im thinking to drop my b18c1 compression ratio to 9:1 , i just wondering whether u guys can tell me the thickness of a headgasket i should get .
thanks

 

you should call in line pro @ 703-644-1788. they're in virginia and they do mail order. they're headgasket drops a stock b18c1 to about 9.2:1. they know their **** regarding head gaskets. ask for stan or john lee. i run one and i love it.

 

I agree, I used to have an inline pro headgasket and it was the ****.
good luck,
Jared

 

How much is a inline pro head gasket for a b18c1?

 

they are $299 plus shipping. they usually ship out within 3 days of order.
703-644-1788

 

how much boost do u run to get that amount of hp?
i thought that stock map sensor only reads to 11 psi
what kind of fuel are u running?
how hard is it to install a head gasket
i am contemplating an inlinepro gasket
thaks

 

you can run up to 22 lbs of boost on a stock block using the head gasket. this can net a stock gsr engine with no stand alone almost 400 hsp. we run 116-118 octane gas. you need a fmu, injectors, fuel pump, cam gears, and an afc. installing the head gasket is as easy as installing a stock one. call 703-644-1788 and ask for stan.

 

What would my compression drop down to if have usdm type R pistons and a milled head?
(around 10.8:1-11:1)

In the future I want to go turbo with around 10lbs, then I'll do it right with the bottom end built.

 

check your im.
