    So after it seems years without a tach working, I finally got it going. Long story short, I pulled the tach and wired in the MSD 8920 right at the back of the tach at the harness. I cut the black/white and green/white at the plug, which connect the current loop of white wires, and wired one to 12v, and other to the red on the adapter and it worked. So happy to keep my original clean tach.

    Got the 8920 tach adapter to work with my MS3. The key for me was to wire DIRECTLY off the tach plug in the back. I cut the green/white and black/white wires at the connector and ran wires from there to make the tach loop. I then wired exactly per instructions. I think the path of current takes to many detours in the harness to try and pick up the tach from under the passenger side wiring.

    The attachment that the OP put on there shows CB for the current type tach. I think it would be easier to try and get a 73 or later to work. I didn't think the later tachs like the 280s mount in to the dash right. So maybe the 73 is your best option?

    I was trying to talk my buddy into making that so I could try it, let me know how it goes. I've been trying to get a 8920 converter to work, but no luck.

    I bought the cheapest dell they sold that was touch screen, I think it was 300$. The computer is not the best, but great for the MS. It's the smallest screen they sell anymore, 10" I think

    I bet it would be very similiar. I would think that combo would work well. The small chambers on the Mn47 would bump compression slightly, but maybe not much at all. I don't know anything about the W24 block, but as long as it's Nissan, it should work:)

    Noticed that on my 40's also. No way that I saw to change this. I guess you have to remember that the airflow would help pull it into the cylinder.

    Well your budget is tight, so I would just shoot for a freshen up of the n42 stuff and throw in a cam. Flat tops would be better for a hot cam, but I think you will blow thru 1000$ pretty fast. Get some electronic ignition and concentrate on a good tune. And search until your eyes bleed.

    Derek, this would be easier for you to finish than me. The only part that was giving me a hard time is coupling the oil drive shaft to the Jeep sensor shaft. I know you could come up with a way to machine the jeep shaft groove to fit the oil shaft tang. I also was going to come up with a bushing to keep shaft side play to a minimum.You can buy these new all day long for 20$.

    Cheap, hidden , accurate, stable.

    Why not use the 240sx TPS?

    It's a 4% increase in size, but not sure how that calculates to flow
  14. madkaw
    All the searching I've done on these cylinder heads and I've never read a direct comparison between the 2. How much flow are you leaving on the table by not going to the larger valve? Would building a stock bore L28 with a larger cam, headers, etc.. be undermined by the smaller valve? I should add that I am staring at an MN47 head as I ask these questions. With the D shaped ports that narrow down to 31mm it makes me wonder if the larger valve is still beneficial.

    That's cool

    Forget all that optical crap, use a cherry hall sensor to read off the flywheel for 30$ and you don't even see it.

    What about an e88?

    This pan is on my 82 810 wagon diesel. I noticed it when changing the oil for the first time after I got the car. Another good part from the diesel Maxima

    Love to hear more about this. What application was the motor for originally and what does a motor like that cost?

    I never did finish the cam sensor, so nothing definitive for you there. As far as the detonation, I has 2 spark tables going at once and the timing was way advanced.

    Distributors? How primitive!

    I found that using my vacuum log to hook up my pcv was great until my MAP sensor at the bottom of my log collected all my blow by. I was not running a catch can, but I will now. I do run my motor hard , so some blow by is to be expected. I have to make a significant mixture change on the triples when using a pcv vs. not using one.

    You need to fill out your signature or be specific with which block, head, etc. I used the head dowels to line things up. Gaskets come in various hole sizes, so I doubt you've ruined anything.
