Hello all,
Forgive me if this has been asked already. I've recently acquired a set of heat exchangers from a popular auction site that were described as "little used, 1.7/1.8 heat exchangers". I got them for a steal. Upon receiving them, I realized they had very little rust, and we're in great condition. And by little rust, I mean no rust except for the muffler flanges which had little to moderate rust (looks like it may have been leaking for a while) The shrouds were "shiny" as if they were made of aluminum? And the headers are discolored with maybe light surface rust or something? Definately something a little polish or scouring pad could clean and make shiny again. I checked it with a fridge magnet and the shroud was non-ferrous, and the headers barely if anything had any magnetism. Have I stumbled upon a set of well-used stainless heat exchangers or just a damn good set of originals? Is there a better tell like a stamping or something? |

I had looked at making these. I have the equipment to make the Header portion no problem. The issue has been the clamshells that are part of the heating system. I had spoke with John at one time about doing a group buy, but he wasn't real interested it setting up to do these at the time. Honestly, if we could do a group buy, that may be the way to go. If these is some interest I will try to work with him to see if something can be put together.

I'm interested in participating in a group buy for a new set of 2.0 SSI heat exchangers. I'm curious to find out what kind of deal we could get. It seems it's been a few years since John produced SSI heat exchangers. I believe there is now enough demand for replacements that it would be worth his while to produce another hundred sets or so.
