I am thinking about having my Heat Exchangers and Mufflers Jet Hot coated.
Has anyone done this on their Type IV 2.0L? My concern is how does this affect the heat at the heads compared to standard? Will it increase the temps or will they be about the same? Thanks in advance, Scott |

I am not sure how well this would work with stock heat exchangers though as they need to prep and coat the inside and outside of the pipes and with the heat exchangers your pipes are wrapped in the ductwork for your heating system. Even if you did get them coated, your heater would most likely be affected as the point of jet-hot is to keep heat from penertating the pipes, less heat escaping the pipes means less heat in the cabin. If you are just looking to increase durability then find a set of SS heat exchangers as the cost is not much more anyways. The cost to coat my system was over $300 and did turn out to be higher then the original estimate. |

That's what I needed to know! Will look into SS.

I'd recommend the Jet-Hot process.
I also prefer the stock h/e's over the aftermarket ones. The stainless ones last longer, but the exhaust flanges are half the thickness and are more problematic than stock ones, as far as getting exhaust leaks. If I had a real pristine set of stock h/e's I'd go the Jet-hot route. |

I rode by Jet Hot here in NC last week. I have seen a set of custom Big Block Ford truck headers done. After two years of use and car shows they still look great.

Had a set of Hedman shorty headers JH coated for a bb 427 straight out of the box. Rust ate its way through within 18 months- though this was in Mobile AL so I can't say for certain that the salt air didn't have an effect.

That's what I needed to know! Will look into SS. (IMG:style_emoticons/default/agree.gif) ... for a driver - SS HE's are the best way to go, & you can replace the mild steel flanges at the muffler if they're corroded to too thin (as noted above), with new SS Flanges from Engman (a member vendor/banner on here), if you want to cut the old off & reweld the new on (or have it done), then those will outlast you & maybe the 914! There are several sets FS now/recently in the classifieds on here, 914club, clubNARP, Pelican, TheSambe & eBay, etc. - expect to pay +/- $400-500 for a nice set of used 2.0 SS HE's from what I'm seeing lately. and ............

I Jet Hot coated a set of Kerry Hunter Headers. The car later went up in flames, The Headers were the only thing left and they were perfect. I found a local guy that Ceramic coats headers, but Jet-Hot is better quality

Thanks to all the responses!
I have talked to a local Jet Hot supplier and he is going to do this for a fair price. $100 each including the blasting. I will get photos before and after then post them here. |

I have Bursch 914-6 headers that were Jet Hot coated around 6 years ago and have held up beautifully. Turnaround and pricing were very acceptable too.

I've heard mixed reviews... But I actually have something to back it up with..
My dad's corvette sidepipes were jet-hot coated. This car was never put away wet, and we live in Sunny southern california. It is driven almost every weekend. Despite this however, rust is starting to eat it's way through the ceramic, which is not at all appealing to the eyes. Now, the ceramic coating itself has saved my legs from some really bad burns, but it is not as durable as we both wuld have liked. |

Obviously nothing can totally prevent mild steel from oxidizing except (possibly) preventing all contact with oxidizers. I thought normally Jet Hot coated the inside as well as the outside so that no air or water should contact the bare metal??? |

IIRC there's a limit to how long they can reach inside tubing.

I have sent off both of my HX to the coaters. I am going to compare head temps and engine bay temps both before and after.
Overall it should provide better even heating throughout the HX's which will offer before flow. It should also provide better heating in the cab which I really do not need most of the year. Update soon! |

I had them redo my 914-6 heat exchangers. They patched a few thin spots they found and coated them in a timely manner for a reasonable price. Their work seems to be holding up fine.

I've found that not all ceramic coatings are created equal.
cip1.com mufflers don't last worth a crap and I've seen independent shops coating that were fantastic. Manicuring makes a huge difference, if all the sharp edges, splatter and welds are carefully ground round and/or smooth it does a much nicer job. Sharp/square edges get a very thin coating, just like paint and that's where the rust starts. |

How do you figure it would provide better heating inside the cab? If they coat the pipes properly inside and out down the length of the pipe (including under the air ducting) then the jethot is going to reduce the heat transfer from the exhaust air to the cabin air.
The only way i could see this not affacting the heat is if they just coated the outside of the entire heat exchanger and not the pipes under the ducting which does not make much sense to me as you are not getting any rust protection on the pipes themselves. Let us know how it turns out. I have sent off both of my HX to the coaters. I am going to compare head temps and engine bay temps both before and after. Overall it should provide better even heating throughout the HX's which will offer before flow. It should also provide better heating in the cab which I really do not need most of the year.
