i know people have modified j tubes into heat exchangers.can anyone follow this up with pictures please.they obviously wont give as much heat as proper heat exchangers but will take the chill off an interior for extra usage in the colder months.thanks in advance  |

cheers fabs.im presuming that they slice round the original heat exchanger and fit it to the merged j tube.the inerds of the heat exchanger wont fit though?

Not that it would work as well as the system Fabs showed on the Bergler, but an adapted non fresh air 40hp heater system, is another option. This was the type of heater system Keith Goss built for his '62 chop top.
Any photos of that Fabs?

Unless you see a challenge in making them yourself, there is no need. CSP makes them in 1½, 1 5/8" , 1 3/4" and even 1 7/8".

Real men build heater boxes themselves! But if you must, go ahead and buy them....  |

Yeah, but that costs $$$$!  Tiger does great work from what I've seen though. Did you order yours with the coating? My homemade ones didn't turn out totally perfect, but they should get the job done...I hope! |

Hi thanks all for the comments they give heat like original BUT off course if you have the big diametre of 48mms inside fins is less than original since outside of the heat exchanger remains same size you can not change that but our customers (mostly UK) are very satisfied with the heat AND combined with a big engine Gunter |

perhaps it's a dumb question but don't these heater boxes  require certain alterations to the merged header, and a fresh air shroud? edit, ok this type works with our headers i suppose, but still requires a "stock" shroud:  i would be more interested in the 40hp style like the chop top. |

This is a system built for Billboa by Doug Berg. Beautiful work, fits great and very detailed. I can't imagine it took less than several days to complete this ... Full 1 3/4" merged with dual 2 1/2" muffs!  |

That looks like a nice system-the down pipes on the heater boxes look like a nice addition and well at the extra material to support the dual mufflers. I bet it works pretty well!

I have an idea that could fit in this topic very nicely...
How about making a bigger j-tube from stainless stell, and then fit it in the body of original heat exchanger ?
Would that work ?

Some really cool ideas and images on this thread. Good to see people fabricating to enjoy heat and high performance for their VWs.

Just put a hot potato in your jacket pocket. |
