blodi Posted July 30, 2019 Author Share #457 Posted July 30, 2019 Just realized I also need the 280ZX dizzy mount. Do I also need the adjustment plate? Anyone have these? Link to comment Share on other sites More sharing options...
siteunseen Posted July 30, 2019 Share #458 Posted July 30, 2019 Someone bought one from here not long ago. https://zcarsource.com/distributor-mounting-block Link to comment Share on other sites More sharing options...
blodi Posted July 30, 2019 Author Share #459 Posted July 30, 2019 Found a source for both parts and ordered them up today. I did get the car started with the new dizzy last night and adjusted the timing, but realized I couldn't tighten it down with the 240 mount/plate. 2 Link to comment Share on other sites More sharing options...
blodi Posted August 5, 2019 Author Share #460 Posted August 5, 2019 I installed the new dizzy and got the timing all set. Took it for a spin Friday afternoon and it ran great and pulled hard! But, once you got over about 3.5K, the tach would start bouncing all over the place. So I stopped for gas and reconnected the resistor in an attempt to fix that. Well, I started the car and it died after about 10 seconds. Long story short, I fried the ignition module. Had to get a ride from a friend back home and got the old dizzy and installed it and got the car home. So, I ordered a new ignition module and I guess I'll have to look for a 280z tach to install.

blodi Posted January 4, 2020 Author Share #461 Posted January 4, 2020 5 months later.... I finally got around to trying to install the 280z tach here while it’s winter. Quickly realized I can’t remove my stock tach as my car has a full dash cap on it and blocks the tach from coming out. I don’t want to force anything and break the cap or tach. So...anyone know of a aftermarket dizzy that will work with a stock 240z tach? I haven’t searched yet. Also...anyone need a 280z tach or rebuilt dizzy? ?

siteunseen Posted January 4, 2020 Share #462 Posted January 4, 2020 Zx dizzy with stock tach is what I have on my '72. No problems at all. Link to comment Share on other sites More sharing options...

Sorry, I meant that I had a 280zx dizzy that I was installing. I did try it with my 240 tach and it's fine until about 3K and then will bounce like crazy.

siteunseen Posted January 4, 2020 Share #464 Posted January 4, 2020 I followed the diagram on "blue's tech tips zx distributor on a z". Google that and go to the next to last drawing I think. It had to be easy, mine works great. Link to comment Share on other sites More sharing options...
blodi Posted January 5, 2020 Author Share #465 Posted January 5, 2020 This is what I used... Car ran great. But the tach was just bouncy when I got on it at all. 1 Link to comment Share on other sites More sharing options...
jonbill Posted January 5, 2020 Share #466 Posted January 5, 2020 I used a zx distributor with my stock 74 tachometer. Lots and lots of people have zx distributor with stock tachometers and no problems I think. I'm inclined to suggest try a different stock tacho before a different distributor. Maybe there's a problem with your tacho. Link to comment Share on other sites More sharing options...
blodi Posted January 5, 2020 Author Share #467 Posted January 5, 2020 Yeah, the problem is I can't get my tach out because of my full dash cap blocking it in. Sounds like some people have issues with the swap and some don't : https://forums.hybridz.org/topic/122001-240z-tach-issues-with-280zx-distributor/ Im wondering if there is any dizzy out there that will work with a 240z tach without issue...other than a stock 240z dizzy. Aftermarket? Link to comment Share on other sites More sharing options...
