Heat exchangers for a six, Who makes the best? Options

[Johny Blackstain]

I'm not 18 anymore & require heat in my car. I bought my six off the 914world classifieds 2 yrs ago & have found the car to be a blast, except in the winter. Very good for the air cooled engine, very bad for my bones. Obviously I have headers & I love the power, torque & sound I get out of them. I'd like to presume that the original heat exchangers were removed for the number 1 reason here on the East Coast... RUST & $COST$. I can live w/out A/C, but heat is a must. Suggestions? The six is sporting a high compression 2.7.

Johnny et al,
did you end up buying a set of exchangers from Hayward & Scott ?

I've been looking for a set of heat exchangers myself but haven't been too keen on the BB & GHL versions. Similar to yourself I liked the look of the Hayward & Scott version which seemed the most similar to the originals but in stainless. They also look like they should flow OK. After some searching I've found a couple of people who have them in the UK and the reports of fit, quality and heat generated are good.

I see on here it has been commented about the preformed bends that are welded together to make the shape (you can see the construction technique in the plain 911 header set also produced by Hayward & Scott in the picture below). Some strong comments on here about this being dangerous. I would agree with this for carbon steel manifold tubes but with the thick gauge stainless used in the Hayward & Scott items it won't rust anyway. Not a problem as long as they are welded properly to start with, which is easy to check. The gauge of stainless tube that they use means that they can't form the tighter bends so they use preformed bends and weld then together on a jig. This is a time consuming way to make them but they say they would rather do this than use thinner gauge tube.
I've added a couple of pictures below that I got from a guy who bought a set 8 years ago. The area of enclosed header pipe in the heat exchanger boxes looks only slightly less then the originals. And another comment I have had from someone who has a set is that the heat generated is equal to his originals that he replaced. The picture of the set bolted up to the engine helps to show just how big the boxes are.

The costs of the Hayward & Scott items was the main problem for me when I was been able to find BB or GHL versions in the US for less than $1900 when I looked 12 months ago. Now that the £/$ exchange rate has moved to where it is, then this is looking less appealing anyway. And presumably £1300 for the Hayward & Scott items is looking more appealing to your guys in the US. My loss is your gain !

Ian is prepared to offer some more discount for multiple sets. He offered me £1170+vat for 3 sets or £1105+vat for 5 sets if we could rustle up the custom. I hoped he would go further but I haven't given up yet.

I am interested in one set but need the price to be lower then the std website listed price of £1300+vat to justify it. It's a lot of money to pay for a few winter outings given you guys are kind enough to send a load of Gulf Stream water to keep us warm each winter ! Many thanks !

Ian said to me the other day that someone from the US had ordered a set and someone else was thinking about it. Anyone on here ?
Anyone fancy combining forces to get the best deal for all ?
I'm sure Ian would accept orders separately to keep things simple if we could just get a group together.
(Ian can do them in different diameters as required)

Yes, I decided to go w/ the Hayward & Scott's & got a price of £1305.00 shipped. I ordered them w/ 1 5/8" tube diameter & 2.5" collector diameter. Now I'm just waiting on my order; should be 2 more weeks. Cost is high but I have no intention of ever selling the car & just want to enjoy it as much as possible.
