[Vwdiesel] Jet Hot coating

[mikitka]

 I have been toying around the idea of having my exhaust manifold, down pipe
and possibly intake manifold Extrude Honed and then Jet Hot coated.  Now the
one coating is good up to 1200 degrees. Does the exhaust manifold and down
pipe get hotter than that on a turboed 1.6?  Since I will be tearing back
into the engine in a few weeks, (still have not been able to finish the
garage) I was just wondering about these two ideas. I know it isn't a race
engine, but reducing engine compartment temps has got to help as well as
increasing air flow by extrude honeing. Since I lead a simple life with no
real hobbies, don't smoke, drink, just my family and a 65 Impala SS resto
project and the jetta. I figure I can work a little extra $$ into some
possible beneficial modifications since I plan on keeping the jetta a long
time. Just some ideas I have been thinking about.
Any suggestions/comment/ideas?
Here are the two links.
