  1. I spray the bores and the pistons with WD40 then drive 'em home.

    I'd like to be in the middle of that pajama party!
  3. Nissan used high quality materials in their engine blocks, so cylinder wear is not always an issue. Only a couple times in my life have I ever seen an L block with the (common to Chevy and Ford) ridge at the top of the bore. Out of round cylinders are more common, but again, not always an issue. The Hastings rings are quick to break in and last a good amount of time and are perfect for someone on a budget. Not because they are cheap, but because they allow you to ignore the cylinder wear. Ultimately, I would have the machine shop help in the decision making process. Have them measure and give their $.02 on the rings.
  4. For low budget rebuilds, I like Hastings sprayed chrome rings. Because of their construction, they break in quick. The Sealed Power rings you showed appear to also have a sprayed chrome top ring. Technology has changed over just the past couple years and it may be worth reading up on. Here are two good articles - https://www.hastingspistonrings.com/tech-tips-faqs/hastings-piston-ring-set-composition-recommendations http://blog.jepistons.com/piston-ring-materials-explained
  5. I predict Holley telling you that the location in the t-stat housing is ideal.

    Dudes in a pillow fight. That's weird.
  8. Yeah, I never saw this as a valuable option for Datsun owners. I would be surprised to ever hear from the OP again.
  9. Mike, it seems your intentions are good, but i do really think you are detracting from the discussion here. You've made your points. They've been addressed as well as they possibly can. The cash outlay is not much. I don't care who owns the molds. I don't care if they start selling them out the back door. I don't even care if they are not 100% OEM quality. Something is better than nothing. As I said earlier, I will buy two sets, but not right now. Cash is not on my side at the moment. People, please, if you want these parts, don't miss out on this. Everything seems legit and the terms are fair.
  10. One thing you could do to sooth the nerves here is to give some references. Would you be willing to share some of the shop names you currently sell to here in the USA?
  11. I am absolutely strapped for cash at the moment, due to a construction project expanding my shop. I have always said that I would buy two sets, even though I don't own a 320 (actually looking at one locally soon). I don't want to hold up the process either, but I can pre-order two sets in a month or two, but no sooner. Sorry, broke as a joke!
  12. Loose pinion flange? Bad pinion bearings? Does it leak any oil? This would be a sign of something wrong with the pinion flange or bearings.
  13. Wayno - that's the best way. Weld in the new piece before cutting out the old. Mathius - the parts you pictured are probably adequate, but I would add more reinforcement to make it better than adequate.

    I am speaking for myself here, and kind of thinking out loud. Taking my thought process to a conclusion. I say no harm, no foul. If someone enjoys buying and resurrecting something, and is able to get a good price for it upon sale, and the buyer is willing to pay the price, who gets harmed? The people who have owned and enjoyed these before are the only ones who could possibly get harmed, and even then, only if they want to buy more of them. Where it becomes tricky is if you own something that's increasing in value, and you have a hard time resisting the new prices. Parts prices is possibly the only place where an enthusiast may see price increases that actually affect them. Case in point - my father-in-law's 240Z. He bought the car used in 1972. He's covered it under two soft covers inside a clean garage its whole life. The car has just over 60K miles on it and is perfect in every way, except for one minor ding and some repainted original hubcaps. Well, he's aging, now 87 years old, and I feel that my wife and I are the inevitable future owners (not pining, just speculating). Like the old woman with a Virginia ham under her arm and crying because she has no bread, I almost feel like we will need to sell it. Blasphemy, right? My shop is not a good place to store cars. It's a working shop. I don't have any other place to store it. Combine that with the fact that I probably won't be able to resist the urge to modify it, because who wants to drive a stock 240Z? Ownership of something so nice is a huge responsibility and I'd hate to have something happen to it on my watch. So my thought of long term ownership, keeping it in the family, has me thinking of losing a valuable parking space in the shop. Is it wrong for me to want to sell it? And if I do, is it wrong for me to want to break sales records? I actually don't know the answer to the first question, but I do know that fetching the highest price possible is no crime. There it is. My verbal diarrhea on the matter of value and all it entails, for me at least.
