remove or not to remove...

[turboloon]

was wondering if i should remove the heat sheild from the exhaust manifold,whats the genral consensious on this...:?

 

[Smo]

Go for it.

 

[red reading]

why not paint it and put it back on?

 

[5GTIR]

I have to say, I think Nissan probably put it there for a good reason. Removing it all together will only increase your underbonnet temperatures which will inevitably reduce power. I think painting it and putting it back on could look good though.

 

[Trondelond]

Mine is off only because it's broken. I'd like to have it back. Keep it!

It's not like it's going to affect the intercooler pipe as that's on the hot side anyway and it'll cool the charge air once it passes through the core of the intercooler. I kept mine on though, it looked shitty and rusty so I sand blasted it and painted it in some black high temp paint just to smarten it up a bit.

Take it off, lag the manifold, elbow and downpipe with a good quality exhaust wrap that'll handle 1000 degrees C, clean the heatshield up, paint it with silver exhaust paint and put it back on with new fixings ! ;-)

thats assuming he can get if off, the bolts holding it on have a nasty habit of shearing off and leaving half the thread in the manifold :doh:

I agree though, take the bloody thing off and lag the IC pipes

 

[Animaldaz]

You could always polish it and paint it in clear hi-temp paint, thats what i did

how do you get the half threads ot of the manifold?

 

[Jonesy]

Take the bolts out after you have been for a run in the car should be a little easier to remove, just try not to burn yourself.

 

[stevepudney]

I had no intention of putting mine back on and I was going to be internally ported/polishing the manifold, so whilst I had the carbide grinder out I removed the heat shield mounts/turrets (with sheared off bolt threads) so the manifold was smooth, I also ground out all the webs between the runners so I could heatwrap it properly.

:shock: I'd like to see you do that ! :lol:
It would be even more difficult to remove as you wouldn't be able to go anywhere near the manifold !

If you're serious, you're better off using localised heat, from a blow torch or oxy/acetalyn torch.

just grind the bloody things off and put the useless heatshield in the bin

Pair of gloves and youl be fine, pussy :lol:

 

[davey red.r]

or you could ask that bloke off the fantastic 4, him that bursts into flames, to remove the bolts, dont think he would need gloves:lol: :lol:

 

[dannogti-r]

rip it off there!

 

[snoon]

i agree with steve, bin it, mine is long gone!!

 

[turboloon]

only reason i'm asking is cause i have the hybrid fmic and it's hard up against the heat sheild !!!

I'd 2nd that i'm thinking about making up a ali plate one couple of mm think doesn't need to be much Who knows either that or just heat wrap it like it's said Above
