I'm looking into buying either a Hondata or PasswordJDM intake mainfold gasket. the PasswordJDM is $10 cheaper plus free shipping. Other than price, are there any differences between the two? Hondata says theirs is plastic, whereas PasswordJDM says they use "special thermal material." Is the Hondata one really better or is it just the name? Upon initial inspection of the two, The Hondata gasket has less holes in the gasket, whereas the PasswordJDM has all the same holes as the stock gasket. Are those holes (or lack thereof) important? Do they help at all with emissions?

The hondata one blocks off the coolant port, right guys? I forget....

Either way, I'd just go with the cheaper one, its already such a small difference, it can't hurt....

 

Hondata:

PasswordJDM:

Stock:


The real question is, is blocking off the coolant to the manifold a good thing? $10 isn't that big of a difference to me, but is it worth it? My concern is the negative effects it may have. I'm sure Honda put those holes there for a reason... and if the Hondata one is effective BECAUSE of blocking off these ports, then what makes the PasswordJDM gasket better than stock?

Honda put the hole there so the engine warms up faster. If you don't care about this, get one w/o the hole. I'm running an AN-R one on my car, I chose the street version with the hole.

P.S. Special thermal material is plastic.

The car WILL NOT WARM UP FASTER with the hole there. The coolant goes to the idle controll valve. It makes the car idle higher when the car is cold. You will have to re-adjust your idle accordingly after you block it off. The whole point of the hondata gasket is to block the heat from the head and the coolant from warming up the manifold. If you were to let the hot coolant into the manifold you might as well not use that gasket.

Re-adjusting idle...
Good product if you're into tuning the idle but I guess that's not for me. As far as the PasswordJDM gasket, if the holes are there, then what's the f-ing point if it's special thermal material and spending $40? So basically the PasswordJDM gasket does NOTHING. My conclusion... STOCK it is for me! It's not even worth the trouble to risk a bad idle if I'm gaining 3 hp tops. Thanks for that helpful info!

 

No reason to disregard the product all together man. The idle might be fine after the install BUT, as previously mentioned the car will not warm up faster, however the idle control valve will take longer to get warmed up and your idle will be a little higher then normal until it reaches operating temperature.

 

If I remember right, on the h22 at least, the hoses that warm the IAC up come out of the thermo housing, not through the gasket.

The only hole in the h22 gasket is for the EGR.....just know that the coolant that flows to the IACV is solely so the motor doesn't freeze. Take the plate off that they flow into, they just flow through a closed chamber to warm it up. IMO not completely essential unless you live in antarctica.

 

It just seems that for the money (and even if money was no object), it's a bigger risk than it is reward. I'm building a bone stock side project (mostly for autocross but for semi-daily use as well)... a ported and polished milled B16 head on a gsr block with new OEM pistons and rods, and maybe a Blox intake manifold. Nothing that's gonna touch my H22A IMO. I thank you for the info because it stopped me from making a bad investment.

 

The point of the gasket is so the heat from the head does not heat soak the intake manifold, not to block off coolant flow.

It's $35....if you can't afford it, pick up a new hobby.

If I do get anything other than stock it will be the Hondata gasket. If the holes are there then nothing sets it apart from stock. As far as readjusting the idle, I'll have to look into it more to make a decision because that's just one more thing that COULD go wrong when it doesn't have to. I've already said it's not about the money, it's about risk vs reward.

 

IT DOESNT CHANGE THE IDLE, OMG!!!!!!!!!!!!!!!!!!!!!!!

expletive it, if you are too stupid to understand how this gasket works you don't even deserve to be living.

 

I don't deserve to be living according to you, but you're the idiot who thinks that the holes are there to make the car warm up faster. And you think that the material of the gasket actually makes one bit of difference when all of the holes in the gasket are the same as stock. Yeah, you sound like a real genius there buddy.

 

If you are getting worried over just that then I wouldn't even touch the car if I were you.

 

OMFG

The thick *** plastic is an insulator. What it does is it keeps the HEAT from the head from HEAT SOAKING the intake manifold. Materials make a huge ******* difference, if you don't think so go ask any college engineering professor.

AN-R told me that the hole is there to make the car warm up faster on a cold start, so sorry for believing someone who custom fabs headers for a living over your uneducated trailer park ***.

 

So, I'm looking at my Euro-R intake manifold and hondata gasket....the gasket doesn't block any holes. I assume its the same way on the USDM IM. My gasket looks nothing like the "hondata" gasket in the picture. It looks more like the password jdm one, but its an authentic hondata product. Maybe they updated their design?

THE HOLES ARE STILL THE SAME YOU PHUCKING MORON! You paid $35 for a GIMMICK. If the Hondata gasket blocks off the holes, then that ALONG with the thermal insulator makes the difference. But being Russian you're probably too stupid to think about that! You put the same holes as the stock gasket then it does NOTHING! If the Hondata gasket does what it says without any problems, then yes it's worth the money. Put holes in it, then they profit off of dumbasses like you! Do you really think you're gaining ANY power without the holes blocked off? If you do then you are the dumbest **** on Honda-Tech.

1. This isn't Moscow. You don't get a PhD in engineering just for graduating 8th grade.
2. So you're going by what people "tell you" in an advertisement. So basically you got a polyetheline reproduction of the gasket but with the stock holes in it.

Do you even understand what gaskets do? They are there to form a seal. Nothing else. So Hondata advertises that you gain 3 hp on the dyno, and that translates to you into buying a totally different material (polyethylene) that doesn't achieve the effect of the thermal plastic that Hondata uses which is used to BLOCK OFF THE HOLES (which is what makes it effective), on top of that, with the same hole pattern as the OEM, because they advertised it to you that way, and you think somehow it's better...

I rest my case.

Well it's nice to see SOMEBODY comment who actually bought a Hondata gasket who can provide some constructive feedback here!

So you're saying that your gasket from Hondata is not like the one pictured on their site (other than the obvious fact that they are showing a Type R in the pic)? That seems a little bit odd to me. Now I'm really beginning to wonder if they actually DID have some quality issues with the design. Unless of course, the design doesn't apply to the H-series manifold...

 

Damn, you're a fiesty one. I personally don't run the gasket, but the whole point of it is to thermally insulate the IM from the head, thereby reducing heat soak.

Now, I know you'll call BS on this, but here's another thing to think about. Why don't you find out the difference between the specific heats between water (or coolant, which shouldn't be that far off), and aluminum (I think that's what our IM's are made of).

Tell me, which one has a higher specific heat? Now, armed with that info, go ahead and rethink your position. Which would they want to isolate, the lukewarm coolant, or the bloody fsking hot head?

Not sure about this, but didn't hondata have their normal 'street' and 'race' manifold gasket???

could it be that the street has the coolant passage while the 'race' doesn't???


here are some good links I found looking into this issue

Because we are not doing the 'Race' install, you just cut out the hole on the side of the gasket so that coolant can flow through. Use an X-acto knife to carefully trim the piece out.</TD></TR></TABLE>


So the race version needs the hole blocked off....and the street version needs it cut out if you want coolant running through to the IM?

so that would mean, the race version = the street version

unless they have fixed that with pre-cut holes, I've contacted H-T sponsors and they asked me if I wanted to 'Street' or the 'Race' gasket

All the insulated IM gaskets keep the inatke manifold about 10degrees cooler which usually equal 2-3whp.
$35 is pretty cheap, and since the oem gasket costs about $18 your only really paying $17 more. Really not bad considering people pay an excess of $800 for a head package good for about 10 whp.

i advise you and anyone else in this thread to be more respectful or you can leave. one more remark like that and your gone...it won't be tollerated

 

My gasket doesn't specify wether its street or race. I bought it from an h-t sponsor. I can post pics of it over the manifold if you guys want to see.
