has any one used the cosworth 1.3mm hg operating over 40psi??? feedback???

 

use OEM...... why bother with cosworth? Talk to headgames since they designed your head. Stock HG is very good on evo.

 

Thanks , I'm aware of the quality of the mls gasket ... but still need feedback on the cosworth gasket, that's what's on the car.... anyone with feedback would be great, thanks...

 

46psi on 6765 on mines.

 

holy crap. what are you making like 950whp?

 

Nice to hear, no problems obviously? What head studs/torque specs?

More feedback is welcome

 

I run arp L19 @ 100tq with moly lube. when tightening its good to do like 30 60 then 100. no need to go more then 3 series.

 

How bout you omniprobe?

 

For the price of and OEM why not get a cosy?? their about the same, i have one....isn't on the car yet though.

 

5 bar sensor, buried, stock head gasket. I have a hard time believing the hype that was written on the Cosworth gasket when the guy who wrote it can't keep a head gasket on the EVO he is involved with.

I'll take the Mitsubishi gasket.

 

OEM headgasket is all you need

 

Can't argue with that .... but the fact of the matter is it IS a cosworth gasket on the car and I'm not gunna pull it off the thing is pushing coolant (which may be sooner then later the way everyone speaks about it)

Dave , any personal experience with the cossie gasket going bad?

Had a oem mls on there pushing cylinder pressure to the cooling system... decked head / checked block and installed the cosworth gasket.... fml, the project never ends!

 

what head studs are you using?

 

Ams L19's, torqued to 90ft lbs. Stepped up , 70,80,90....

 

i'm using MAPerformance ultimate L19/H11 studs, they say torque to 105ftlbs
