    S13 Throttle Body TPS issue

    If you are measuring the resistance of the middle pin and the resistance increases with an opening throttle, the open pin is positive, and the other meter probe is on ground.

    Wide body build thread! Fiberglass Mafia kit MOLDED

    Despite the reported trouble blending the front of the flare to the air dam, I think it looks amazing. Very nice work there.

    New widebody kit design

    WOW! Very nice.

    Bigger Air Filter = Better?

    I totally understand. I am merely suggesting that there may be a basis for the perceived difference.

    Bigger Air Filter = Better?

    Yes, more heat will be generated, but the intercooler will still take most of it out, and the boost pressure is regulated. Net result should be less effect on a turbocharged engine vs. N/A.

    Drivetrain swap talk

    I know everyone knows this already but 250hp/300ft-lbs is handled easily by the stock R200 long nose. Until the 8.8 became the hottest topic, the long nose R200 was considered just fine for all mild V8 swaps and some fairly upgraded ones too. Drag racers have run the R200 well into the 11s without issue (other than the lack of LSD options/ratios).
  7. LOL, if it performs as expected, I guarantee you someone (everyone) without one will.

    Rear disc brake help

    It looks like a Maxima caliper, 280ZX rotor setup. Similar to what I am installing this summer.

    I'll out on a limb and say that N/A engines seem more sensitive to pressure drops across the filter since the engine only has 1 atmosphere to operate on.

    V10 240Z build on YouTube

    Tell me about it. Last Binky episode was October, and all they did was plumb power steering and make a heater unit. So anxious for another installment, it's so interesting and amusing.

    V10 240Z build on YouTube

    I'm still following it, but in the sense that I cannot help but watch a train wreck in action. He's cut the body up into little pieces in spots that make zero sense. He cut right across the cowl, and cut all the structure out of the bottom. That chassis he fabricated to hold the M5 subframes is a guaranteed disaster, with no plan for how to mount the struts or body on it. I just can't stop watching now that the project is past the point of no return. He's in a deep hole and still digging, and I want to see how deep it gets before he throws in the towel.

    Hello from New Mexico

    Welcome from Colorado. Build threads are indeed a thing, I'd love to see what you are starting with.
  14. Nice work! I've been watching a lot of Youtube videos of rust restoration on Zs and other classic vehicles. I've nothing but respect for the patience and attention to detail this takes.

    Nothing will happen if it's too big. You will simply have less restriction.

    Failed Emissions

    My Federal 1978 280Z did not come with a catalytic converter. Judging by the limits you posted, it looks like your state uses the Federal emissions standard, and that should be able to pass without a converter. It looks like your test station has incorrect information - yes the California 280Zs came with converters, I think they were added along with fuel injection to meet higher CA standards.
  17. I agree, it doesn't look right. Either the bracket positions the caliper too far from the rotor, or the rotor is too small. In all the designs I've worked with, the entire pad contacts the rotor. It looks like this arrangement could overheat the pads.
  18. My attraction to the Z is more instinctual; I've loved the way it looks since I saw a brand-new one in 1973. I work as an engineer and I have that sort of mind where I appreciate how well the Z does was it was designed to do, and how everyone has a take on how to make it do better, while still keeping it's amazingly simple good looks.

    Wow, very impressive, and a beautiful build. I love that blue.

    Priming fuel pump

    Hmm, didn't know that. I thought my 1978 280Z did that, but it's been a long time since I ran the factory computer.

    Help NO START

    All you should need is a couple of gallons in the tank to ensure the fuel level is high enough to flow to the pump. Stock pump location is very close to tank bottom, but if it was totally dry you may have to siphon fuel to the pump inlet. A vacuum pump and a small T fitting at the pump inlet should be able to get that done.

    Priming fuel pump

    Purge the lines of what? The EFI is self priming, you just cycle the ignition a few times. The pump will run for a few seconds after turning the key on, turn it off and do it again until you can hear the lines pressure up and you are good to go.

    Home Built Z 'Full video build'

    Thanks for doing these videos, I really enjoy all of them, especially the Porsche 911. I have a little bit of regret with that marque, I had a friend give me an old 911 he ran on the track, it was in bad shape, but instead of repairing the engine and body, I parted it out and used the funds on my 280Z. I probably could not have afforded it, Zs are so much cheaper, but I feel like I missed a chance to drive one of those machines.

    Transmission options for 300hp

    My T5 is still good after many 13 and 12 second passes, and I know others with the same or faster result. That is 300+ hp and 400+ ft/lb of torque.
