  1. One essential part which does not seem to be discussed at all is the chassis/suspension, something which is crucial to real performance on a circuit. Just look at the 370Z, it had adequate power but never made it on the race track because others handled better. Unfortunately the 400 looks like it uses a parts bin chassis and suspension unlike the S30 which resulted in a car that still gets raced successfully today. Without a potential racing history the 400 will just be another sports car which has to compete on price, power and appearance, all of which are market variables that change regularly and lead quickly to a market failure of one car or another.
  2. The 280ZX was introduced as a DATSUN 280ZX, by 1980 the badging was still DATSUN 280ZX, but with an added note "By Nissan"

    That tool is for knurling the sides of bearing caps, and raises the metal up to 0.01" (.25mm). It is for fixing caps that have become loose (common in race engines that see frequent assembly/disassembly cycles). The outsides of the caps where they slip into the machined recess in the engine block are worked over to raise the surface (remember, the knurling process displaces metal, the resulting surface having much less surface area than previously as it is now peaks and valleys), then sized to fit. Shims are used after worn caps are resurfaced where they mate with the cylinder block, to help maintain the crankshaft centerline position in the block. Replacing the missing cap will require a line bore because the cap isn't matched to the block, and wasn't machined the same time as the block and all the original bearing caps. Since it is impossible to machine just the one bore, and have it be aligned with the other six journals, they must all be machined together. It is a routine process in a machine shop that does engine machine work. The OP would be well served to find a cap that was from the same journal on the donor engine as the one that is missing on his, as they are all marked for location and direction, to avoid confusion during subsequent engine teardowns.

    I'll stop after this. Here's a cap surface that looks kind of knurled. But it's just a factory machining flaw. The engine ran. Good info in the article though. https://www.enginelabs.com/engine-tech/enginelabs-blueprint-series-the-keys-to-proper-block-align-honing/ (Right) JGM’s owner, Ryan Peart, showed us this big-block Chevy main cap out of a running truck engine...

  6. Winki says "By 1986, Nissan had phased out the Datsun name" - from memory, I think that is about correct.. it took several years to update all the Dealer Signs, brochures, letter heads etc. - which added to the "Brand" confusion.
  7. The seller left too many things undone and set his reserve too high. No sale.
  8. Test fit of rear rotors. More pics to come. Will be looking in to proportioning valve. Hoping it all works!
  9. There is a chrome shop about 6 miles from me, Whitworx Chrome & Metal Polishing, in Lincoln that does excellent work. Zup had his bumpers done by them about 6 years ago and the finish looked great then and still looks great today. I will have my 240 bumpers done by them sometime in the future. They do a lot of "show car" work. http://www.whitworx.com/
  10. I finally pulled these out and cleaned them up a bit. Looks like I have all four with TOB's on them. The shortest ones bearing is a little different that the other three. I took measurements overall and to the ear. If anyone can suggest other measurements let me know ant I will update.

    Ok, I'll be third in line as a source for caps, behind I think CaptO and Terrapin Z if you decide to replace the one cap and go the line bore route. I have 2 blocks which are not likely to see a engine bay, one is missing one cap. Genuine Nissan bolts included.... The caps are numbered from front to back with a directional arrow, which number is missing. Might as well go for numbers matching. lol

    The thread you linked to discusses a bearing in a bored hole, but doesn’t say it is a crankshaft journal. Reading further in the discussion, knurling valve guides to avoid replacement is commented on. There is also discussion about the lack of suitability of knurling a bore to correct for bearing retention. Indeed, knurling would only be able to “correct” for a couple of thousandths of an hour inch, and even then there wouldn’t be enough contact to keep the bearing from spinning inside the bore. So knurling might be adequate for tightening up worn valve guides, but it would be a fool’s errand to expect it to correct for an incorrectly machined crankshaft journal.
  13. Another good thing about going to the site on your phones web browser. I "HIDE" stuff all the time. Almost as much as I drink and post.
  14. I noticed that too. But the blue roll cage bars are there. It has a Rebello motor. It's funny how these guys just don't know how important the sound of the engine is. Nobody watches a race car video for the music. Thousands probably left on the table. You'd think they'd watch a few auctions and figure it out.
  15. Mounted it to the condenser brackets. Should be fairly hidden once the grille is in and the car on level ground
  16. Direction... If you replace it, you have to source the part - done Cut it off realign, weld, grind and limit distortion If you repair it, you have to pull, beat and reshape it back to where it should be but all the metal is there in the close to proper amounts. One concern is if the car took that big of a shot then the whole side of the engine bay could be off. Then you cut and patch it but the repaired section is still not in the right place. My car was put on a frame rack and needed some significant pulling to get back to where it needed to be
  17. Some spirit levels have a barrel shaped glass, rather than curved. That way, the level can be used on top of, underneath, or beside the object being checked.

    OK. I've got a whole F54 setup here... Block, crank, caps... But the block block casting itself is no good*, so I don't mind selling the caps off separately. The crank is also available to a new home if anyone is interested (shipping prohibitive). *There was an ummm.... mishap during the rebuild process. I believe the technical term is "oopsie".

    "News" programs are TV shows, funded by commercial interests, designed to get people to buy things. Whatever keeps the consumer amped up and buying is what the producers want. CO's post was a good one, but, of course, you have to ask who put the plot together. Another group selling news. Question everything. https://www.adfontesmedia.com/ https://en.wikipedia.org/wiki/Ad_Fontes_Media

    CNN is surely further left than that chart shows. They and MSNBC are unwatchable for me. Not news. All leftist opinion.

    Personally, I hope you stay and continue to post.
