Im building engine to "customer" and he has 2 headgaskets. Ebay full set and cometic. If car would be my own id take OEM but this is now options. Its b16 with eagle crank, rods and SPR pistons or something. I have read so much problems with cometic so should i go with ebay gasket? Deck and head is going to milled so they are straight.

If options are these what is YOUR choise? If cometic is there any needs for that like copper spray?

 

throw the ebay one on just to teach the dumbass a lesson. i would go oem

 

oem

 

OEM even if you have a 83mm piston for example? how would that work since the stock bore is 81 for a gsr at least?

 

Golden eagle head gasket works awesome too. They also have diff bore sizes, but in your case i would take the cometic over the ebay, But oem ftw

 

Bore is 81.5mm.

 

it's cosmetic, not cometic.
goddamn all these kids that never finished high school.

 

last time i knew it was cometic

yes, and if your doing 81.50 bore, just do oem gasket. thats what im doing. and thats what everyone else mostly does and it works just fine. .50 mm is only .019".

 

wow, you're a dumb *** and just proved yourself as so. next time you try to call someone out like that, know wtf you're actually talking about. the company name IS cometic, not cosmetic.

 

I told him to sell ebay and cometic and ordered OEM. Get it tomorrow or wednesday when the block is ready. Its ~87 in usd here. How much is it in US ? I have used in my d16 dohc motor d16z6 OEM gasket and its 120 in USD here...

 

got it, thanks.

 

Good choice.

 

Agree!!!!

 

hahaha make up company...

anywho OEM is fine its bored otu bigger from the factory from the get go.

oh and a y8 gasket here is 23 bucks in thes states

 

Tell that to your pistons when they are sticking out of the hole...

 

sarcasm or lack of knowledge? stock oem gasket works fine with 81.50 bores. ask around.

 

Yes i have my d16 engine with 75.5mm bore, and have used 75mm and 76mm gaskets. Works fine. I dont know what kind of engine u got but if your pistons is coming out of block, i hope u have space there so it doest hit head lol

 

you forgot to mention what brand gasket is being sold on ebay.

a "ebay" head gasket makes no sense......ebay does not manufacture gaskets. the seller is selling a product on ebay. that product is made by someone.

 

It is possible to pwn yourself...I think it time to change my sig anyway

 

qft, last time i measured and OEM gasket it was actually 81.5mm, Honda does this to leave room for rebuilds etc and that way they don't have to make another HG for oversize etc... However OEM, Cometic, GE, all are good, i have used all with great success on cars from 250-630whp.

 

Sarcasm... Hence the :p

Either way when building motors .019" can more than make or break a motor... Ask around... :p

Also I sometimes forget to look which forum I am at and see it is the FI and not the N/A so I would hope you would not have to worry about some of the piston coming above the deck...

 

As blinx said above, he recalls that when he measured an oem gasket, it was 81.50. I even tested my new 81.50 je slugs and they fit through an oem gasket.

 

? Who was questioning you?

 

wonder if the JFdistributor HG is reliable??
