  1. AFrench Blue '69 GTV Restoration

    GT (1963-1977)
    Amen Im fed up listening to the self professed experts and their pontificating on the alignment of the planets and their relationship to Alfa Romeo's. Do your homework, then do it yourself is the only guarantee that it will be done right. Happy Motoring b :cool:
  2. New Source for 4340 Rods

    Engine Repair, Diagnostics & Rebuilding
    "In closing, I can't qualify manufacturers' claims that these Asian rods are good for 9krpm/1000hp and I doubt anyone will be exploring this area with 2liter Alfas anyway!" There's an old saying that's applicable here: "There's a sucker born every minute" (P.T. Barnum).
  3. New Source for 4340 Rods

    Engine Repair, Diagnostics & Rebuilding
    Sure, the small companies are all forced to get the ISO 9001 manufacturing certification and keep it current, because their customers all demand it and will send in Auditors like me on a regular basis to make sure they are complying to all their processes and published manufacturing standards...
  4. New Source for 4340 Rods

    Engine Repair, Diagnostics & Rebuilding
    "Rod bolts are not Chinese, they are ARP 2000 in all comparable ads. Maybe they figured there's no financial sense in also making those. After all, I would think the big profit comes from the rod itself. Not being an ASTM-accredited auditor, I can't answer your points as to mat'l/process...
  5. New Source for 4340 Rods

    Engine Repair, Diagnostics & Rebuilding
    "The often used argument about 'cheap Chinese stuff' doesn't hold any water here. Look at it another way: if the supplier really offered substandard crappy parts, how long do you think it would take for the first blown engine bad news to travel the net? Light speed? You can bet on it and that...
  6. Connecting Rod

    Engine Repair, Diagnostics & Rebuilding
    Paul is not selling the Marine Crankshaft. He's got a vendor in North Carolina (I believe) that makes them. BTW: He has his crankshafts made with the stock oil passages so you don't have to modify the block to oil #2 and #3 mains directly. The downside to that is its almost the same weight as...
  7. Connecting Rod

    Engine Repair, Diagnostics & Rebuilding
    I agree with Gordon and have done the same thing with my engine: Carrillo rods, Marine Crank, lightened CP Pistons, accusump, Mocal oil cooler, crank girdle, everything that can be done to the bottom end to keep it from going Ka-Blamo. Ive seen a lot of race engines throwing primarily the #2 rod...
  8. gear noise after R&R pinion seal

    Spider - 105 & 115 Series (1966-1994)
    Richard, I like the bananas idea, I might try that.! b :cool:
  9. gear noise after R&R pinion seal

    Spider - 105 & 115 Series (1966-1994)
    OK RJ I hear what your saying, but then why only on deceleration.? And of course why all of a sudden and only with this motor. Ive had other motors in front of this diff, no problems. BTW: I made an appointment with a dyno shop next week to make good on my promise. B :cool:
  10. gear noise after R&R pinion seal

    Spider - 105 & 115 Series (1966-1994)
    Interesting: I should check the BB more often. To that end, I changed the pinion seal 20 years ago when I installed a late model LS differential in the Duetto after twisting off both axles on the original with a motor that made exponentially more power. Right: the diff I installed was a warranty...
  11. Fuel pressure problem on a 67 Duetto

    Carburetors, Fuel Injection & Air Intake
    When I start the car cold I get really good fuel pressure (3 psi): (FYI) I have a digital Auto Meter fuel pressure gauge sending unit installed in front of the carburetors monitoring the line pressure. OK, Ill drive around (it takes awhile) and all of a sudden the fuel pressure starts to drop...
  12. OS Giken GTA Close ratio gear set

    Gearbox, Transaxle, Differential & Propshaft
    :smile2: They build a lot of cars in Mexico, VW has a huge plant there, So Im sure the infrastructure exists to manufacture quality parts. Its all about the design, material selection, secondary operations, manufacturing process control documentation, initial and AQL level quality inspection and...
  13. OS Giken GTA Close ratio gear set

    Gearbox, Transaxle, Differential & Propshaft
    Folklore has it that OSG had some issues with its secondary operations. And as a result some gear sets had quality issues. Of course any and all of this could have been avoided by implementing proper Mil Spec process controls and AQL level quality controls. It always amazes me that manufacturers...
  14. OS Giken GTA Close ratio gear set

    Gearbox, Transaxle, Differential & Propshaft
    9-15-2015, year 4 UPDATE: The OSG gearbox is behind its second engine and it still shifts like a dream. BTW: engine #2 is a monster 2 liter and the OSG CR gearset is definitely taking a licking and it just keep right on ticking.! Happy Motoring b :cool:

  17. How to choose different intake and exhaust cams?

    Engine Repair, Diagnostics & Rebuilding
    Engine design 101 was interesting but really didn't talk to any of the design secrets of how ECR gets to better efficiencies of scale. Other than the discussion about squish at the end of the lecture and basics of horsepower loss from various components of which piston to wall friction always...
  18. Biggest possible overbore in a 1600 Nord engine ?

    Engine Repair, Diagnostics & Rebuilding
    Titanium Valves I had Ferrea make some custom stainless valves with 8mm stems for me. The intake valves are 46mm and are 20% lighter than stock and the exhaust valves are 38mm and 27% lighter than stock. The weight of the intake valve is not that critical, its all about the exhaust valve...
