  1. It will have been metal fatigue that will have killed the rod. They're a pretty light rod, so the rod bolts wont have been tugged to death. I expect the endless dorting to infinity will have been enough to induce the failure.
  2. The formula for max piston speed can be found here, http://www3.sympatico.ca/big-d/polytek.htm Disclaimer, this page is just something I found on the net in the mid 2000s. Beyond that I cant vouch for accuracy etc
  3. I had an engine where a piston broke. Based on the galling in what was left of the pin bore, it actually looked like the pin may have seized prior to the piston disintegrating. Theres a rule of thumb for maximum piston speed before forged pistons are required.
  4. Most of the smaller superchargers just run PK belts. They're all that's needed tbh. Also, Have you considered supercharging it? An SC14 on a 1500cc engine yielded ~11psi for my bad self. With EFI and an Intercooler (water to air would go good) your little imp would embarrass some much heftier cars....
  5. Take give a little donations to build a 1500cc motor that wont pop. (After the 1300 lark)
  6. So that's a yes. Over half of that book was about making the head work properly.
  7. Are you going to fill in the floor of the intake ports Dan? Vizards book about making these motors breath say the floors of the ports are dead space. Pretty sure @nismo.capri filled the floor on his old Van's head. (That thing was quite jolly peppy too!) He reckoned his head out flowed the one in the book too. (Not that any two flowbenches will read the same)
  8. I'd quite like to sink a beer with your bad self Mr Ned. (I'm filled with regret I cant attend sausage fest this weekend coming) if you know where you're staying, hola atcha boi and we can try link up.
  9. If its picked up at the time of vin inspection, budget ~$500(?) For a repair cert, plus the cost of any extra work required to satisfy the repair certifyer that its bedn done right. (Possible strip down etc)
  10. Have killed a motor or two, I can relate to your present situation. In my case, the car was sent to the naughty corner until I could muster the $$$/fucks to start again. In your case, option B is take donations from willing people. Even if just to score another stock bottom end to see your car back on the road in only 1 weekend. (Assuming it's not raining) this thread is more entertaining than sky TV. I'd chip in $30 happily. It really feels like we all share in your success. And every blown engine is a learning experience/scars have the power to remind us that the past was real........
  11. Yeah, I'm with Bevan. This thing was turbofucked. If you can fix this, you can fix anything..............
  12. I have nothing of value to add except that someone who did a lot of research also concurred escort was the best.
  13. Thinking about your thread update today, You say it doesnt drive real nice at 100kph? Weren't these a sports car of sorts? Is there a reason why it doesn't have the nimble cat like road holding?
  14. Good on you for persevering. Sometimes you need to put a car in the naughty corner until you can muster the fucks needed to press on with it again.
  15. Was your rig sold in 'murica? Try rock auto?
  16. Depending on what date I might be persuaded. Could be my swansong for this ride.
  17. Some diffs require a casing spreader to get the carrier back in.
  18. Clearly the answer is a Barra swap.
  19. @85_z31 made an adjustable rear set up for his z31. There's probably a thread for it at nzdatsun.com. (I doubt hes been here in a long time?) James is a super smart cookie too. (I dont recall exactly what he did tbh, but he did help Greg ( @datto_610) design and build his set up.
  20. Given the huge revs that doritos can do, youd wanna be mindful of your tail shaft speed.
  21. The later ones were a massive improvement then!
  22. I thought these things had a BW35 auto trans? If so, its definitely been rebuilt. Even behind a rover engine its sure to have fucked out by now. Another thoroughly enjoyable thread. Your build threads 100% make up for your taste in cars. Such satisfying read.
  23. I almost got burned once, so I never let a car go until the change is completed.
