when putting my motor back together, do I really need to use ARP head studs to bolt down the head?
I know studs are supposed to stretch when you torque the head and that is why its advisable to get new head studs...
If I use the original ones from the motor, does this mean they could break while assembling the motor again - more fragile?
They don't just break. You could re-use them, but make sure of the tightening sequence and the gradual tightening procedure.
New OEM will go a long way. Unless you're boosting 1.5 bar or so I doubt ARP's are necessary.
depends on the motor you have...
CA18's dont use stretch bolts and they can be re-used.
SR20's have a stretch limit - so they can be re-used if they are not beyond the limit...
however - keep in mind the boost you will be running (like Dr G said) - the above recommendations are for stock boost, not big boost!
Thanks for the info... didn't know that ca18 didn't use stretch bolts...
I think then I will use the originals, and I can spend that $$$ on other much needed improvements
It depends... I got ARP in my CA, but then again my intentions with the motor is a bit different... it was built to handle +1bar boost... to make some good power, which neither is happening 😂
So all in all... Nah you don't need them, you can rather go buy new stock ones like ChemCool did, wasn't expensive IIRC.
