Anyone have some success stories for speaker sizes that fit well in the stock holes in a 77? Looks like there might be depth limitations . I also imagine no speaker lines up as far as bolt pattern , but maybe get lucky. This Reno car I’m doing has a vintage Sansui stereo that I’m going to try and utilize , but the speakers are shot. Don’t even need anything great , just something that fits.

A/C for 240z 1 2 3

Hi, I'm currently looking for a 240z with working A/C. My understanding is that A/C was a dealer installed option. My question is: Is it better to wait out for a 240z with working A/C, or find a clean Z and install an A/C? Also, if if I find a clean Z without A/C, where can I locate an A/C kit, and how much would the installation cost? Thanks, Jacob

Just when I thought I was in the finish straight on my '71 240, another puzzlement pops up. Before installing the windshield wiper motor, I did a bench test. Works OK. Installed the motor, and drive assembly, then turned on the wiper switch, and everything seems OK, with the splined drive stubs rotating just fine at both speeds. Install the wiper arms and blades, and they twitch perhaps a quarter inch, then stall. Turn off and on, and absolutely nothing. Take off the arms and the cowl; everything looks OK. Put the cowl back on and the drive stubs again rotate on command, but put the wiper arms and blades back on, and same thing - a quarter-inch twitch, then nothing.…

so I got my turn signals to work, I was wondering if it's lighting up correctly. I thought only the bottom section(next to the reverse light) would flash not the upper and lower part. Also it looks like I have a ground issue when my headlights and hazards are on? If so where is the ground? Thanks! right turn signal headlights off.mov Hazards headlights on.mov

I have a 73 240z and the ignition switch is toast. Can pull the key in any position and it gets stuck in the on position nearly every time. Anyway, I ordered a replacement but my with has 2 wires, red/blue stripe that attach to a small switch located in the main switch. I did a search and it seems these go to the "key in buzzer"? I want to confirm this and get input on if I should remove it from the old and try to install it in the new switch or is there alternate wiring suggested.

Hey Folks, I have read extensively about putting a 280zx distributor into 240z and that seems like a great upgrade. However, 260z and 280z both had electronic ignition distributors and I was wondering why people don't swap those into the 240z instead/also. The reason I am asking is because I can easily get rebuilt 260z and 280z distributors and they bolt right in with no differences to the dizzy mount as far as I can tell. However the 280zx distributor has a different mounting block and I can't seem to find any of those to purchase, I don't think they are included in the rebuilt Cardone distributors. I feel like this answer should be out there, but I have bee…

Last saturday i decided to install a pertronix ignitor 1761 module with 1.5 coil asides from replacing the 4 year old battery with a 12 volt 600 amp brand new battery. Even though i have cleaned and tightened all the female and male connectors at the coil, i am still experiencing some needle fluttering when the car is at idle. Is this normal or could it be fixed? Do i need to widen the gap between the ignitor sensor and the magnet Installed in the distributor? 20180729_144008.mp4

I have had an ongoing problem with my tach bouncing when I shift. It goes up about 1500 to 2000 rpms when I shift. Doesn't seem to bounce while in gear, or at idle. I searched for this topic but didn't see anything. Any thoughts?

Working to get a car back on the road after a 20 year nap. Tank has been cleaned and reinstalled. Working to replace the electric fuel pump. However, power dose not seem to be making it back to the fuel pump. A kill switch was placed under the dash and that seems to work, power goes in and comes out of the switch and to the harness connector in the console under the radio, but no power is making it to the connector at the fuel pump. There are two wires at the pump with bullet connectors, one is ground (black wire) and I has been tested for continuity, the other will not read. I figure that there is a break some where between the console and the back of the car. Ho…

My 1974 260z haa uad some difficulty starting. I read up and found the engine has a reset button so I tried this and it would finally turn over, after i had replaced starter and ignition switch, but every wire in the ignition system got so hot they started to smoke... I'm not going to pretend es and I have any idea what's happening. The car has an electrical points upgrade, and an ignition coil from a 240. Currently not messing with it for fear of burning all my wires completely. Please help!

Starting off by saying hello.. First post but have read a lot. I recently purchased a gem 1973 240z. The car is nothing short of amazing. Super clean original, working dealer installed air, no rust, has been repainted.. a really lucky find and as fate had it, found just a few miles from my home.. I'm building it to a daily. Will be sure to post some pictures. My problem. I have installed pertronix ignition with a 1.5ohm coil. I have wired it precisely to the John Hull wiring diagram with the BR wired in.. My tach no longer functions. It worked perfectly before the swap. All wiring appears to be factory with the exception on the red and black pertronix. Wha…
