Or if you want a quicker turn around grab a spare manifold. Have it machined and ceramic coated and then you can just swap them over.

I agree that the price is reasonable.

Proper, decent ceramic coating is expensive. John Lynch of Jet Hot < www.jet-hot.com.au - Hi Performance Coating > quoted me $325.00 + GST for the full clean and coating service, late last year. He's done plenty of TD5 manifolds before. That is what I would expect to pay for a proper job of it.

Yep, my $100 job started flaking off. I guess you get what you pay for. But I believe that it's worth it, as it lowers underbonnet temperatures considerably.

I've just ordered an exchange machined and ceramic coated manifold from APT. Cost was $550 plus freight. Hopefully I should get it next week, so I'll post up some pics. I also ordered a set of wurth studs and nuts from that ebay guy in the UK.

However, I just noticed some guy is selling a brand new manifold for $125

I would have gotten that had I seen it before. So could be an option for you, buy that and get it coated. Assuming he will post it.

Jet Hot did the work for me all those years ago..
Still going strong

I think those manifolds are the Chinese knock off ones. Caveat Emptor...

oh, I didn't realise there were chinese knock offs. available Does make sense, as I was wondering why he had 2.

Lucky I went with APT first up then

So $775 all up
Does the ceramic coating improve performance ?
Good point on the underbonnet Temperature
I reckon I kept cooking the second battery in my old
D2 because of the exhaust being next to it
I even had a special twin skin heat shield made up

Land864. Yes the turbo gets it a bit warm, was sensible to fit a shield.

If you're not using the battery often that helps cook them as well
