I have a b18c1 at 10 psi and hondata with 300whp. I blew my headgasket yesterday and will be replacing it myself in a few weeks. I am going to get arp head studs. What I want to know is should I get the OEM or Cometic head gasket? And should I buy a thicker hg to lower my compression? Will I need to retune my ECU after that change? Thanks

 

Leave it stock, and find a better tuner.

 

Either or doesnt hurt to do. Make sure when you head gasket blew that it didnt overheat or warp your head. But im sure it didnt. Find out your cause for the blown gasket cause 300whp on GSR shouldnt be happening.

*shameless plug -- we're having sales on Golden Eagle, Cometic, ARP combos'

 

I have been driving it at 7 psi with a fmu for a year and then another year and 2 months at 10psi with Hondata. I just figured it was getting worn out????

 

Head gaskets dont really "wear out"

Either temps got hot or your head lifted

Plus depending where your from and right now other than Alaska, its pretty hot around.

 

It has never overheated but the weather has been close to 100 in the past two months. By worn out I meant that the head bolts are stretching.

 

About my initial question, should I replace my head gasket with a thicker one to lower compression or is that not nessecary?

 

just buy an oem gasket and get some arp's

 

IMO, not necessary. You can always run a conservative tune.

My headgasket went cuz I overheated the engine at the track. Corrected the problem with a better radiator. Replaced my gasket with oem, added some arp studs and it's been runnin' strong since.

Does everyone agrre that OEM hg and stock compression is the way to go?

 

No reason to lower the compression if the motor is running ok with no detonation, and if you have no plans to turn up the boost. OEM

 

agreed that arps are in order.

 

OK, I will be keeping the factory 10:1 c/r but which brand should I use, the OEM or Cometic?

 

OEM, cometic gaskets are overpriced and suck ***

 

I just ordered a cosmetic gasket i hope my withstands the 20+ boost im throwing at it

 

Anybody else have a preference?

 

dude. oem gasket... arp headstuds and be done with it

LOL think he got the point?

agreed with this man.

 

I get his point but I wanted other peoples opinion. Thread closed. Thanks everyone

 

fyi,
incase no one mentioned it,
you would have to retune if you change your compression

 

I only use aftermarket headgaskets if I am raising/lowering the compression, or changing the bore size...

 

i only use OEM. im making 360whp and have ARP's and OEM head gasket.

I live in wichita KS, their is one dyno in town and it is owned by MODIFYD who also tuned it. Where else can I go to get it tuned?

A blown headgasket is a damn good sign that the motor is detonating and he just can't hear it though.
