  • Q: New OEM Shortblock  wRayth2 years ago

    Would these benefit with just a stock rebuild? Car was knocking so I purchased a new OEM block, however my Mechanic recommended to get these, Is there a difference between the lengths?
  • Q: Probably dumb  Mike8012 years ago

    Probably dumb but I’m currently in the middle of getting everything together for a frankenmotor ej25 and was hoping that you could tell me if these would work for said build? (Yes I read the other questions about the regular model fit but this is a bit irregular) pic of my ugly multi color gc because it gave me the option.

      A:  Without knowing the specifics of your build we cannot confirm fitment. We would recommend reaching out to one of our Customer Service Representatives in regards to your fitment question.

  • Q: Nuts  rhd_eli3 years ago

    These have new nuts pictured in the third picture if I’m not mistaken. I know the question has been asked, but it was also answered saying it only comes with what is pictured. So do they come with new nuts or not? And if not, where would one find new nuts for these?
    • 6 of 6 people found the following answer helpful

      A:  The answer, to end all answers, to end all speculation, TO BE THE BEARER OF TRUTH!! These do come with new nuts!

  • Q: What is the maximum engine HP these studs can be used safely?   Lagg-Alot3 years ago

    I have 430whp. I think I would be ok with these studs. But If I add more power in near future, what would you recommend is the highest whp before should I go with a stronger stud?
    • 0 of 0 people found the following answer helpful

      A:  Anything more and I would recommend going with the 625+.

      A:  Depends on cylinder pressure, look up user1029 on nasioc or iwsti, he made 570whp with IAG Stage 2 block and Stage V head using these bolts for over 60k miles without an issue. From what I understand boost pressure is more problem than whp. Consensus on the forums seems to be the max for these is 30psi.

  • Q: Fitment  turbomacncheese3 years ago

    Why does the fitment say they won't fit a Saab 92-x Aero, but they'll fit a 2006 WRX? Same engine...
  • Q: Head Studs  CSautoSVC3 years ago

  • Q: Torque specs?  dsfi10640615 years ago

    I was wondering what the torque specs are for these studs. I'm seeing different specs all over the internet. Some say not over 85 ft lbs and some say up to 95 ft lbs. I'm aware of the sequence, but what is the maximum torque value?
    • 0 of 0 people found the following answer helpful

      A:  Following the manufacturers recommended torque sequence, tighten the nuts in 3 equal steps to 90 ft lbs.

  • Q: HP strength?  NightwingSTI5 years ago

    compared to the custom age 625+ kit, what are differences in strength / hp capacity in this set? Looking for a max 400awhp build, with as much reliability as possible.
    • 0 of 0 people found the following answer helpful

      A:  The 625+ will have a higher tensile strength but there is no specific horsepower figure. For a 400whp build these standard studs should be plenty and I don't believe we have ever seen a failure in head studs at that power level.
