    240zxt mpg?

    in Turbo / Supercharger

    Posted

    Yesterday I fill up my tank and went on a 210 mile trip at 105 miles my gas gauge was reading a little less than 1/2 full so I fill up and check my miles it took 6.8 gallons to fill the tank( 76Z). Which amount to 15.4 mpg? I was hoping to do better than that or am I wrong. I was thinking around 25mpg. This is the set up I have 83zxt, 1980 sp. and the stock 240z rear end I'm running about 8-9psi boost.

    I did notice at 70mph the rpm was around 3500, that seam a bit high. Is three a better tranny, rear end combo that would give me better mpg with good performance?

    TDC?

    When I set my car (83ZXT) to TDC (timing mark on the sprocket and the line on the cam plate are lined up, the mark on the crank pulley is lined up at the 0 degree mark, the cam lobes are up and the valves are closed). I pull the distributor cap and the rotor is between the #5 and # 1 plugs. Shouldn't the rotor face the # 1 plug at TDC? Also when I put a timing light on the car it was at 32 degrees advanced, I moved the distributor the other way to lower the advanced and the car ran worse that's when I though to check the timing marks. I set the car to TDC, 4 times and every time the rotor was facing between the two plugs 5 and 1. What could cause this would the distributor shaft happened to be off a bit? Is it possible to pull the oil pump and turn the shaft a tooth or two to get the rotor to line up with the # 1 plug?

    I have a 280zxt in my 240z i was looking at the wiring list posted, and have a? i hope you guys can help me with. on the plug #2 there are two yellow wires, one for the A/C and other for the start signal this is the one i having problems with see how do i tell which one is the start signal as the are both on the same plug. i have not hook that wire up yet, the car does run and drives What does that wire do, and when i figure out which one it is does it go to a hot + source all the time when the car is running or should it only go hot when I'm cranking the car over and when the car stars it should go dead?

    thanks

    turbo vaccum lines

    I finally got the 83 turbo motor in the 240z and running althought not quit well yet, thanks to all that have responded to my posts.

    My next question is the vacuum solenoid that mounts under the AFM., where does the lines connect to? I know the big one in the middle goes to the AFM boot, also know that one of the small lines goes to the EGR but i'm not sure which one, can some one take a look at their car and the me where the lines connect to. A lso there's a small vacuum line that is connected to the vacuum canister where does this one connect to as well.

    I got scotties downpipe and there is not a opening for the piping that runs down from the EGR to DP. like the stock one has, Can i plug the EGR, will i have any problems if i do?
