Looking around for heat exchangers, it looks like Billy Boat is about it here in the US. Mittlemotor lists two different diameters but lists no manufacturer. It looks like GHL doesn't do Porsche stuff anymore?
*edit* added Hayward & Scott
BB - $2310 pr
MM - E 1469 each That's $1847 at today's exchange rate - each!! You will get a 19.5% discount if shipped to the US, however.
H&S GBP 1400 pr - they look most like factory exchangers
What else is available now?
That brings up another idea. What are the odds of buying Bursch headers and fabbing HE's and ceramic coating the whole lot?
Mittlemotor HEs
Billy Boat HEs
Bursch Headers
Hayward & Scott
Look up Hayward and scott. Not cheap but looks nice. Many people have talked about fabbing up their own but it rarely happens.
put a big alternator and go electric...thats my latest, love it.

I've got no heat in my -6, and was trying hard not to think about the cost of heat exchangers - though I'm glad they're still available. I'd been eyeing the heated seat inserts at Camp914, but an electric heater with enough umph to clear the windshield would still be a good idea...
i have heard the bb and stainless versions.... are more for the thought ..than the heat....
Use these:

They bolt over the exhaust and turn a simple tube into a heat exchanger.

I have a set of B&Bs. Will let you know how they work once we finish the conversion.
I have a couple of sets of mangy /6s ... they can be fixed, but they ain't pretty.
$4K is a new high. Last ones I saw were $2.2K
Ron, the thing I've read about the BB is that the fit at the muffler (driver side?) is off a bit. I'd love to hear how they fit and function for you!
I do like the look of the Hayward & Scott.
what is the going price for original 914/6 heat exch that are in usable condition?
AA has some a left one that needs work for about $450 on ebay.
...self lubricating
afraid of extinction, he has gone into self preservation mode.

the pipe bends are groovy
What sucks about original heat exchangers is that they measure 1 3/8" and taper to about 1 1/4 on the inside. Not optimal for a bigger motor. My 3.2 runs fine on them, but I know I am probably losing a bit of HP with them. I should be running 1 5/8"
About 50% of the B&B's I've sold/bought had problems. I won't get them anymore, as it costs too much to round trip ship those things.
Heat exchangers of mild steel = future life insurance payout for your beneficiaries
Every set of factory 914-6 HE's I've ever seen have that same pitting as the spendy ones on eBay. And every set of 6 HE's that have come off a running car usually needs a little repair.
FWIW, the much storied carb'd 3.0 from Bruce Anderson's book, was a 914-6 with factory HE's. The factory HE's flow really well.
So, what are you using on builds now, Perry?
. The factory HE's flow really well.
I have the BB`s on my stock 2.0 with heat ...they suck for heat(low air flow) and they where a real bitch to attach! ...i put them on for the bigger I.D with Triad muffler that had to be custom fit by Dave ,,the flange on the BB is not square with the back of the car they are angled in to each other ...this complete system will most likely be for sale soon .. 90 % sure im go n back to stock
who has cheap six headers?
I haven't done any 6 conversions in a few years Sean, been wrapped up with other stuff.
Get a set of headers and make your own heater boxes.
Whatever you do, do NOT weld the boxes to the headers ...
Here are some "cheap" ones on Ebay! Yikes!!

it is too darn bad there is no one to tackle the job of building some hes that work, or a reproduction of orig...and do a decent job of it
what does a nos set of hes go for these days...iffin they can be had
Crack kills. Welding opens up the potential for cracks .
So does anyone know of a shop that would or does mandrel bend the pipes? A make your own option is cool, but i wouldnt want to do it from a box of U bends.
I called MSDS to see if i could buy just the bent pipe and build my own for the svx swap. I got the "never going to happen" story. told me to call jegs and get a box of U pipe.

I'm sure I'll get a for this, but John over at SSI apparently did all the work to put them into production but never did.
I wonder if a big enough group buy would get him there. It's a big if...
I'll be in the market soon, and frankly don't love any of the choices.

I've definitely got enough straight pipe in one header on either side for the 6.5", not sure about the 9". But the photo for the 6.5" shows the inlet and outlet ports are not in-plane the way they are for the 9" version shown in this thread. Have to get further under the car with a tape measure tomorrow...
Also, the site may be a little screwy, but it's giving me the same $126.95 price for either size/version.
The SSI's for the -4 are now available again.
Mittelmotor, Stoeckl and other German vendors have them
http://www.mittelmotor.de/content/news/activenews_view.asp?articleID=72
So I hope it is possible to get the SSI's for the -6 in the future.
