hi guys. this is my first time posting here. i'm building my frinds b18 for turbo and now i can't find any spec for APR studs. are the torque specs same as factory head bolts? i also need to know the way to tighten them up. i looked at aldata but couldn't find anything about it. i also would like to know how much power the stock non sleeved block can handle. thanks

With ARP, if you are turbo, take them to 80. One time use, however. But your HG won't leak.

also B18 is too specific. you could be referring to something from from a 120 hp B18A to the JDM B18C Spec R...

 

ARP recommends 70 ft/lbs

I take it to 75 ft/lbs... on every motor I've built, seen over 700whp on them.. no problem.

 

it's b18 c spec R, but isn't 700hp out of stock cylinder a little too high? i heard close to 500 is the max before cranking the cylinder walls.
