  1. if someone else measured a manual trans turb pump and it was also 40mm, then it seems that all turbo pumps are the "high flow" type.

     

    You should not assume this just because "someone else" checked one pump from one car.

     

    Your best bet is to check with Nissan and you'll see that the part number for the high volume pump was specific to the turbo automatics.

  2. (new problem btw - i sacked all these things in ziplock bags for shipping, then sharpied the bag with piston number... engine oil ate my sharpie, and now i'm not sure which is which... wtf do i do about that?:ugg:)

     

    check the sides of the con rod and con rod cap: they should have the cylinder number stamped on them.

  3. Also if I do decide to buy from the oring nazis which do I get, small or large? To be more specific these are the orings that push into the intake manifold and seal the tip of the injectors to the manifold.

     

    To seal the tip of the stock injectors, you need the small o-rings. The large o-rings install around the body of the injectors so that they fit snug in the plastic injector holder.

  4. I'm having a difficult time finding these caps. They install on the outer joint of the Z31 CV axle ("Double Offset-Birfield" type). They are NLA from Nissan and I have been unlucky at the junk yard.

     

    Short of having a set faricated, I thought I'd check with you guys to see if anyone has an idea and can help. Nissan calls them "slide joint plugs". I have attached an image for reference.

     

    Thanks.

  5. There really isn't any adjusting you can do other than to bend the arms inside to make sure they are making contact.

     

    I don't agree with that statement. There are 2 fasteners that attach the TPS to the throttle body and the TPS can be rotated for adjustment.

  6. Check to make sure your valve cover has the baffle in it that creates a chamber within the valve cover. If you take off the valve cover, you should not be able to see the opening where you have the breather filter installed.

  7. I bought my 81 280ZXT at the beginning of last summer. Flew to New Jersey and drove it back to the midwest. One owner, turned 70K miles on the way home and still has the original floor mats. Now its a sunny summertime driver only.

    ...Beautiful car! It looks like it is in such great shape that I wouldn't do anything to it other than maintain it. It still amazes me that this car sold for over $17,000 when new. Good luck with it.

  8. I let the car sit overnight and change the oil cold the next day. When you shut down the engine the oil is hot and drains into the pan: all the oil that will make its way to the pan, does so.

     

    Why would you start-up the engine to heat-up the oil just to drain it? Not all of the oil will have made its way into the pan.

    This makes no sense to me.

     

    Besides, who enjoys doing a hot oil change!?

    The first two pictures show the inlet points in the gasket surface. You will notice that there are holes in the head that are blocked off by the HKS steel gasket. These could flow water if the gasket was opened up. In the second picture you will see holes in the head gasket that do not have holes going into the head. This makes me wonder if this was for a reason, or just a manufacturing convenience, so that 1 head gasket design would fit many application of the different years. I wonder if an improvement could be had by opening the gasket up to the holes in the head, and the head up to the gasket. Hmmm.

    Now here is my question:

     

    I am about to install a new steel head gasket (replacing an old steel head gasket) and I realized, as shown in the first picture above, that (2) coolant passages are blocked by the gasket.

    Did you found out what the reason is, if any?

    Does the stock Nissan gasket block the same passages?

     

    Anyone?

     

    Thanks,
