Small/lightweight Air Con?

[Ffirg 005]

The standard GM air con pump is too big to fit in my LS6 Cerbera build. Do air con pumps vary much in size & specification? Anyone know what I might get a smaller one off?

Classic Air?

do you have a link to your Cerby project?

Large variation in size and output, also try NF Auto's they have a kit used in their P4's and others.

I've got a Denso one from some sort of Daithatsu (sp?) on my car. It replaced a much larger Sanden unit and seems to work well enough. I didn't have a space issue, it was simply that I acquired the Denso with a pile of bits and it was in almost new conditon, whereas the Sanden from the original donor was in poor shape. Sadly, I now need to go back to the Sanden type as the pulley on the Denso is only a 4 rib belt, and I need the 7 ribs of the Sanden 'cos I'm fitting a blower soon....but that's another story!

Crikey... my dead thread's come to life!

Thanks for your comments guys, but I have now found a solution in the form of a 1990 Holden Barina (I'm in NZ) pump. Could be the same unit as GM fitted to the Nova there, dunno, but the comparison between the standard GM LSx one and the Barina one looks like this:



'vette pump: 205mm long x 135mm diameter pulley
Barina pump: 165mm x 100mm

No project page as such, but there are a couple of threads about it in the TVR Major Mods and New Zealand forums.
