I desire to thermal coat the underside of my heat shield but I think that "Thor" himself has tightened the bolts to the exhaust manifold. Bolt sieze maybe???

BUt here's my question: Are there not 2 heat shield's? One on top of the exhaust manifold and the other separating the turbo from the radiator.

Has anyone been successful in taking their heatshield off? I gave her all she had this morning but my tools gave me the big "hell no!"


And, would you guys also reflective coat the top side of the exhaust manifold heatshield (to promote more efficient heat dissipation out of the hood opening)?

Thanks in advance

Manifold heat sheild is easy to take off, if the bolts will cooperate with you it is. The lower heat sheild is a b!tch to get off. I took the turbo outof the car to get the heat sheild off. I also replaced the O2 housing so taking the turbo out was a must anyways.

 

I'm killing myself trying to make the upper bolts give. I really don't want to have to take the turbo out to get to the turbo heatshield. How bout just removing the radiator? No, that's BAD I'd have to drain/bleed/burp/refill it then...

YOu know any tiny handed people

 

Yeah, I took mine off and painted them black again (they looked almost rusty from the factory). The bolts are tight, but you can do it. Put the 10mm socket on there and hit the ratchet (or wrench) with the palm of your hand. Don't try to pry it loose, use a smack or two and they break right loose. If you have an air ratchet of impact gun with small enough sockets that helps; but not at all necessary. I have them and didn't even use them, just a socket and ratchet. If you do use air to remove them, do NOT use air to put them back on. Just use your hands.

Good luck, and eat your wheaties!

 

Man, love that look with no wing!! Looks sweet!!

 

the car looks "formal " without the wing

 

Thanks. The cops and boy racerz were paying too much attention to me with the wing on. Plus now it's a sleeper. Best is when I take out guys on their Harleys

Back to the bolt thing; even after a bran muffin, I can't budge them. How many miles into your car did you do take your's off? I'm at 20K and my car is not garaged.

Along the topic of heatshielding, anybody come up with anything that will sheild the cold air intake from the rest of the engine bay?

 

Be carefull with the manifold heat sheild bolts. I busted/twisted the head off of one and I have taken mine off several times. The damn thing just seized. No matter what I did. I finally said screw it and torqued down hard on it and 'snap'. If you have never taken this thing off since you had yer car then it's gonna be a tight sucker. Their may be a possibilty that you won't get it off without snaping it.

 

Mine had about 6K on the clock when I took it off. Like I said, I couldn't pry it loose to save my life, but a few good whacks with the heal of my hand (or a small hammer or such) on the wrench and POP they came loose.

Extend the leverage, use physics. The longer the handle on the wrench the more leverage. Then give it a smack. Good luck!

 

As far as blocking warm air from the intake, there are aftermarket sheilds you can buy. None are cheap though. I'm sure you could fashion something out of metal with little effort. I'm sure I'll get all kinds of reponses for this statement, but I don't think it makes much difference. I don't want to get into a rant about that though. What I did do was leave the factory snorkle in place so when I'm moving it gets blown with cooler air.

 

I went with the wingless look for a bit.

 

Yeah I left the snorkle on aswell... I think that I may do a cardboard diagram of the area I want to shield and go to the HOme DESpot (Depot) and fabricate something. Every little bit helps when you are trying to keep the air charge "cool" - I know the FMIC is the determinig factor in the temp of the charge but it will work more efficiently if it encounters a cooler intake charge rather than a warm (outside air and ambient engine temp) charge.

Last, anyone heat wrap their upper IC pipe - goal being to prevent it from getting as hot as it would from underhood temps, thus maximizing the efficiency of the "cold air" intake concept? I know sleves are about $20 buck and good for 1800 degrees...

 

stvbreal, car looks good like that. What springs/coil overs did you use to lower it?

I don't think heat wrapping the IC piping will do much good; it doesn't get that hot. I was actually thinking the exact same thing as you for keeping the intake cool. Cut out a cardboard template and make it fit, then use that to cut some aluminum sheeting (or some such). Like I said, I doubt it would be that difficult. If you do something like that post it up; we'd all love to save the R&D time. Thanks!

 

Tein S-Techs lowered it pretty good but the rear could go a tad lower.

 

Even if you get the lower shield bolts off, it will not come out of the car unless you remove the radiator. I just had my heat shields ceramic coated. Check it out here: http://users2.ev1.net/~subaru/evo_web/evo_exhaust.htm
