i have searched and found nothing on this. i blew the hg last night while tuning. i need to know what good hg i can get to lower compresion some. my set up is a stock gsr hatch with peakboost turbo kit and my goal is minimum of 300hp with a conservative tune. thanks for the help

 

Why do you want to lower your compression if your just trying to get 300hp? Can't go wrong with a OEM head gasket with ARP head studs

 

just get an oem headgasket....not the ones from parts store

felpro MLS gaskets are just as good as OEM.

my buddy uses the felpro's, but I don't trust them.......just my preferance. Plus I get the OEM ones for cheap

 

OEM + ARP's would be my choice...that's what i'm using on my 450whp build

 

ARP Head Studs, OEM copper sprayed headgasket.

Yup. That's what I run...

 

well when i pulled my head i saw cylinders 1 2 3 were cracked so ill be starting a 450hp project and i will be using the oem hg with copper. thanks

 

Cometic or OEM on everything we do

 

I made 505whp and 360ft pound tq. using OEM honda head Gasket and ARP headstuds!

OEM works best IMO!

 

oh and arp headstuds

Ouch!! Who tuned that time-bomb??

 

i really dont want to say who tuned it but the motor was stock and i didnt know how many miles it had. so i dont know if it was their fault or it was that the motor was already weak. let me know what you think. thanks

 

If you would have cracked one sleeve, we could call it a fluke or a bad injector. Two sleeves would have been a little fishy, but all three makes me think that there was something fatally wrong with the tune. I honestly couldn't think of much else that would have let to such a catastrophic failure other than overall fuel cut to the whole engine. I have a feeling that the timing was a little aggressive and the AFR's a little lean....

 

for all you know, he could have had a bad tank of gas.. or just run it out of gas in general.

Thats true too...there are a few things that could have caused the problems, but i would still investigate the tune a little bit before attributing it to something else.

 

and thats the problem with people these days, they dont know the 1st damn thing about their car... if they did, they probably wouldnt have blown their **** up in the 1st place....

the headgasket is the least of this guys worries.....

 

i knew this was going to happen. i knew this motor was not going to last long. thats why i had bought a ge block that i was going to build up little by little, but i guess now im gonna have to build it asap. lol. your right i didnt know anything about my car as i am not mechnically inclined. i have a very good mechanic that knows all this stuff like the palm of his hand. its all fun though when you get into this hobby you know that stuff like this can happen. im not worry about it like i said before ill have a 450hp dd sooner than i thought. its all fun.

 

post pics of the bottom end

 

yeah im going to post pics as soon as i get the motor out. i had just pulled the head. i still got to take it out of the car and as soon as i do that all post pics of everything.

 

it doesnt matter how good your mechanic is......ignorance can ruin anything

 

I can't say enough about the OEM head gasket. I used the original head gasket on a motor with 80k and put in ARP head studs one at a time and the motor made 375whp, of course I was when it saw boost for the first time, but it held up fine.

 

come on guys he said he wants a minimum of 300, i say use a cometic .050" HG, that will drop you down to 9.5 which is perfect imo. ive had boosted high and low compression set ups and i must say i prefer the lower compression set ups, currently 8.3:1 right now on 91 octane 333whp and im not even close to the limit, and thats on cast pistons and stock rods...

 

whats your point... we have a car making 390 to the tires on a bonestock ls bottom/bone stock b16 head oh yea,, stock head gasket too !
