THe search isn't working right now... But my question is... Has anyone doubled up the OEM HONDA head Gasket to lower compression? Does it work? What were the pros and cons... ETC... The reason for the question is.. My wife has a JDM D15B VTEC and the compression is a little to high for boost and we want to lower it a bit... TIA

if its a stock d15b
its not high in compression you be fine

as for doubling up on headgasket.. dont even think about it

I thought the JDM D15b VTEC had high compression... That's how it made 130HP ... Is that wrong?

 

9.6:1 is the compression

 

WHAT??? Really??? How does it make 130 then? And what's the comp. of the USDM D15B7?

 

9.2

they arnt even the same motor

 

ya you can boost on high compression to you can just run more boost with lower compression

 

Can run a fairly decient ammount of boost on stock d series. They dont have near high compression as a b16a or b18c. With a diet of 100+ octane gas and some good tuning, your safe up to about 190~ whp

After that, stronger rods and forged pistons are almost a must.

 

no, not true. people have made 220+ on pump gas....the weak link is the rods

 

doubling up the gasket i would say may create a problem, why not just get a aftermarket head gasket to lower compression? and with higher compression your hp goals will be easier met with lower boost, and high boost and lower compression

 

I'm thinking about getting a thicker gasket but was just wondering if anyone had doubled up...

 

gotta remember timing belt a real thick head gasket COULD cause issues with this

how is that? its not like he is using a 1" thick head gasket, but you will blow the head gaskets easier if you double them up

Just get a thicker gasket if you feel like you have to. You'll probably be thankful that you did.

imagine using a 1 inch thick headgasket....do you think the timing belt would even string?

same concept but on a smaller scale. the timing belt will still string but there's a small chance that it'll stretch and jump a tooth etc
