Have you noticed any difference in the temperature of the UIM when you touch it? I had a phenolic resin intake manifold insulator fitted to my old G60 turbo and it made a hell of a difference to the temp of the manifold.

 

Lots of honda guys run these and have found that they do work and seal better than stock. I would use them if I had them sitting around.

 

Sweet, its time for me to change the oem lim gaskets and I have my ebay gaskets I bought months ago...

 

^I don't know man...this guys car exploded.

 

Because of intake gaskets??!!??

 

id like to add about 6 months ago i bought these gaskets off ebay, and they have worked great. im uisng the lim and uim gaskets and iv removed both amnifodl about 4 time and re-used the sanme gaskets and still no leaks or anything. they are kinda strange cause when you remove them after using them they look melted but they just mold to any imperfections with the heat and seal great .

 

I did not get mine on Ebay but I believe the ones that I have were made by the same PPP company. I've had them on for 3+ years now and have removed the UIM a few times and reused the gasket. In my opinion the are definitely better that the stock metal ones, which once compresed, remain compressed and may or may not reseal.

As far has temperature, they have phenolic properties and remain cooler for the first hour or so, good for drag racing I guess. Eventually after an hour of stomping on the gas, the UIM reached the same temprature as with the stock metal gasket. I assumed via the bolts etc. I used a non-contact temperature gun to measure surface heat. it was a while ago and I can't remember what the temps were. I eventually ceramic coated the insides of the manifolds and intercooler piping along with several other mods to try and bring down charge air temps. It worked if I remember correctly charge air temps of 142 max, 135 norm, lowered coolant temps too, 202 max. (I live in California, so I have to try and keep my mods visually stock-looking, meaning smallish M2 SMIC, top painted black, Mazda logo on top of M2 CF intake ...LOL ...If you have ever been clocked at 163, tossed in jail and cited for every illegal mod on your car...then you'll know where I coming from.)

Anyways...overall I think the gasket are worth the money, especially if your doing the gradual mod build up and have to remove the UIM more than once.

 

honda/subaru/mitsu guys have been using gaskets like these for years, not suprised to hear that they've done well for those on here that own them too

 

i have these for sale for $30 bucks shipped! brand new I've used them before on my other fd's and i honestly really like them.

 

the stock ones aren't paper they are metal whats the point in saving a few dollars on gaskets any way and experiment with new materials when the stock work great?

 

The original stock LIM gasket is paper on the 93s.

The idea is to reduce heat conduction from the block to the intake, and thus keep intake temps down. Based on how hot the intake gets during normal operation, it's far from a hokey concept.

Yep. I spent the better part of an hour trying to scrape all the old gasket off without damaging the surface. Does Mazda still carry the paper gaskets for 93s or did they switch over to metal?

 

They are metal now.

 

Yes. All metal. Ordered one a while back from MALLOY. Can't remember the price right now, wasn't bad though.....$8-$10 ?

 

I have just purchased this as well~~~~ I will also let you guys know how it goes~~~ cheers.

 

i have a set of those for my 20b... i i needed something reusable and didnt want to deal with trying to track down the stock gaskets (and i definitely didnt want to cut one from paper gasket material. its not installed yet. the ports/bolt holes match up pretty well. its relatively thick so its gonna add an extra mm or 2 to the height of the manifold, but i dont think it will matter much. hopefully it will hold up under the heat. -heath

 

hey are you guys using these gaskets dry or with some gasket sealant?

 

Heath, I would use them dry....there is no need for gasket maker IMO. Where did you get the 20B ones?

 

ebay http://cgi.ebay.com/ebaymotors/Rx7-R...spagenameZWDVW
(i have no affiliation with this seller, and cant vouch for the how the gaskets work... i can just say that all of the holes from the stock 20b gasket are there, and line up rather well)

 

i'm using mine dry... i take my UIM off all of the time and its great not having to worry about new gaskets. i definetly recommend them but you may have to do a little trimming around the port holes

 

bringing this back from the dead, autospeed just ran a good article on the use of these insulated gaskets.

Summary

* The intake ran 30 degrees F (17 degrees C) cooler at cruise and at least 50 degrees F (28 degrees C) cooler at idle;
* According to my dyno plots, I gained up to 7 horsepower and 11 ft-lbs of torque over the major portion of the power curve.
* My best time at the track was ~0.1 seconds quicker and ~1 mph faster.

I know this is a few days late, but results will vary from car to car.... I can almost promise you will not see that big of a difference on our cars.

 

So... OEM or eBay gaskets ???

 

from the dead....so is it worth getting?

 

No
