Which would you choose and why?

[Aproductions]

So if you were building your car and only had:

93 octane
50-50 meth
Holset turbo and wanted around 25lbs
Ecuflash and evoscan to tune
Build motor

And were using a .020 Cometic MLS headgasket.

What compression would you pick and why?

8.6:1 = .075 thick

8.8 = .070 thick

I prefer to use a thinner gasket, as there is less force that can be exerted on in.

What holset turbo? The bigger, the more pump gas freindly obviously. I see no reason at all why a properly tuned motor would have issue at 8.8 w/ meth. Stocks 8.5 of the 2gs.

My votes for 8.8:1

Thanks, and well you see, I can't go thinner because then my compression will be too high.

But I should be safe with the .070 thick gasket right? I am using a MLS and ARP's

 

[sniver]

You will be fine with the that setup.

I would run 8.8 CR.

 

[Aproductions]

I just dont wanna not be able to run the amount of boost I want and have tuning issuues and at the same time I don't know what is too thick of a MLS

How far out of the deck to the pistons protrude? Your going to induce det. with a .070 quench...

What pistons are you using?

 

[Aproductions]

I am using the 9:1 manley platinum pistons.

the block and head got decked for a MLS and now I need a .070 for 8.8:1 comp.

is that okay?

 

[Aproductions]

is that too much quench for a eclipse?

what could I do?
