  1. Im finally getting around to building my 240z's gas tank. I will be installing the hyper fuel tight fit in tank retrofit kit with 525 lph pump to eventually power e85 on for my rb26 as well as a speed hut fuel float sender. Now that I have the tank cut open I'd like to weld in some baffles. After searching around online there are a lot of different methods being used, Iv came up with a few of my own and would like to get some feedback on them before going ahead if possible. Right around the pickup Im thinking about a maze like this and surrounding the maze im thi
  2. Just bought the FAST EZ-EFI kit from Z Car Depot for my 1983 280zx. Put it on my car the other day and it runs worse than it ever has. Car will idle but is very hard to start and really rough when it's running. Using any more than 1/4 throttle will stall the engine. When I am able to rev the engine it's terribly rough. Feels like or an ignition timing issue. I know that when I removed the old EFI harness I disconnected a connector going into the distributor and the new harness did not have a connection to plug back in to the dizzy. Since adding the EZ EFI, ignition timing has retarded itself a

  4. Are you a car enthusiast looking to get your foot in the door of the aftermarket racing parts industry? We build and sell racing fuel injection systems, and we're looking for a technical sales and service position. We are looking for someone with experience with installing and tuning tunable aftermarket fuel injection, even if the experience so far has just been on your own personal project or friends' cars rather than paid work. MegaSquirt or AMP EFI experience preferred. Here's what you will be doing. Entering phone orders and creating customer accounts. Helping customers de
  5. Hello everyone! Im new to the Hybrid Z forums so I thought I would start a build thread for my build on my 1975 280z. Current car: 1975 Datsun 280z Mods: Subaru Power Steering conversion, Full Eibach suspension, aftermarket swaybar + full polyurethane bushing conversion, Toyota front disc conversion, aftermarket A/C installed, 240z driveline, (im probably missing some things so I'll update it as I go.) I have roughly 20 years of receipts of all the work done to the car. I just recently acquired the car so everything listed above was done by the previous owner. Now here is my p
  6. When you guys have done a 240z to EFI conversion whether it's MS or stock ECUs where do you route the EFI harness through the firewall? Do you cut a new hole near the brake booster or repurpose another hole? Looking for ideas. Thanks
  7. After kicking around many ideas I decided to go with an external surge tank and external pumps to feed the fuel rail of my rb25det in my 240z. I tried an intank fuel pump previously. The intank pump is the way to go for sure as long as you have adequate baffling and good general design. My problem stemmed from a poor design and using a rusty tank a buddy gave me. I started a thread on that. http://forums.hybridz.org/topic/94261-bonks-efi-fuel-tank/ I will update that thread with some lessons learned soon. Luckily I still had the original tank I pulled out of the car
  8. This is really cool, and way overdue for the marketplace. Most racers already ran -6 A/N individuals to Weber DCOE's from a fuel distribution log... Cost is comparable to new Webers, and the hidden TPS Option keeps everything away from prying eyes! http://www.jenvey.co.uk/products2/twin-throttle-bodies/dcoe-heritage-bodies/heritage-dcoe-twin-body-40-48mm-tdsxx Crap, thinking about this, I should likely have put this in Fuel Systems Sub Forum. Mods move if you like.
  9. Guys, I'm still trying to get to my first drive after a long build. Last week I had an electrical issue that a few of you posted replies, and "rsicard" identified the issue. Thanks to everyone. So now electrical issues are behind me, I think. And I'm having a fuel delivery issue. The stock '77 280Z fuel pump is supposed to be good enough for TPI according to the JTR EFI book, but if I read between the lines I think it is marginal. No matter, my stock pump developed a slight leak between the halves of the fuel pump body, so a few weeks ago, I replaced it with a new 280Z pump "
  10. Hello All, I had a frightening moment with my '77 280Z after replacing old fuel hoses. I started it up and one of the injectors with the factory crimped hoses tore and started spraying fuel down on my headers. Luckily there was no fire and I had an extinguisher in hand. What has me really disturbed about this is that I purchased these injectors last year and they've only been running on the car for a total of maybe 2 hours at most. My fuel pressure doesn't exceed 40psi (have a mounted gauge). I replaced the hose on this injector, which is described in other threads on this topic. I

  12. Stock EFI system on an L28. I have swapped to a gm style HEI module. New Harness. The injectors will not fire, pin 10 on ecu is seeing 12v, all injectors have 12v on both pins reference to ground, and the car runs fine with starter fluid. I know i have spark, the tach wire is wired from ECU pin 1 to the negative terminal on the coil. Do i need to wire in a dropping resistor for the ecu to see the pulse? Does the car need to see a start signal to begin firing the injectors? Does the ecu need to see 12v through the air valve from the fuel pump? any help would be greatly appreciated.
  13. I have an L24 with SU carbs. I've had this idea of the ability to go from carbs to EFI and back relatively easily.This would require a bolt on replacement for the carbs. I'd still be using the stock intake runners and air cleaner. I'd also try to keep the TBs the same length as the carbs. This is what I've doodled so far. This uses a compact EV14 injector: http://www.bosch-motorsport.de/media/catalog_resources/Injection_Valve_EV_14_Datasheet_51_en_2775993867pdf.pdf Some fuel rail I found the dimensions of: http://www.rossmachineracing.com/images/large/dash8wire.jpg And
  14. hey guys! I was just wondering, is it possible to use a non-EGR intake manifold with the stock 280zx turbo ECU? also,if i upgrade the injectors to 320cc,can the stock computer run with this? im turning my n/a into a turbo and dont have the cash to go aftermarket engine managment yet,so i would like to use the following..

  15. Hi Guys, I'm still pretty new to the forum but I wanted to start contributing right away! I just bought a 1975 280z that had been sitting for over 10 years and was the victim of seized fuel injectors. There are a couple of options on how to handle the situation, one would be to replace the old injectors with new ones. Thats a solid choice but oem injectors will set you back $350+. Another option would be to buy refurbished injectors. Again, that's a fine option, but since fuel injectors are sealed units that cannot be opened, all you are really buying are old injectors that have been cleaned.
  16. I was almost ready to deliver a 1976 280Z Restomod to my daughter 6 months late after her 16th Birthday! We started the car up and went to pull it into the shop for final buffing/touchups and low behold the engine died and would not restart. Needless to say my daughter was heartbroken. The car would crank but not start. If the engine was cold, it would start, run one minute or less and then die and not restart for hours. At first check my plugs were all soaked with fuel so we thought "flooded" clean the plugs, suck out the cylinders dry and and try again. No luck, no start. Pulled the pl

    I am currently in the market to start sourcing parts for a turbo swap into my S30. I am interested in anything you may have to get me to my goal, which is as of right now, to run a stock l28et in my 240z. The more complete of a swap the better for me. Let me know what you've got
