The main drawback with purchasing a project car in pieces is that you don't always get all the bits...

I received none of the heater components for my Vixen S3 except the duct tube that sits into the front arch moulding. Here's where it gets interesting. My chassis has the "front extension" to mount the heater fan in front of the radiator but apart from that I know nothing else. I'm aware that the cars had various solutions to heat the cabin over the years including bespoke TVR heater mouldings (rocking horse I presume) - but what I should be looking to put back in?

Heres what the firewall looks like...



Thanks

James

James your firewall is configured to house TVR's own heater matrix. Essentially the round bit has 2 holes in it to connect a boss too for the heater air ducts. a square fibreglass moulding approx 2.5" deep covers the hole in the engine bay which has space for the matrix to be mounted. 2 pipes stick out of the moulding which bolts to the firewall which you connect the hot flow and return to. On the moulding itself is another moulding which forms a 3" boss to connect the cold inlet duct to. A seperate fan can also be plumbed into the duct within the engine bay to blow air through the matrix.

Someone will hopefully post a piccy.

This version of the heater is known to be the poorest one but is the best one to use if you are shoehorning a big engine into the bay.

Earlier cars used the MGB heater which can be purchased from Ashley Hinton brand new. If you go this route though you will need to cut the hole out and glass over to make a flat firewall.
