    In the same vein as aarang's comment, learn what you have. Could just be cam timing holding your RPM down. And beware discounted parts. There are some shiny cool-looking parts out there that don't actually fit and work. The stock injection parts aren't really very expensive. And the turbo variant requires more than the NA design. You should get specs on all of your parts and go through the engine to be sure that they're installed correctly. Cam timing, ignition timing, etc. Measure cylinder pressure, check valve lash, examine spark plugs... Find out the specs on the cam. Know what you have.

    There's a thread on another forum about aftermarket bars. Here's some links from it if you get desperate. http://www.nissanpartsdeal.com/parts/nissan-tube-oil-cam~13100-e3004.html http://www.yoesheadporting.com/product-page/687b6dfd-1bc5-8b50-6674-2e4f8b055f90 http://www.datsunstore.com/oiler-7077-used-p-1429.html http://www.datsunstore.com/oiler-7077-billet-aluminum-p-1428.html

    Wouldn't there be force on the tower forward under braking? Levering around the TC rod? Just trying to wrap my head around it. Straight line pushing the wheel backward, but rotational pushing the top forward. You could imagine if the top of the strut was disconnected and you hit the brakes it would rotate around as the bottom of the tire is pushed backward.

    Sounds like you got lucky. As I recall Casey took people's money and manifolds but did not deliver a product or return what he took. That's called stealing and people that do that are called thieves. http://forums.hybridz.org/topic/117103-senza-pari-manifold-group-buy-v-20/?do=findComment&comment=1097597 If the manifold does the same job the stock one did, with no change in power output, then it's is essentially an appearance piece, as was suggested early on.

    Your link doesn't work. And your comment is kind of meaningless since "works" doesn't tell anything. Beside that it's in the wrong sub-forum. Many would love to hear more details though if you want to do it right.

    Seems like this might be your problem. If you have a factory stock rubber mount try that before swapping bars. And take some decent pictures of the front mount with light. Your pictures are terrible.

    What happens if you use the stock mustache bar with the Sti diff? That will tell you if it's the diff or the bar.
  8. NewZed
    Search "GM HEI module 240Z" for one. Or swap to the 280ZX distributor ("matchbox" in CM's post above). This link covers much of your problem - http://www.fivestarmanufacturing.com/kat_s

    Is that an S30 or S130? Nothing wrong with exploring new possibilities. Here's a similar option using the Moog spring number for a Chevette. That option gets kicked around often for the S30's. http://forums.hybridz.org/topic/110278-need-stronger-front-coil-springs-for-240z/ Seems like people often leave spring preload out of their overall calculations. That determines the weight that the spring will hold up (depending on spring rate of course) before compressing. You can set ride height somewhat independently of rate using preload. Nissan uses a somewhat soft spring, but preloaded when installed. The tires are compressing along with the spring, when the suspension is in use. Lots to consider if you want to end up with a good ride after making your car look right.

    Testing - https://www.summitracing.com/ Let's see what happens... You're right. Image copied below. Trying Amazon now. https://www.amazon.com/ Amazon works fine. Summit must have a problem. How about a hybridz.org link to be sure. Do loop... http://forums.hybridz.org/topic/126603-site-redirecting-links-to-viglink/?do=findComment&comment=1183339

    You should have that head checked out, at least get the chamber volumes measured. It might have had port and/or combustion chamber work done, along with surface milling. It's probably not a stock head anymore so the CR calculators won't work. And choosing a proper cam will be worth much more than a bump in CR.

    That wasn't my point. I was just offering a clue. Nissan did make some one-off parts, apparently. The J30 short nose diff with the unique spline count for example. Wouldn't be a surprise if they had ABS as an option on a 300ZX. There are some things that didn't make it the the service manuals. But Infiniti M30 diff seems like a reasonable guess. Seems like kind of a distraction though. The real story is that your buddy didn't get what he thought he was getting. Hope he didn't pay too much.

    Maybe the early primitive anti-lock brake systems just controlled front versus back but most control wheels individually. You can't do that from the pinion shaft. And the pinion flange is at the same speed as the speedo drive, so no differentiation. And the ZX's went to electronic speed sensors pretty quickly so that signal could be used. The short nose diff ABS had toothed wheels inboard of the axle flange. Thar sensor is most likely a cruise control sensor, I'd think. Just puzzle-solving. Edit - wait. the !989 240SX appears to have a sensor like that, that measures pinion shaft speed. Guess they wanted to keep things separate from the speedo signal. But it's a short-nose. So close.

    You're right . Sorry Joe, I got my emphasis wrong.
  15. NewZed
    You're talking to Joe right? The topic was cruising until he came in with comments about short runs, and other people commented "stop thinking and just buy the parts from Joe". We're just trying to figure out how to get what we want without waiting for a group buy. These types of threads are where the ideas for the products Joe is now making came from. The free market is about competition. My comments should be helpful to Joe, and Whitehead, if they take the time to think about them. New ways to get there will be devised if the other paths are too time-consuming or expensive. Pretty simple concept.
  16. NewZed
    Starting fluid. Pop off a small vacuum line and squirt it directly in to the intake manifold. At least you'll know if it will run once started.
  17. NewZed
    Could the sensor be an aftermarket cruise control item? Red herringish. My "28" might be off. With 240Z, 280Z and 280ZX hub axles and flanges, and the two differential spline counts I get them mixed up. Ishould have left it at "my 280Z open diff axles fit the J30 VLSD diff". The 3.9 ratio and long nose implies early 300ZX doesn't it? That's why I was curious about if it's really a VLSD. You can tell by looking in the hole and seeing where the internal splines are. You can see where the two sides of the VLSD clutch split on the long shaft.

    There you go. Spending Porsche money on your Z.
  19. NewZed
    Nahh. Nothing wrong with saving some money. You're just used to living in Canada maybe. $165 is still a lot of money down here, Unless you're in the Porsche game.

    It's not the ordering, it's the waiting. There's a basic business problem here. If all of the parts come from the same supplier but people aren't ordering because there's essentially a group buy requirement, then keeping the customers separated kills the demand. Makes no sense. One guy orders from Joe and he says "you'll have to wait until someone else orders a pair", another guy orders from Whitehead and he says the same thing. Both guys cancel or don't order yet the numbers are there. How is that going to work? Especially today, when we're all trained to expect our stuff tomorrow, soon delivered by drone, to our doorstep.
  21. NewZed
    Just trying to keep my knowledge fresh, not arguing. But I have a J30 short nose VLSD with 28 splines. The older shafts slide in and fit but are a bit loose. And one is too short to engage the viscous "clutch" so it's essentially an open without the long axles, of course. What about the short nose/long nose question? Are there other long nose VLSD's besides the 1988 Shiro?
  22. NewZed
    What year car? Is it fuel-injected or carb'ed? Is it factory stock or modified? Will it start with starting fluid?
  23. NewZed
    By "don't fit" do you mean the spline count is different? Or the shafts are too short? Why do you think it's a VLSD? I'm not sure but I think that the Shiro was the only long-nose VLSD, unless Nissan used a long-nose VLSD with different axles on other models. They went to shortnose in 1990 and VLSD for the 300ZX's, from what I can figure. So long-nose would be 1989 or earlier. I think.

    Don't forget adhesion. The picture that the Energy Suspension link shows is just an old rubber mount filled with urethane to make it more solid. Getting good adhesion to the metal plates the factory mount uses will probably be difficult. Doesn't matter how strong or stiff it is if it peels off of the steel. Could be one reason that ES has that interlocking design. It puts a compressive load on the material and takes much of the tensile load off of the metal/PU interface. Just saying, it's not as simple as it seems and mistakes can cost.
  25. NewZed
    Can you make a video? I'd like to see it, I'd laugh I'm sure. The gaskets are just compressed rubber that eventually hardens up and shrinks, or the previous guy tried to reuse old shrunken gaskets. Pretty simple repair. http://www.thezstore.com/page/TZS/PROD/11-3402 The 3-4 second running then dying is still probably your AFM switch.
