No idea! could you just heatwrap it? i guess it wouldnt be as efficient but it's a lot cheaper.
 
Kelv, unfortunately that wont work. As you may know, heat wrap is designed to keep the heat within the exhaust piping and reduce under bonnet temps.

Mild steel basically wont cope' when really hot' and the pipework is only 1.5mm thick, so it will just crack and fall apart.
anyway, heres some new pics:

Sadly, Mild steel basically peels/falls apart in small chunks inside the pipe when it gets 'really hot' and these follow the the direction of the exhaust gas into the turbocharger and it could potentially ruin the turbo.

Oh yeah, when i got my stainless steel manifold made up i asked him about heatwrap and he said 'well put it this way, if you heatwrap it your five year warrenty will be voided' so i assumed it was a stainless only thing. Ceramic coating would be the best bet then i reckon, he did mention getting that done so perhaps if you ring a custom exhaust place nearer yourself they might know someone who does ceramic work

Depending on the cost of that piping, it could quite easily tarnish and corrode abit, so some sort of coating would be best.
I got some exhaust stuff from here: http://stores.ebay.co.uk/RPM-Motorsport
Should be some suitable wrap on there

thanks for the link, i'll have a look n see what they have. Did you use heat wrap or was it a coating?

Yea I think the red head was pretty cool.

Yeah i liked the red the most. I ve got a bit of a problem though because ive purchased blue pipe joiners for the intercooler piping. I dont think the blue/red combo will match. Most likely going to be a blue rocker now..
Besides, the white car- with red bits (ie the seats etc), is a Honda type R thing anyway :) .
 
I used heat wrap on my hotshot manifold. Havent had any problems, but Im likely gonna take it off as the manifold gasket is leaking and its hard to join the sections with the heatwrap on. It made a huge difference to the temp around the manifold though, and after a good thrash you can see the manifold glowing bright red if you look through the gaps in the wrap.
 
Thanks sri alan. Im going to get a ceramic coating done (inside and outside the pipe). Exhaust wrap isnt going to be suitable for this application. Any advice or recommendations are appreciated though. As kelv said i'm best to just try a few exhaust places by me and see if they do or know anyone.
 
I had a complete custom made system from ashley racing on my previous car.was expensive but top quality!
 
avoid using heat wrap. it's known to actually trap moisture in it, making short work of your steel manifold. only other suggestion I can make is some sort of heat shielding, but if space is at a premium there's not a lot you can do here.
 
Can you explain how heatwrap traps moisture in a manifold? Unless you physically pour water onto it when its cold and leave it over night? To apply heatwrap you have to get it slightly wet first. The first 30mins of use afterwards, the water evapourates. Have you ever seen a heatwrapped manifold after its been used? The steel or stainless glows red. Theres no way moisture would be trapped under it. you cant wrap cast manifolds as they crack. Stainless steel will be ok
 
I've never used the stuff. I've always been told not to for that reason, and I've been shown the pictures to go with it. Stainless should be ok, but still it's not recommended.
 
re Exhaust Coating

Could you not get it nickel, tin or chrome plated? Something like that, i could see it being a lot cheaper than any ceramic work.
That would give a similair level of coorsoion resistance that a stainless exhaust would.

Awesome project you'v got going out of curiosity how much is the manifold costing you?

Cheers. so far, looking at around £180 -£200. Should be £180 if all goes smoothly..I have designed the manifold myself so it has reduced the price quite a lot.

thanks mate, i'll look into it. Im awaiting a quote from a place called 'camcoat' for a suitable coating. Ive asked to see what coating they recommend. Hopefully it shouldnt cost more than £100 to get it coated inside and out.. Ive found a few cheap high temp paint coatings, but these are only good for upto 650 degrees celsius which isnt enough.

thats not too bad really or i dont think so, will they be keeping the design as that will also fit the 1.6 as well if i remember rightly? I take it, its designed for a specific turbo?

Are you sure? I don't think exhausts go much above 400 degrees C? I might lob some thermocouples on mine one night after work and check this out.

the original rough qoute i was given was £425 for him to design, fabricate and fit it.Then when i met up with him he went on to say that if i designed it, it would be cheaper and cheaper still if i fitted it myself.

There is nice one in america for the qg18de but it costs £400 and 6weeks fabrication time.

Yeah its specific to my turbo, but only the turbo flange being used on the manifold is specific for my turbo. the flange could be changed for a different turbo application. Yes it would fit a GA16.

It guess it depends on the material of the manifold. Ive heard Exhaust gas temps can reach upto 1200 degrees c. How much of this heat is soaked up into the manifold is going to be dependant on the material and pipe diameter.

The optimum gas temp is around 850 deggrees c apparently, above this temp means you have a lean fuel mixture. Lower than 800 means the mixture is too rich. ;)
