Is it possible to lower the compression down to 9.01-9.5.1 using a thicker headgasket on a b16a2 and would it be practical for around 320whp because id rather not mess with pistons and rods until next year in the meantime i can concentrate on the tuning side hondata etc, im gonna be running a t3/t4e .60 trim and hoping for around 300whp at around 15psi

If it is possible what headgasket will take me there?? anyone tried it whats your experiences??

No personal experience, but have seen it done plenty of times...

Yes. This approach has been done before..

 

hmm so it is an option tempting, the question is how much power will i be able to run with this setup and what gasket will get me there.
any experiences etc
thanks

 

any experiences with lowering compression with headgaskets?

 

roflmao 300 dollars for a head gasket. THats jus ******* stupid.

considering the center section is re useable its not too bad..The setup works well. I used to run it. Quite a few stock motors making 350-400whp with it.

 

if you just run 12-13 psi on stock headgasket tuned you should be close to the same power level as 15psi with the thicker headgasket... just the tq #'s wont be there, correct?

The power loss you see going from 10.2:1 to 9:1 is not going to be as great as 2 or 3 pounds of boost.

 

I would be very surpised if a head gasket alone could bring it down from 10.2 to 9.. i was thinking more along the lines of 9.5:1.

2mm will drop it a full point

 

what about the time belt, when putting on those thick head gaskets?

 

you have to make up for it with cam gears...Usually advancing the intake and exhaust cams 2 deg works.

 

maybe a stupid question ....but how thick is a stock ITR b18C6 headgasket ?

A 2MM headgasket will take a B16 to 9:1 compression. A 3MM gasket will take it to 8.25:1.

 

where can i get a 2mm headgasket or is it possible to use 2 oem headgaskets??
how much power will stock internals last with lowering compression like this??
any experienced ppl anybody else tried it

 

my motor has been together for about a year @ 315whp on pump gas. You could prolly safely push 350-375 on race gas.

what gasket/s u running? whats your setup

 

Inline pro 2mm gasket and ARP's. I sold the car a month ago..

 

Completely stock head and bottom end?

umm....i painted the block

 

thats interesting i may use this method temoprarily until i dont get pistons etc

 

any more experiences with this

 

which is better the cometic or the inlinepro?

 

from what i was told, the cometics now only drop the comp about .2 or .3 points, they used to make a 2mm gasket but don't anymore.
