Hey guys,

I've heard that one benefit of the stock headgasket is it allows for a squishband, which helps the engine withstand knock. I've also heard that changing to a solid headgasket(ie: 2mm, 3mm) does away with that type of protection.

I was thinking....I think its SP stacks 2tt hg's and sells them that way, as an alternative to the 2mm and 3mm options.

Does stacking the 2 tt hg's allow for some squishband? Because if so that should allow for extra knock protection, right?

can anyone shed light on this?

thanks,
Bob

SP's stacked hg are 3mm. They are my #1 seller and work great.

ok cool, do you happen to know if they would provide the squish protection I'm talking about? I dont know how to describe it correctly but i knwo the stock NA HG has it...

Not 100% sure on this, let me give SP a call this afternoon since I have to order one anyways.

thats a really good point ure making, and the price for the two options is almost identical isnt it?

the 2mm and 3mm are not solid, they are both stacked.

Any of the thicker head gaskets mess up the squishband. It's the nature of the beast.

The word of god.

Any way have you installed that turbo yet? the one big enough to suck the a baby head in.

If you want the insurance then swap to TT pistons and use the TT headgasket.

Yet another reason I'm going to experiment with the stock HG and methanol injection. Factory squish and more low-end/mid-range 'engine power' before the turbo comes online.

Where can you get the methanol injection?

Do a quick search in the NA section and you'll see I started a whole thread about it.

2.0 or 3.0 mm headgasket?

If you're planning to run no more than 450rwhp, what's the point of running 3.0mm?
