A great place to get things coated to reduce heat/friction/etc. is Swain Tech. Do a search on the internet for the site.

I thermal coated mine with over-the-counter aerosol sprays. But it's really not much use if you don't have a spacer between the head and intake manifold. You might want to coat the upper intake manifold and leave the bottom manifold alone so it can dissipate heat.

Not a coating, but there is the Outlaw Engineering Thermoblock spacer kit for only $115.00
http://www.outlawengineering.com/nissansr20hiframe.html
Supposedly good for 9HP and 7Lbs of torque...
I give it two thumbs up!

If i put a hand on my intake manifold (w/ the outlaw thermo gaskets), its cool to the touch, doesn't even feel warm even after tearing around all day.

Do the same thing in my friend's honda with the hondata thermo gasket, and the manifold still gets blazing hot.

does the IM get that hot that more than the spacer is needed? Other than putting more air over it, I don't know another way to cool it. I'd be worried or want to see some tests/data that show that a coating isn't trapping heat in.

The IM is cool to the touch, right next to the head, where it would be the hottest. I'm sold on the product. The kit comes w/ three spacers. One that goes between the IM and the head. One that goes between the upper section of the IM and the lower half. And one that goes between the IM and throttle Body. It also includes fittings to re-route the coolant line that goes thru your throttle body. The kit includes detailed installation instructions, and all the new hardware that is required. It is very complete.

So you say this kit from Outlaw works???
Cool, if it does. Ever since I rode my car around for a couple of hours without a hood my intake manifold was cool to the touch and would like to have that advantage without taking my hood off.

this is for the 91 se-r correct? The have an application for the highport sr20de/t.

for 115 bucks id like to see some proof.
Check out outlaw's website they have temp. data from before and after. Or even better give them a call... I talked to one of the doods from there for ~45mins, very nice and informed guy.

Even if your personal results are 1/2 what the company claims, that is still a great hp/$ ratio.
Adding thermal blocking spacers and blocking off water to the intake manifold and throttle body are 2 classic ways of building hp. I really don't think you can go wrong for the price.
Steve, are you experiencing any cold start driveability issues or greater than usual combustion deposits inside the manifold since you have added your kit?

They have dyno numbers along with many testimonials that their product does exactly as they say it does. It was spoken about for months as they developed the SR20 kit for us. Search!

If you have a spacer between the head and intake manifold and that you bypassed the coolant lines, the coating for sure will not be trapping heat in as it is much hotter in the engine compartment then below the manifold surface. The heat convection due to the cold air charge within will maintain the manifold metal at a cold temperature. The radiating heat from the engine and the heat conduction due to the heated, under-hood air will be a constant heat source for the intake manifold.

Sr20falcon, if you are going to get a spacer, then you can coat both the upper and lower manifold. If you are not, you should only coat the upper manifold, and you must bypass the coolant lines.

What I use to coat, was white epoxy paint, white poly-urethane paint, and and acrylic clear coat for outer layer. Epoxy, poly-urethane and acrylic all have very low heat conductivity and the color white is the most reflective against heat radiation. These paints however will melt under high temperatures. Never use black or metal(gold, silver) color paints. Black acts as a black-body radiator and will absorb radiation quicker than anything, but would be a good choice for painting radiator or intercooler though. Metal color paints contains many metal flakes and particles to give it that color hence these paints will have very high heat conductivity. Also don't get the high temperature engine paints eventhough they are silicone/ceramic based. The properties of these paint is high heat permeability which enables heat to transfer pass them with little hindrance, hence they can withstand extreme temperatures. If you want to get professional level coatings, you can check out www.techlinecoatings.com. Hope your question is answered.

I don't believe Outlaw makes a kit for this car

But it might be worth a shot :tongue:

The 6 cylinder on Matt's car has both intake and header on top of each other
on the same side of the engine. Of course the header is under the intake manifold so the manifold gets to soak all of the heat from the header.
Thanks for the idea of Swain Coatings, that is a good idea and I heard the coating really does do the job they claim.

I had it backward then...I was thinking in terms of a coating that would dissipate heat quicker instead of not conduct it in the first place. I was looking at heat by conduction from the head as inevitable. There are coatings that help dissipate heat quicker. I believe Swain makes it actually. Sorry for the confusion

Yeah I Should Of Explained Better.what I Want Is A Spray On Coating For The Bottom Of My Intake,being The Header Is Right Under It.i Will Check Into The Spacer For My Sentra Though.if Anyone Can Help Thanks A Lot.i Have A Falcon Body But Its The Only Thing Falcon On The Car Its Pretty Much A Winston Cup Or A Nextel Cup Car With A 67 Style Body I Just Call It The Falcon
