  1. My motor sits maybe 1/2 inch from the firewall.  I welded up the stock heater hose firewall holes and put in a bulkhead fitting right above the frame rail.  Was pretty easy to splice 2 sets of stock under dash heater hoses together to get to the bulkhead fitting.  The fitting has barbs inside the cabin and AN fittings on the outside.  Standard 5/8" heater hose pushed right into the AN fittings with no drama.

     

    Great minds think alike! this sounds exactly like my setup.... which i cant find a picture of right now

  2. I'm more curious how many times you've made a pass on it at your current WHP rating. Also Everyone is so wrapped up in spline count but I haven't heard much about diameter.. Wills kit uses F-150 CV/stub axles and not once does it mention the diameter of the shaft. I could care less if it had 100 splines. If the shaft was 1/4 thick it's useless.

     

    Also sunny do you know how large your Z31 outer stubs are? Do you know the diameter of your inner stubs? Thanks for chiming in.

     

    25 track passes at around 750 rwhp. Similar on the street.

     

    Ford 8.8 Axle diameters

    -28 Spline axle shafts with a 1.29" diameter

    -31 Spline axle shafts with a 1.32" diameter

     

    Not sure on the outers, cant find it right now. They're the 29 spline Z32 NA hubs, or the 240sx 4 lug. Same splines and size.

  3. From the video, it sounds like it (they?) were already broken. Possibly from the previous launch? Either way, they're toast.

     

    Somewhat surprised you got it to hook enough on those 18"? rims to do that.

     

    8.8 Here, with porsche 930 CV's, 31 spline inners, 29 spline outers (240sx) and Its holding up great.  Don't know the power the car is making, but it traps 150+, and cut a 1.400 60'.

  4. When I had a factory PCM, it was behind the glove box. 

     

    When I did my Holley system I modified the harness length to go under the passenger's seat.  

     

    If you're looking for a clean location, under the seat is pretty easy.  You will have to spend a couple hours soldering though. What's it worth to YOU?

  5. Finally got the car back up and running a couple weeks back. We have been oscillating between negative temps with feet of snow, to 50+ degrees, but I was able to drive it a while back.  Finished "breaking in" the new engine on 20#, and it is crazy on the cold roads.  It doesn't get traction, ever. I can roll into it at 70, and it will blow the tires off, lol.  Really looking forward to next season and getting some more reps in.

     

    Been MIA from the boards for a while, so I just thought I'd check in.

  6. What engine harness? Assuming its a 1 wire alternator, does it have the proper resistor in the exciter wire? Verified +12V to exciter wire?

     

    Have you had the alternator checked, or checked output voltage?

     

    1. Load test batter

    2. Check alternator output voltage (sounds like this is erratic)

    3. Verify exciter wire voltage and resistor.

    4. Detailed report back

     

    Electrical stuff can be a PITA to diagnose, but that should give you a good leg up.

  7. If you are pushing hard enough, even two catch cans (one in each line) is not enough to keep oil out of your intake. For 99% of the world probably would be great. Still not enough for me. Need to keep noodling on this some more as I would prefer not to open vent the crankcase.

     

    Why do you still have it circulating back into the intake? 

     

    I put a -10 on each valve cover and ran them to a single catch can. Plug/ cap all other spots on valve covers and throttle body / intake. Works like a charm, and doesn't even mist the engine bay.

     

    Why make it complicated?

  8. A lil tip for running an oil pressure sending unit up top in the stock location (drivers side, just behind the intake manifold). IF you have the stock electric sender, literally break or cut the plastic part off the sender and clean out the metal nut/thread part. Tap it with 1/8th inch NPT or whatever your sender is and bam. No need for adaptors. Plus its away from the headers. I personally dont like the JCI adaptor. Also you can use a stock datsun sending unit for your stock guage.

    Yep. I've done about a half dozen this way. Works well. Only thing that sucks is the autometer mechanical sender is huge, so you might have to run a 45* elbow on it.
