i did the throttle body coolant bypass already to reduce intake temps a little, since i already did that would the Honda gasket do anything further being i think it pretty much does the same thing?

 

Honestly, it doesn't do shit. Well, you won't notice anything from it if that is what you are expecting.

 

well what im asking is, will it lower my intake temps any more, being i already did the throttle body collant bypass?

 

Well, what he's saying is, do not waste any time on shit that does nothing but make you feel better psychologically.

 

actually the hondata works....and it works well. do either of you guys have it installed?

however, it is such a PITA job that it's not really worth doing unless you have another reason to take off the IM.

for me, i needed to port match my IM to my new spoon tb, so it was coming off anyways. perfect time to put the img on.

not something i would do without another reason to remove the img though.

 

so you also did another mod included with the img , so your not to sure what one is actually giving you the benifit when in reality its probably the intake manifold work you did, just a guess

 

it a very good product, as far as i am told. There is a write up on the in the s2000.org section, it lower the intake SIGNIFICANTLY (20-30 i think), read that article and you will see, i think it is one of the very few mod that actually IMPROVE the S with little drawback. i am no mechanic expert, but i spoke to one with a vast knowledge with Honda/Acura, Hondata Head Gasket has worked very well on Honda engine (civic, RSX and S2000). there are only two possible draw back that i can think of:

1.the gasket block off the coolant feed to the intake manifold (you gain some power this way), that coolant line is meant to heat up the intake manifold from freezing, so unless you are in a extremely cold area, you should not have any problem

2. installing this gasket will require taking the head off, i will be a 4-5 hours job, so be prepare to pay a big labor cost (the gasket itself is about $60 i think)

as you all know, s2000 has very few areas for improvement, and i think this will actually improve it. the hotter the weather, the more benefit you will get from it. i have jsut moved from Boston (cooold) to Texas (hooot). so this will be my next mod that i will do

i am well aware what did what. and haoheomap pretty much nailed it: the hotter the weather, the better the benefit.

that, coupled with the fact that i can rest my hand very comfortably on the IM after some hard driving or just some sitting in the city driving.

the img doesn't add anything; it reduces the amount of power lost from heat soak.

i can pretty much guarantee that if the weather is warm and you had two stock s2000s next to each other, and the only variable being one has the hondata img, the one with the img would get the better jump.

take it for what it's worth. like i said, and many others too, it's not something to do just by itself. but it's a great idea to do if you have another reason to take the IM off. heat soak sucks...this is just another way to combat that, especially in the summer or the track.

 

when the head is off, there are one more thing you could replace if you are approaching 70-80k: the thermostat, in our car, it started to fail at this kind of millage( though there are others that is fine for a long time), when the thermostat fail, you will have to disconnect a whole bunch of hoses and part to get there, and the working angle is still not easy, when the head is off, it is extremely easy to get to the thermostat, this will save you some trouble on the long run.

to my opinion, a mod worth doing is not necessarily a mod that gain power, when i made a commitment go buying the s2000, i have never looking into making the car faster on the straight away alone, heck i didnt even have an intake on the car (and that is for a good reason, if you wonder why, keep searching), to me this Hondata gasket is well worth the effort, cuz it make the car BETTER.(fun factor is the main reason i have the S, not fast factor).

 

Installing the IMG DOES NOT require removal of the head.

It requires removal of the intake manifold.

I bought one years ago but only installed when I replaced my engine a year ago.

I have since had reason to remove the intake manifold by itself. I can attest that it is a pain in the arse to do. I did it by removing all the bolts/nuts (the hard part) and pulling it away from the engine but not completely removing it. I believe this is the method Todd Marcucci recommends in his write up.

What the IMG does is insulate the intake manifold from the head. As a result the intake charge is passing through much less hot metal on it's way into the engine. A worthwhile mod in my opinion.
