My set up is B16a with CTR piston. I've been searching about the headgasket and i can't get a straight answer. I want to raise the compression a little bit higher so should i go with a spoon head gasket or OEM gasket and remove one layer? Removing one laying of OEM head gasket... is that safe?

 

Y would u wanna remove one layer for, if any thing u stack them. u should get inline pro head gasket , there good

The post is about OEM head gasket being safe with only two layer or Spoon head gasket, not inline pro. You didn't even state if inline pro head gasket would raise my compression. Anyone else who knows more about this?

Thinner head gasket = higher compression (that's why)

 

I wouldn't want to tamper with removing layers of the oem headgasket. If you want higher compression dish out the cash for a Spoon headgasket or something similar.

just my .02

 

Many people modify an OEM gasket and don't experience any problems. However, I always suggest an actual 2-layer gasket such as the one offered by Mugen. It isn't all that much more expensive than an OEM gasket, and it was designed specifically to function correctly as a 2-layer piece. In all likelihood, you won't have any issues regardless of which option you select, but since pulling a head isn't a terribly quick job, I just prefer to go with the Mugen gasket for additional peace of mind.

 

Just take your head off, get it milled, and put it back on with an OEM gasket!

 

mugen head gasket raises compression by .04

 

for those that don't know...spoon's 2-layer B-series gasket IS an OEM honda B-series without the middle layer

mugen's was specifically designed to be 2-layer..... which is why I am getting mugen's gasket for K20a

 

mugen... I had that on my b16 with ctr pistons.... good little setup

Indeed, and in fact, all the information I've seen indicates that the gain is actually closer to +0.3:1 for the Mugen gasket.

The information you provided is what Mugen itself claims, so you can't be faulted for that. The 0.3:1 number is something that has been suggested by several individuals here on H-T, though I have not seen any 100% concrete evidence to support either figure. Of course, the difference is small, so it is basically a moot point either way.

 

Im runnin' a 92cx hatch, b16 with CTR pistons and a mugen head gasket... runs great. People claimed the compression would be "a little high for street driving" but I don't mind it at all. It's been almost 10k mi. since the build and it's still running strong.

 

A little off the topic does anyone know how high of compression you can go without detonation using 91 octane?

what are you talking about......I can replace the head gasket on a D in less than 40 minutes and I can replace a head gasket on a B in less than 50-60 minutes.

it is extremely simple mang

 

Thanks for all the response. I looked up the spoon and mugen gasket on inlinefour.com. Compared to each other, the Spoon measured to .45mm and the mugen gasket measured .47. So im guessing if i want more compression, i'll go with the Spoon .45mm. Thanks for all the replys!

The difference is nominal, but I prefer the Mugen gasket because it seems to have been used by the most people with the greatest success, and as mentioned above, it is a purpose made 2-layer gasket.

SPOON = more compression yes? less reliability - most likely than Mugen
