Just like the title states. I thought Mike (boomin) used an S60R headgasket on his 2.3l during his build. Wondering if this is confirmed to work. My reasoning is i believe it will hold more boost.

If it doesn't work what are the guys running 20 lbs + using for a Head Gasket?

I was under the impression that the stock OEM gasket is good enough for that kind of pressure.

Headgasket and holding more boost ?

I used stock headgasket, copper headgasket spray with arp head studs and held 21 psi in first and 2_ whatever psi i wanted in second, third, etc. . .

but then again i was probably the only one running a 16 psi wastegate (minimum boost) among everyone

I used an ELWIS royal set which is OEM equivalent in my build and run 18 -20 all day long without any HG issues. I did burn an exhaust valve, but that’s another story. When I removed the head I couldn’t have asked for a better seal.

this topic has been started a lot (once by me). and yes, some have ran a s60r gasket on 2.3, but the high HP guys agreed that a stock 2.3 Hg was plenty.

thread? If the 850 one would have fit on the s60r then there must have been a reason volvo redesigned it hence why i want to use it.

Coolant passageways changed in '00 iirc.

John, stick with the OEM HG for your engine.

Thanks for the help!

anyways I found this thread here and it basically explains the S60R is 3 ply so it will lower the CR = bad for performance. It will hold more performance wise since its 3 ply but I really only want this engine to last 6 months so i'll go the safe route and when I do my build I'll use the S60R gasket

[randomdude]

with a lower CR you can run more boost, which isnt always bad for performance.

and i think ozzi hit it on the head.

but either one is fine.

Exactly but with this motor I plan on leaving it where it is ~20 psi and then slowly build up another motor with forged internals ect, that motor will get the s60R head gasket

Why not get the complete solid lifter head? Its what I have for my build.

I'd argue the S60 gasket will hold less HP on an 850. CR its not going to make any difference. You will loose way way more CR when you clean up the chambers. You just measure before and after and adjust the piston dish to compensate.

Why is that? I'd imagine a thicker gasket would be able to handle more stress? Just wondering your thoughts on it now, my build is a long way off

Its thinner at some key points which is secondary, but you kinda hit it on the head. Its thicker. Thicker gasket = more surface area. If you are that worried about replacing the HG o-ring the block.

Just the block. No point in doing th head also. Should be pics up if not I will dig some out.

Thread revival engage!!

Chuck, what is your argument for the use of the newer R head gasket?
