I noticed that a lot of people upgrade their head studs with ARP but don't hear too much talk about upgrading their main studs. My motor is apart and was just going to re-use the stock main studs and upgrade the head studs. Would it be wise to upgrade the main studs as well, or would I be okay re-using the stock ones? I never plan to make more than 800rwhp.

Im a tech at a Toyota dealer and I have rebuit a ton of motors. Each time I reuse the stock heads bolts or studs. They are a stretch to yield and Toyota says a one time use only. But you can reuse them a second time and you would be fine. In your case i would just upgrade now while you have it apart.

While you have it apart spend the Money and do it right. In this situation Peace of Mind for the right parts wont come even close to breaking the bank. NEVER reuse TTY Bolts. The TSRM says dont do it and it is the Bible for the Supra.

For peace of mind I'd upgrade it. Cost is small but if the bolts fail, the consequences are catastrophic.

The rule of thumb is to replace them for any vehicle. Some manuals say it's ok to torque them down twice but I never risk it.

One reason i would never let a shop work on my car
