Just bought this, it is indeed epic stuff:


If link doesn't work, search for this:

X-Treme Tape TPE-X36ZLB Silicone Rubber Self Fusing Tape, 1" x 36', Triangular, Black

It's also great for wiring harness that see high heat, like ignition and injector harnesses.

+1. That stuff is bitchin' I use it on wiring harnesses and also for securing fire sleeve (much like Jeff has already done)

+1, just bought 2 more rolls to rewrap my cop harness.

I'm a firm believer that every turbo'd miata owner should invest in the silicone mishimoto heater hoses. The fluro-silicone is good up to 500deg and it won't thermal cycle harden.

They also look purty, which I know at least Jeff cares about ...

My only suggestion would be to oversize the holes some to let the cooler and radiator grow without fatiguing each other. If you can find some rubber grommets, that would be even better.

Good advice. I didn't think about that. Will the oil cooler/aluminum really expand that much? Or is it mostly vibration dampening.

Also is there a simple trick to fitting the frayed ends of the stainless lines into the connector sleeves without buying the special tool?

e-tape the end.

I bought these as well, for the exact same reason. Gives me one less thing to worry about. For the NB readers in the audience, Mishimoto does not list fitment for the NB but the NA 1.8 ones fit with no problem.

This stuff is awesome. I'm about to go buy a case of it.

Jeff that oil cooler is very clean!

I would think the rubber gromets would help. Your logic for them seems sound.

SantaMonk is here, still hungover from the holidays!
Who wants a roll of this ultraballersuperjdmyo tape? Electrical Tape | MSCDirect.com
I use it at work for sealing slightly pressurized containers of bovine serum, but it's "too sticky" (to itself) for some of my coworkers. I have three rolls.

Me!!! :)

Ho Ho Ho, one down. Pm your address.

Comments:

1. I've never had those motor mount bolts come loose if torqued to spec. That said, blue Loktite never hurts.

2. AN hose assembly instructions: http://www.jegs.com/instructions/555...ngAssembly.pdf

3. Firesleeve has a specific purpose. It is NOT meant to be a thermal barrier for radiative heat. It is a good barrier for conductive heat, and it also chars when exposed to an open flame to protect the hose (buy time) in a fire. It comes from aerospace, and it's use is mandatory on aircraft for any flexible line that carries combustible fluids such as fuel, oil, hydraulics, etc.

4. Lines exposed to metal that is so hot that it glows (radiates) need a reflective covering to handle the radiation (in aerospace, this is handled by using stainless steel braided lines that naturally reflect). Firesleeve is not a reflective covering, and the color of firesleeve that you've chosen (black) is the worst possible color. Note that you don't have to use that shitty tape stuff for your heater hose, they make reflective sleeving: Thermo-Tec Thermo-Sleeve Insulation - Free Shipping on All Orders @ JEGS.

5. The other thing I've noticed is that our heater hoses are probably OK without anything at all, they seem to be sufficiently cooled by the coolant flowing through them. For example, if you're using a simple rubber or silicone turbo oil drain hose, it's not uncommon for them to cook away and need replacement any time they are disassembled. In contrast, the heater hose connection at the OEM metal engine-side tube under the manifold always disassembles easily. So . . . .

6. Stainless-braided lines make excellent metal saws. Be careful to secure them whenever they run close to, well, anything. Nylon-braided hoses are a nice alternative to reduce this effect and are also lighter weight (i.e., http://www.jegs.com/p/JEGS-Performan...rPage=60&pno=1). One of the advantages of your oil cooler location is that you are not exposing the cooler or the lines to road debris. So SS is serious overkill.

BTW, love the tabs on the radiator. That's quality stuff right there.

Edit: oops

:party:

I see so many on this board wrap their heater core hoses with all sorts of things when as you've stated, they need to spend less time trying to insulate their hoses and more time trying reflect heat away. I think most would be better off buying new lines (either OEM or fluro-silicone) and either sheathing them in a reflective sleeve or building a reflective sheet metal heat shield which fits between the hoses and master cylinder with maybe some additional reflective insulation to keep the shield from absorbing and radiating heat itself.

Blaen99 welded AN fittings to an aluminum NB heater core, and has SS throughout, it's very nice. Just remember they don't flex as well. One goes to the turbo, another has a 90* fitting on the end iirc.

He's using FM heatshield so heat/firesleeve on heater hoses is pointless.

I can't really say for sure, but a lot of the nice oil cooler kits I see use rubber isolators on them. For mine I just over sized the holes and use a nylon lock nut with a thru bolt and just snug everything down. That why if it needs to move a little, its not putting stress on the heat exchanger.
