Shame I only have this picture with the exhaust housing covered and the compressor cover.
I remember seeing an advert posted by steveL on renault5gtturbo.com around 2008-2009 about the stuff c.r turbos were making years ago, ok they may have not actually cast them themselves (maybe got a foundry to do it) but were the only people at the time I talked to who could offer a proper cast .49 housing, also who ever the owner was at the time when I brought mine was a bit of a boy and well up for a deal with a bit of cash, other ex housings I saw on a rb unit I owned were a .49 housing but was made up out of two housings welded together.
