  1. I am in the process of developing a game right now, and i want to use the S-chassis as the main vehicle, the problem is i need either very precise and detailed measurements to make a 3d model, or i need a CAD model, would anyone know where i could get such things, for free that is, i would spend money on this, but as this is purely a passion project im not ready to spend 100 bucks on a model that is not accurate. If anyone is wondering i plan to fill the game with tons of different parts,(engine swaps and individual pieces, suspension parts, body parts, some interior bits.) When finished i will post the download link on this thread for anyone that wishes to try it out. Game is not currently licensed so things will be named differently to avoid any legal problems.
  2. Hello all, I'm struggling with a recently acquired, stock 78 280Z running very rich. As in 13-15 mpg combined, and all plugs are getting carbon fouled to the point one or more start misfiring completely. I changed the previous owners BPR6ES with fresh BPR5ES plugs, but after around 1000 miles I could again hear the 5 cylinder "brrt-brrt-brrt" and soon after the 4 cylinder "cho-cho-cho" ? I've been troubleshooting using my multimeter and the 1980 EFI bible, it's all well within specs except for the test 1- (3b) - Air flow meter resistance #2 (ECU pins #7 and #8). It gave a reading of 360 ohms, well above the 150 suggested by the bible. I pulled the AFM to test it more thoroughly according to the FSM, which gives the following instructions: 4.: 12v DC to terminal #6 and #9 5. Test voltage between terminals #7 and #8 6. Gradually open the flap and if there is a proportional decrease in voltage, the potentiometer checks out. And it did check out, the transition was really smooth. But I have no idea if the start and final voltages were within spec, as they arent mentioned in any of the manuals. With closed flap the differential was 8 volts. +8 at #7 and 0 at #8. At full open it was +8 and +8 for a 0 volt difference. Still not convinced everything was as it should I tested the resistance again. And this time it was 180 ohm, almost within spec. Weird. So I gradually opened the flap fully, and the resistance jumped erratically back and forth between 200-500 ohms. Then I closed the flap and made a new measurement: 260 ohm. Repeat: 230 ohm. Also confident the fault is not in my multimeter, it's brand new and doesn't hesitate measuring the correct resistance of anything else. So naturally I'm wondering - is my AFM actually working as intended? Or is it broken, but perhaps fixable? And if broken, is this the likely source of running rich? I haven't yet opened the AFM to fiddle about inside, but it certainly looks as if someone else has in the past.
  3. Tool for removing those stubborn rear suspension spindle pins! Remove the spindle in minutes with no cursing with this tool. The spindle must be removed to replace the lower control arm bushings on 1970-78 Z cars. We offer this tool to purchase or as a rental to U.S. addresses. https://zcardepot.com/driveline/rear-axle/axle-stub-companion-flange-chromoly-930-cv-racing.html?search=outer+axle
  4. So i just recently got my 280z to start and idle for about 5 seconds and then it dies while idling it runs rough any gas makes it die, fuel pressure tested at 38 psi and bleed down was slow and stayed at 20 psi. have good spark new plugs,wires, and distributor. Coil primary resistance is 1,6 ohms which is more than the recommended 0.6 ohms so i dont know if thats a issue. Cleaned all connections best i could and ran i new wire for the pin 1 on the ecu to the negative side of the coil along with swap ecus and drop resistor packs, i havent been able to verify timing yet waiting on a extra set of hands. just wanted to see if anyones had the problem before and knows some tricks. Also the car has sit for about a year prior to this first start ups, has fresh gas and new fuel pump and filter. I attached some videos of what it does Snapchat-1512447466.mp4 Snapchat-776157692.mp4
  5. Anyone have any idea what this body kit is? I've asked around some known suppliers, and none so far have any idea what this is? https://www.pinterest.com/pin/257971884883106901/ Got a 280z, and trying to find a body kit I like... ? Thanks in advance...

    A number of people refer to this document for repairing the 280Z clock. The thread where it was originally posted is no longer available so I'm posting it here in the tech articles. This is where is should be. No credit on my part. That goes to E. Bettio for writing the article and Monkey Man for posting it


  11. Alrighty, Ive got a stock 1978 280z and I'm currently installing an MSD 6A and Blaster 2 coil into the car. After reading any and all forum posts on the topic I came to the conclusion that I would need an MSD Tach Adapter 8920 in order for the MSD box to Communicate to the EFI by upping it to 12v. All my wires are in place and I'm getting a good strong spark. I put a voltmeter on the purple wire coming out of the MSD tach adapter and I'm getting 12v. Only problem is that I'm getting no fuel. It must not be communicating with the EFI somehow. Here's my Setup. MSD 6A: Heavy Red goes to battery + Heavy Black is going to battery - Red is going to Black wire with white strip (Ignition Key Wire) Orange is connected to blaster 2 coil + Black is connected to blaster 2 coil - White is not being used, I do not have a points system Violet and Green are connected to the Magnetic Pickups (I was told it didn't matter which way, I put green to green and violet to red) MSD Tach Adapter 8920: White goes to Tach Output on MSD 6a box Black is ground wire Red is connected to Black wire with white stripe (so two reds and black with white stripe all connected) Violet is connected to the blueish green wire that was connected to the coil negative terminal. Summary: I don't know what the **** I did wrong. Someone please tell me.

  14. Hey Team I have spent a lot of time on this forum and i want to say thank you all so much this is an incredible community. I have hit a brick wall and looking for a little help. Background story; I'm helping a friend of mine fix his 280z with 30,000 miles on it all original. Car has been garage kept all its life. Really really well taken care of. Apparently some one A-hole mechanic tried before me and failed miserably and i don't know what he/she messed up or touched. After them the car didn't even start. Fixed that issue. (FACE PALM) ?‍♂️ When you try to start the car it tries to start but never does on its own. If you give it gas than the car starts but it is runs rough(motor shaking). Have to keep the gas paddle pressed in just a little to keep it running. Car smokes white/bluish smoke from the tail pipes. (running rich) ( Gas smell). Changed the oil after the previous Mech worked on it smelled like gas was in it. Did a double flush much better now. Things i did and tested on the entire car: Spark Plugs - New Spark Plugs Wires - New Battery - New Battery Terminals - Cleaned Distributor cap - Cleaned and polished Dizzy - Cleaned and polished Pick Up - Adjusted to correct distance from roller according to 0.08in or 0.2mm Distributor Vacuum - Good Ignition Coil - NEW (built in resisters original ceremic resistor was missing) (https://www.holley.com/products/ignition/ignition_coils/street/super_stock/parts/8140C) Fuel Pressure - 22-25psi in when engine is off, while the car is running at low rpm 30psi+ ( 700 to 1k) Smoke test - No leaks AFM - Refurbished still sealed was installed last month AFT Idel screw - Did not mess with Throttle Body Screw - NO EFFECT when turning clock or counter clock Electrical - 12V all over from Body, Engine, - All good Ground Connectors - Clean Coolant Temp Sensor - Ordered Arriving tomorrow (CANT IMAGINE ITS THE REASON) Timing - Seems good 10 degrees of from original zero marking Cylinders Compression Test - 125 + on all Cylinders Injectors connections - look good Injectors - listen to them with stethoscope sound health strong tick HELP!!!? Thank you again for reading. I will be testing tomorrow.
  15. I just got a thottle cable to replace my throttle linkage. It's a 24 inch. Was wondering if yall could drop some pics of the throttle cable replacements yall have done. Need ideas of routing and connections. Please and thank you for the help.
  16. Hello all. I have been browsing Z site for the last 2 month and this sight has been the most hopeful. I figured it was time to become a member. My Z is at a stage between I love it and I want to set it on fire. Time and money but trying to have it back to road worthy again by spring 2020... fingers crossed. A giant thank you to all of yalls post that has help me in the last few months.
  17. I have finally narrowed down a shake in my steering wheel and bounce in my car to the 41 year old aluminum wheels. These issues, along with having to run a spacer for one of my Toyota 4x4 Calipers has led me to look for new wheels for the Z. I'm looking at the Konig Rewinds and Rota RB's but don't know what size and offset I should get to fit the car as best as possible. If anyone has upgraded to these wheels or has advise in general, I would love the feedback.

  19. Wondering if any of the historians out there can tell me when the 2-piece oil pan stiffeners started (and were discontinued?) being installed on S30 engine types (240/260/280). Thanks.
  20. Greetings, Ive been a Z owner in my own right since 2008 (1992 300ZX N/A) but inherited I inherited a 1971 240Z which needed a lot of work. In 2012 I unfortunately had to sell it to a good friend (ortegadrives on youtube). My father told me when I sold the 240Z that his 1977 280Z was as good as mine. My father has a friend interested in buying my 300ZX, which currently has electrical issues but overall solid car regardless. I purchased a Rebello 3.1 Stroker (actually from Dave Record in 2007 to install in the 240Z, still best purchase of my life). The stock 280Z engine was removed roughly 3 years ago by myself and OrtegaDrives and the engine bay is empty. We have a 5 speed transmission from an 82 280ZX, and a R200 LSD rear end. I have a list of to do items: Remove and clean fuel tank remove rear end/install R200 drop in Rebello w/5 speed transmission new fuel filter/fuel pump New fuel line (possibly) new tires/wheels brake job bushings Other than that, this car hasn't ran since July 1996. Is there anything I may be overlooking that must be checked out? Thanks for any helpful hints or advice! Mike
  21. Hello all, Before I go out and buy a timing gun, I was hoping to hear your thoughts on this short video clip. Finally got my 76 280z running and idling after finding a vacuum leak at the booster, but the idle is still really low, and I believe I hear it missing/bogging when accelerating ? idle adjustment screw seems to do nothing in either direction. New plugs, new plug wires, new water temp sensor, new battery, cleaned the injector plug connections, but that's about it. Thank you, Oscar VID_20190802_074213.mp4

    Quiet Muffler

    I am looking for small mufflers that I can possibly use. The new CA rules are no more than 95 decibels 3/4 of Power and read at 20 inches from the exaust. Contrary to what some people say about it not affecting classic/vintage or presmog cars <1975) this is not the case. The new law changes the penalty from a fix it ticket to a mandatory fine, and a mandatory visit to the state ref and a visit to the judge. The visit to the state ref puts your entire car under the microscope and even though it does not need to be smogged, it must have all factory polution equipment that came with the motor beign used. The visit to the judge will settle the case and the fine is 1000 dollars plus all repairs already expended. It also shifts the compliance issue from the state ref to the time you got the citation. You cant get the citation fix the problem, and go to the state and pass then go to court. You must prove that at the time you were stopped that you were compliant. The state inspection is just to prove you fixed the problem, all the required equipment is there and you are ready to go see the judge once they test your car and give you the compliance paperwork.. As stated above, some people think and wrote about it not pertaining to classic/vintage or pre-smog. Not true. The law reads as such (meaning of) : .....all vehicles subject to registration in CA are subject to.....no more than 95 decibels at 3/4 of power......when measure at 20 inches from the exaust...... etc.... no exemptions except for motorcycles, vehicles over 6000 lbs and off road vehicles not allowed to drive on the street. So, I dont want the hassle, dont care about losing a few hp if need be, howeve I do want a car that is compliant and will not give me legal headaches. So can anyone suggest a good SMALL quiet muffler that will keep the car under 95 db at 4500 rpm? My current set up is 6 into 2 into 1x2.5 inch, then splits into two 2 inch, each of which goes to a side slot underneath the side bumper behind the wheel wells. I am very limited in room since the gas tank is custom made and occupies the entire room underneath not leaving the original space on the left side open to accomodate a muffler. Any ideas????? Either 2 smaller mufflers for sides or one flat on the main, or perhaps some insert silencers??????
  23. So the electrical saga continues with my z... I have a 1978 280z and it recently developed a tendency to turn itself off when I'm driving. It started with it just turning off when shifting into reverse but has evolved into turning off with the right blinker once (I could hear the a relay in the passenger foot well clicking on and off with the blinker) and also just randomly while driving. Today it died in my neighborhood before i could leave and wouldn't turn back on until I jiggled the main wiring harness around. Because of all of this I suspect two wires shorted together since the turn signals and reverse are on the same circuit and removing the fuse for them fixes the problem but if someone could help me track down where in the harness i should be looking and what wire to the main ignition relay or other relay that would kill the car might cause this.
  24. Hey guys I’m new to this website but I have read a ton of stuff on here and it’s been a great help so that’s why I’ve joined. Anyways my 78 280z has been running fine for a while, I have all new fuel injectors, fuel pump, and afm. My fuel pump relay was bad so I wired up a switch to the wires where the fuel pump relay normally connects to and it’s worked fine. Recently however it has been idling horribly at around 500 rpm, but when I flip the fuel pump switch to off it jumps right back up to 1000rpm and idles fine until it dies from fuel starvation. It will also occasionally die out in addition to not accelerating sometimes. I’ll be driving and suddenly the power will not exactly cut out but not change if that makes sense. It’ll hold steady but stop reving and accelerating. It also blows darkish white smoke out of the exhaust when I rev it. I know it’s a lot of info but I can’t figure this out if anyone has had a similar problem or a solution please let me know!
