Hey guys, I have been contemplating the many things one can do to a 77280Z and I keep asking myself... what should I do after I have straightend out my body work and paint.. I am merely brainstorming, seeing as I will start moding most likely in march, give or take a month... I have considerd maybe replacing my EFI with carbs... but I have read on other forums that the EFI can be more finly tuned(however difficult). While carbs are easier to maintain and use but are not as accurate when tuning... I would like everyones opinions on this one... Thanks guys, Im still learning with my Z -ZZZap

I just completed an ebay purchase for a triple weber setup for my Z. I am so happy I should be dancing in the street. Not only was the price right (esp since everyone has them marked up over 200% since the factory went on strike) but they are Italian made not spanish. No idle air bypass to fool with, brass floats etc. Carbs on ebay some of my other recent purchases Timing set

Hey guys, i recently found a good deal on a fuel pump at part source, $75.00, because mine wasnt making alot of pressure. So i go in and ask the guy to double check on the computer that this will work on a FUEL INJECTED 2.8L from a 280z. he tells me again "yes yes yes" like i was an idiot, so i take it home and fire it on to the Datsun (took a while) and i start it up. Minus the start it up part, it clearly wasnt pumping out even half of the pressure it needed, when i took it off and tested it out with a 12v and a pressure gauge it got up to 3psi. So of course i swear alot and get pissed off, then i go the part maker's website, and under 240z,260z and 280z is the exact sa…

well, my rear SU died today on the way to work. i'm driving, then all of a sudden the car starts shuddering and dies. i think it's out of gas (since it's on E) and so i get a gas can and fill it. get the car running (rough) and pop the hood. tada! gas is pouring out of my rear air cleaner and the float bowl of the carb... great.... anyway, i'm planning on getting the ztherapy carbs, but do you think it would be worth it to check some other options (rebuild my own carbs, get rebuilt ones from a local source)? i'm kind of strapped for cash (very), that's the reason i ask. anyway, i'm leaning towards the ZT carbs since i'm going to end up getting them anyway, but it looks li…

Hey guys, for a while now i have been thinking about a l28et, can anyone tell me of mods people do on them and how the stock turbo performs, or if people replace them, and how to get more horse power out of one? Also, does anyone know of a 3000/3100 stroker turbo engine ever being done?

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.
