it sounds like your ecu doesnt even know the car is running. do the relays click when you turn the key onto "on"?

Hi guys, does anyone know if this port takes a reference from before or after the throttle plate? r32vacport.bmp Need a boost reference for my wastegate, want to take one after any pressure drop through the i/c, and I've been told I can't take one from the manifold itself as the vacuum will damage the diaphragm. I was going to just tap into my piping before the throttle body, but then I saw this little port and got to thinking.... Cheers in advance

hi guys, my loom has had all its "unnecessary" plugs trimmed off of it... that includes the diagnostics pins that youre supposed to plug in order to get a code out of the check light. ive got the pinout so i know what pin is what, but i was hoping someone could help me through pulling some fault codes without the aid of the plug and check light. so question time, i know that theres a diagnosis transmit and recieve wire, and an engine check light wire. if i bridge the TX and RX wires, and run the check light wire through a bulb to ground, will i have recreated the check light system? thanks in advance

just digging this thread up. at a guess, they meant it outperformed it in terms of producing almost the same power at 66% the capacity. i saw this engine on trademe, i thought about buying it. then i thought about how i was crippingly poor, and wanting to eat more than noodles for the rest of the month, so decided not to

the sticky is for s30 model z's.. im not sure how different they are from s130s we didnt get turbo 280's down here, so the brakes would be pretty expensive :S

hi guys, i decided to post this here rather than the brake tech forum as theres a bit more traffic here. i'm looking for the easiest way to upgrade the rear brakes on a 280zx. not that keen on going to a 5 stud setup, or making up sets of adaptor plates. is there anything that bolts straight up? thanks in advance

hey guys, thanks for the replies.. i ended up sucking it up and paying $50 plus postage for the single hub. like i said, top dollar

just wondering if any other old nissans shared wheel hubs with the 280zx? need a new hub, dont want to pay top $$$ people seem to be asking for z bits now. cheers

ok thanks guys. i'm just waiting for my battery to charge then i'll try cranking her over. exciting times!

Hi everyone, i think ive buggered up my timing after changing my waterpump - everything was lined up, but after turning the engine over by hand a few times, my marks on the cambelt are no longer lining up with the marks on the cam gears. at first everything was lined up, then after one full rotation they were all out by about 3 teeth, then 6 teeth etc. The change is constant across both cam gears... Its the same belt that came off in the first place (not even 1000ks on it). So what I'm wondering is - should the alignment marks always line up after every rotation, or will it actually change over time (ie are the alignment marks only relevant for the time when you are actually replacing the belt) If its supposed to line up every time, what might I have done wrong? skipped a tooth somewhere perhaps? and more importantly, how do I reset the timing? Fortunatley it's not an interference motor as far as I can tell. I can set the crank pulley to TDC< but I'm unsure as to if there are any alignment marks on the cam pulleys, where tehy are, and where they shoul dbe when the engine is at #1 TDC in short, HELP!

did a search but didnt turn up much unfortunately. one person saying they hadnt heard of a 280zx tacho working with an rb20det, another person saying it should run as-is. the 10k resistor method i found on r31.com (australian skyline site) and that worked fine for the aftermarket tacho that i was previously using.

are you using the tinduck racing wiring diagram? (its a pretty common one on the net). there is an error in it with regards to the ignition and ecu relays, i had 4 volts mysteriously running to my black faced gauges until i worked around it. if you are running your fuel pump relay associated in any way with the ignition/ecu relays then you might be having the same problem

wow... so nobody here knows how to run the factory 280zx tacho off of the rb20 ecu?

Hi, 280zx factory tacho, rb20det engine/ecu i was running an afermarket tacho directly in front of the factory one, but it was pretty disorientating switching between it and the speedo, as they werent on the same plane. so i wanted to go back to a factory tacho. i've just plumbed the line into the factory tach feed wire, but no luck. what am i doing wrong? currently the line is pin 7 (tach feed) from the ecu, spliced with a 12v wire from some other place, and a 10k resistor, as this was the setup i needed for my aftermarket tach

might be able to help you out if you want, we have a tonne of 280zx's getting wrecked down in new zealand. hardly worth anything here is a pretty mint blue one http://www.trademe.co.nz/Trade-Me-Motors/Car-parts-accessories/Nissan/Interior/auction-250121347.htm 60$NZ but i wouldnt have a clue as to the shipping costs
