engine, it rattles/shakes a little. Is this something unusual? I don't have another Datsun engine to compare, so I don't know if it is supposed to be like this. Besides that, the front nozzle of the SU carb sticks sometimes after the choke has been applied. Cables are greased, so are all pivot points. Should I try to bend something?

    Adjusting/recurving vacuum advance

    Thank you! I knew I've read it somewhere, but couldn't find it 🙂

    Adjusting/recurving vacuum advance

    Hey guys, is there a how-to recurve the Datsun vacuum advance mechanism? What are typical target values? I got a remanufactured Cardone ZX dizzy and would like to play with it a little bit. As far as I understood, there are two screws: - Inner screw for maximum advance (CCW for more maximum advance?) - outer screw for vacuum setpoint to start advance (CCW or CW for sooner start of vacuum advance?)

    Turn signal dash indicator reversed?!

    @Villeman All solved! 1. Rear lights not working: Ground points (behind licences plate light and above fuel tank) were missing 2. Turn signal indicator dash bulbs were reversed 😄 Took me a while, but it was an easy fix 🙂
  11. Hey guys, Finally, my late '71 Z is about to be finished. Only a few wiring issues are left - and I have no idea how to solve them. Current situation: I did the ZX alternator upgrade with harness plug instead of the old voltage regulator (seems to work fine). I did rebuild the combination switch (no issues during rebuild, I doubt I did something wrong). Issues: 1. Rear turn signals don't work 2. Front turn signals stay solid (Turn signal switch) 3. Dash turn signal indicators are reversed and solid (means left turn, right dash indicator turns on, left front turn light turns on) 4. Hazard switch turns on both front turn signals (flashing), no rears Fuses are fine, so are the bulbs. Could it all be low voltage related? Or is there a major issue? I remember when I first installed the charged (but weak) battery, the rear lights turned on barely visible. Thank you!

    WTB 280ZX distributor E12-80

    @EuroDat So I have to turn the inner adjustment pin clockwise in order to limit the vacuum advance travel, right?

    WTB 280ZX distributor E12-80

    @EuroDat: Did you ever try this? Does turning the screw clockwise increase or decrease the vacuum advance? I might have to do this as Cardone can't tell which advance they implemented. All years got the same parts number.

    L28 Stroker Build - I need your advice :-)

    So I decided to not tear the engine down again. NPR states in the piston ring manual:

    L28 Stroker Build - I need your advice :-)

    Piston and piston ring gap are totally independent. It all depends on ring material and block material as only the difference in thermal expansion is relevant. That's why I won't find a perfect answer, realised this today
