After installling the new plugs and plug wires today and finally getting my 77 280Z running (running excellent I might add) My father and I noticed a hesitation(cut-out) just after the tach hits 3000 RPMs, does anyone know what might be causing this?? I though that maybe it is something within the distributor (I.E. the cap and rotor) or perhaps in the coil. Any opinions? *Note* this did not happen before today...

my mechanical fuel pump on my 73 quit working and because of diffulty removing with the ac bracket and could not find a pump in stock of good quality, I put on an electric fuel pump. Ilooked all over town for a low psi (4.5lbs) type. purched a Facet box style pump. Installed it back at the tank where the original assist electric pump went (long dead) used the same mounting plate and was able to trace the electical wires to the relays and jumper them. My question is ,this type of pump clicks all the time and is kind of annoying. On the newer cars with pump in tank you only hear it pressureing up and never hear it again. During my search I ran across a Holley hi psi pump…

Hi everybody. I'm a newbie and not very handy with mechanical issues. I have an 83 280zx (non-turbo). I ordered a new idler pulley from Advance Auto; it was around $16. Is this right, or did I just order the bearing only? When you go to their Parts America site and put in "idler pulley", you get a bearing. Is that what I need? Sorry for the possibly dumb questions. Thanks.

Hey Z people, Has anyone or does anyone know weather or not I can turbo an F-54 block with flat head pistons. I figured out the compression ration would be 8.07:1 the stock turbo L28 was 7.45:1 (I think) Is the extra compression gonna be a problem? Rock on Z people

I have been looking in the new MSA Holiday catalog and came across the Crossflow Radiator. Does it cool better than a top down stock one? I would guess the fluid stays in the cool lines longer then just flowing down with gravity? I would also like to know what some of you opinions are on the electric water pump. Thanks

Have found an engine from an '82 280zx. Have only discussed this over the phone with the yard owner and was told that it has a P79 head on a F54. First is this the correct head for the '82? Or has the previous owner switched the head from a P90? The car has about 120,000 miles and is a 5-speed. Looking for a winter project and trying my hand at a rebuild. Any thing I should look for before buying this? The car has the gas tank and radiator gone so I can't start it. Thanks for the help.

Ok guys, picked up my 72 240 today and already started working on it. The Good; has the round top SU's on it (built before 9/72 i guess), and the Single point distributor (prime pertronix conversion). The bad; Won't start. Checked ignition that's good. Fuel looks real filthy in the fuel filter, but no gum/gunk in the lines. Sprayed starter fluid in the intakes and she fired up one crank! But then she dies. It's running on the starter fluid only. Here's my question: I stuck the feed hose in a tank of clean gas with a new filter. If you look at the clear filter it looks like the gas is barely being sucked in by the Fuel pump. You literally see it trickling into the filter. …

First off, a disclaimer: I am an EFI guy, so these carbs blow my mind. I've got a 240z with an L28 and the SU carbs. This motor is on its last legs... but still runs pretty strong. It burns a lot of oil, however. I am going hybrid with this car eventually, but I need it to get around until that time. It seriously runs nice and strong everyday, but I've noticed a problem late at night when its really cold out (southern california, not snow mind you) I'll be cruising in high gear on the freeway and it just cuts out. It does it mostly when I apply the throttle under heavy load, like high gear uphill, or when passing cars. If I try to throw a lot of throttle at it quickly, it…
