Having done what I hope is enough research, I have started down the road on my next off-beat modification. I decided to pull the trigger to go with the Patton Machine fuel injection kit on my 260Z. I still think I'm going a little lean at times at the top end with my current SU setup, and I hope this will remedy that situation. The cost appears to be less than sourcing a non-egr FI intake, AFM, MS setup, etc., and it seems to be nicely sorted out. I'll try to remember to take a lot of photos for posting. I hope to get the setup in March.

Hello all. I'm a newbie to the Z world-- just bought a very nice 76 280Z: http://devnulled.com/gallery/280Z-calitocolorado I've worked on / modified DSM's for around 5 years, and can do about anything on them without a problem except rebuild engines, trannies, etc by hand, but decided it was time for something new. Anyhow, on the drive home, I noticed it was running very rich. I had an emissions test done today, and they also confirmed that it was rich. Being that it's fuel injection, I'm not quite sure where to start. I would assume that perhaps the spark is not strong enough? I have some new Taylor wires and NGK plugs to throw on this weekend, so that's a star…

Hi Engine cranks but not start. This 3 days after collecting the car at the garage for wheel/tire change. Guy told me "engine is running on 5 cylinders". Did not notice, but remember now 8 monthes ago that another garage owner change the sparkplugs...may be one was brand new but dead. Car went fine even if driven less than 200 miles or so. Could a dead sparkplug flood the engine with fuel with time? A possibility to explain why not starting anymore??? Anyway, did the continuity test and here are the results: Except for the water temperature sensor, everything's seems OK. Anyone has a concern regarding these results? …

As stated before this car has not been on the road since 1996 and the throttle body is quite dirty and needs a soaking. Throttle shaft feels good and tight, operates smoothly. Throttle position sensor was immaculate. The plastic cover did it's sealing job perfectly on that part. The BCCD is another story along with the dashpot. Not in reuseable condition. Any suggestions? The BCCD seems to be a bit of controversy on the Forums. Can it be eliminated without major driveability issues? I have not found any replacement parts for either the dashpot or BCCD. The rest of the throttle body will be soaking for a few days. Will have to wait and see how it turns out. Than…

Well I decided to jump into the EFI game with both feet. Here is what changed this "old school" boy's mind. Weber look-a-like throttle bodies with built in injectors and TPS. Jenvey Heritage Throttle bodies is what they go by. I get the old look I can't seem to do without, with all the modern advantages of EFI. You may notice that there are only two, and this is a Z forum, but as most of you know there is 510 lady in my life that I'm currently enfatuated with. I can always buy another one if I ever come to my senses. These are 45mm with 350cc/hr injectors. Should do. https://www.onesixindustries.com/products

After I bought my 71 240z, had fuel overflow problems. Discovered there's no expansion tank and the fuel tank itself is from a 75-76 280z. Sourced a good 240z fuel tank and the correct plastic expansion tank. Fabricated the hoses, now trying to install the tank. Seems like the plastic filler neck is not quite lining up correctly with the fuel tank. Or maybe I'm doing it wrong. Can't locate the owner who did the swap. Wondering if fitting the 280z tank required a 280z filler neck. I see there are unique filler necks for 240/260 and 280. Is there a way to tell the difference, so I'll know if the filler neck is why the tank doesn't quite line up? Thanks for…

I'm on page 33 of the fuel injection bible, http://www.atlanticz.ca/zclub/techtips/efisystem/280zfuelinjectionbook.pdf No. 5 Power relay control unit injector test, it says to disconnect and reconnect the ignition lead wire several times while listening to each injector, so what do they consider the ignition lead wire? The pos side of the coil, center lead of the coil? I have a no start situation so working my way through the steps. Thanks

I just got my car checked for emissions again so that I can renew my tags. We're on a two year cycle here so that gives plenty of time to mess around and get it screwed up . I had my car running greatly and went straight to the emissions check station without doing anything to help it pass. It failed, of course, so I spent the next few hours dinking around with the idle air bypass and my fuel pressure and failed three more times. So I went home and realized that I was using my MSA AFM that I had bought new nine+ years ago and that it had always run rich. I don't know why, it just does. No matter how far I back out the idle air bypass I couldn't get it to lean out. …
