Just curious as to how much boost a stock head gasket on an s52 motor can handle? I am about to purchase a stage 1 supercharger and only plan on running like 8lbs of boost. Nothing crazy. It's only a weekend car. I just don't want to go through the hastle of replacing the head gasket. Thanks in advance.

You'll be fine, just get arp (or arp2000) head studs and you are golden. Preventing blown hg's on m/s5x type motors is all about preventing cylinder head lift with copper, MLS, or even stock. -
if you have the motor pulled and you are going to be replacing the studs, would it be beneficial to go with an MLS because you're already there or just stay stock?1989 E30 Zinnoberrot Vert 325i OBD1 S52 turbo;IPComment

Cometic MLS and ARP studs.
If you're going FI that is the best way to keep things together aside from o-ringing the head.sigpic

Do most guys O-ring the head or the block? I thought it was usually the block that got it.Originally posted by JTapper View Post

Traditionally the block I'm told, within the tuner circle the head seems to be more common... I think the head o-ringing started with cast block/al heads and their different expansion rates etc. My head is o-ringed, not my block, for this very reasoning.Originally posted by Adrian_Visser View PostComment
