One of the best, setups.

A. get a Either Mits. MLS, or Cometic for highpower, personally ive ran 24psi on a mls befoore it popped on a friends tsi. Anyway ARP head studs equal worth it. Also i swear buy a new timing belt from a mitsubishi dealer, always stronger than parts stores.

mls??

Multilayered steel gasket.

May I suggest that you read the threads guys have written about MLS and SGE gasket problems. There is a big debate about whether or not to use copper spray sealant on MLS gaskets. I just installed one in my 350 HP fwd project car without sealant and have not yet road tested it. Apparently they can "push" coolant under boost over 15 psi. I am not sure what they mean by "push", but I am a little worried. I am waiting to buy DSM-Link V3 so I can fine tune my engine. Hope to get it tuned by winter. I'll post back and let you know how the MLS gasket worked out. By the way, I installed Mahle pistons with 0.0015" piston sidewall to cylinder tolerance!!! Eagle rods, stock crank, Stage 5 head, 16G, 3" exhaust all the way and she fired up first crank. It was a religious experience. I have sunk uncountable thousands of dollars into the thing so far. I am using the cyclone intake so I can eake a little more low end torque out of it. COP ignition with my own IGBT igniter circuit.
Revs up to 3500 rpm lickity split. Have Stage 2 kevlar clutch and lighweight flywheel. Runs rich so I can't road test it yet.

What piston to wall clearance did the spec sheet that came with the pistons say to run? .0015" is awful tight for forged pistons.

500whp? since you have a 6bolt (thicker head bolt holes), all you need is a stock composite and arp headstuds. They've gone over 100whp more than your goal very frequently.

Fel-pro MLS and some L19s. Yes it is a little over kill but you will not have to think about it again.

 

[dsmfa9nutter]

Any mls and head studs. I have never heard of mls gaskets pushing coolant, and doing so at 15psi is just silly.

Then you have been hiding under a rock for the last 10years

 

[codeofdastreets]

So a mls wit coppers spray should do the job?????

 

[nlzn]

Mistu MLS and ARP's here.

Daily driven @ 18lbs.

Has seen over 30lbs.

Does not push coolant and I did not use spray. Had both surfaces measured and milled before install.

As Brian and I have said, so will ARPs and a composite. . .

 

[dsm-onster]

Yes you have to take your time and a bit of money every time you install your MLS headgasket. I'm not one that likes to wait for a good machine shop to get to my head for a resurface and do all the prep work on the block. Is it a waste of money and time, when a simple composite gasket and ARP head bolts have held more than 600whp on daily driver cars? I think so. But I can understand someone wanting to overbuild. But it's like buying forged internals for a 6bolt when you're never going over 500whp. . .

Im rockin a Cometic and some ARP's boostin steady 25lbs with a Holset and have had no probs

Oh if I only knew that 2 years ago. I could have saved thousands on my fully built motor that's running an 18g. I swear I'll get a Holset one day and put it to good use!

Follow what the wiseman sayeth.

I use a Stock OEM mitsu Composite gasket but the Stock Mitsu MLS (part number MD349347) is good also. However you have to MAKE SURE that the sealing surfaces are machined PERFECTLY smooth. The HEAD and BLOCK must be machined for a good seal with MLS

A Composite is NOT as hard to seal up as the MLS. And with ARP's the composite can hold 575 hp reliably.

the surface for any MLS is very important,

what it should look like for an mls...
