Due to a vicious accident I had to put my 240z motor/tranny into a 260z to revive it. As you can imagine this created a whole new world of electric problems. I would like to switch to the single wire GM alternator conversion. Have any of you done this or know how and could give instructions?

HELP!!! Here is what happened, I filled up my gas tank and started driving around and gas started spitting a steady streem out of the front carb float boal vent pipe???! So I figured that the float needle wasn't shutting off the gas. I took it apart and fixed it or should i say tried to fix it. I put it back together and the exact same thing happened. What is going on? Its a new needle I addjusted it today! the butterfly valve is working im lost. Help!!!!

well i was driving my z it was running good and then i stopped it for my family christmas party after the party i go back out to leave and try to turn it on and it wont start... it turns over but no go. i have spark most absolutely in every plug and i have this compression 120,130,130,130,130,90... so im thinking the fuel must be the problem cuz its been running good...so i tried jumping it and stuff and then went out the next morning to try stuff and my buddy helped me look at it and we found the intake just totally flooded, there was gas in my air filter...so i dunno im thinking the FI works but maybe the valves arent opening or something anyway if anyone has had a si…

Anti-backfire valve & backfiring

I am debating on whether or not to leave the anti-backfire valve on the manifold of my 260Z. The throttle linkage has accomodation for the valve. What do I do with this part of the linkage if I decide to remove the valve? Also, does this valve really do what it is supposed to do? I am stripping off all the smog stuff, but if this valve actually reduces or eliminates backfire on decelleration, I don't mind keeping it. Thanks in advance

Has anyone here ever installed the Turbo exhaust sys. from MSA? Was it difficult to do it yourself? Did you need any other parts that wasn't mentioned in the desription in MSA's catalog?

Starting Below 20 degrees?

I am having a heck of a time trying to get my 260z started. It came from down South so the cold totally killed the battery that was in it. I got a brand new battery and it started up with little problem, I let it run the idle smoothed out, everything was cool so I turned it off. I tried starting it up again shortly after and it fired right to life. The next day it was increasingly difficult to start, the engine just cranks, but wont turn over. After about 10-15 minutes trying to start it with and without the jump assist from my battery charger I got frustrated and gave up. Stubornly I went back out to the garage about an hour later and it started the on the second try. Y…

From inside the car..there is a wire on the left side top of the engine that goes from near one of the injectors to the left side of the engine compartment...this is on the opposite side of the car from the battery...the wire appears to be flat looks kinda like a snake skin..this wire is severly damaged due to what looks like either fire or it just shorted out....does anyone know what the wire might be...or what its for...the car is running fine with the exception of being just a little rough in 4th gear...starts ok and every thing else...but something is wrong with the wire.. Thanks Mike...77 Z Columbia SC

Ok here is what happened. Everyday about 5-10 minutes before I leave work I go out and start my car so it will be warmed up enough to pull out into traffic. Last night it got down to 26 degrees here and today was really cold, so I decided to go out 15 minutes early. I cranked it, put the club on, locked it and went back inside to finish work. When I came out 15 minutes later there was steam pouring from underneath the front of the car. I hopped in and saw that the thermostat was pegged over to the right. I turned it off. It smelled pretty bad. I popped the hood and found that the fan had somehow wedged itself against the bottom of the top lip of the radiator. It had sat …

Thats how I feel, ok 72 240z , it run great for a bit then starts to spit and sputter then dies, I can get it warmed up and drive it around the block a few times it seems to be about 20 minutes of running before it quits , rebuilt carbs , new vacume hoses ,new fuel pump and filter, 280zx electronic dizzy , timed correctly , I ran the car from a gas tank<portable> for a bit and it did the same thing died while from an alternate source, so I was think it wasn't the gas tank, and if you wait a few minutes like 15-20 then it will fire up and run run for a few then do the same thing , after it dies when you try and start it again it runs like the points are bad , spitti…

No Spark, No Start

While waiting to have the 260Z tuned up to pass emissions, we decided to toy around with our non-running '73 240Z. Although we bought it non-running, we were able to drive it home from the PO's house after spending what seemed like hours coaxing it to start with carb cleaner shot into the carbs. That was about a year ago, and the last time it ran. Now, it just cranks & tries to turn over. Yesterday, we pulled the carbs off of our (now once) running '71 240Z and put them on the '73, as the carbs that were on have seized nozzles. Still nothing. Today, we swapped over the coil & ballast resistor & bought a new condenser for the distributor. Earlier, the diz…
