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".

Yeah, but that costs $$$$! Shocked 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! Grin

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

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 ...

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.

Your car has had the tubes cut off the heater channels.  Just put a hot potato in your jacket pocket.

There are also heater muffs available for aircrafts that just clamp over your existing j tubes
