To O ring or not to O ring Hi guys and girls.
My old man is building a twin turbo 427 GM performance LSX motor for our ( monaro ) your ( GTO ).
The question is we want to build it for about 20psi max boost.
Should we get it O-ringed just to be safe or do we just use cometic MLS steel shim type head gaskets?
Engine parts so far.
GMPP LSX Block
GMPP LSX Heads ( 65cc chambers )
Dragon slayer crank
wiseco pistons.( dummied up at .020 down the bore)
FULL ARP STUDS in all holes top and bottom lol.........
SO SHOULD WE O/RING OR NOT O/RING????????????????
For thos that have boosted one of these things ? have you had any problems so far?
Any help would be great what are your thoughts??????
Thanks in advance regards Paul cheers

Go O-ring. You say max 20psi now but in a few month you'll be saying more. My policy is: always build your drivetrain to take 1.5-2X the power originally plan on. I've been through several of my own FI builds and those are my words of wisdom.

at least get them to upsize the exhaust housing ARs on those turbos or you'll be chocking / falling over at the top end.
And while your at it get a bigger intercooler 600x300x100.
Muilti layer steel gaskets should be fine.
