I got this XR3 manifold a few months ago
After two weeks in vinegar and about 10 mins of wire hand brushing
not to bad - its coated in oil for now - as i need to find a XR3 downpipe (double) and adjust it to fit the single SS1 down pipe.
I got a good deal on a set of TBI's and Megasquirt kit from a CVH setup, the seller managed to get it running but went another direction. Pictures on the parts page
It needs some more bits :
1.Trigger wheel, sensor and bracket
2.HP and LP pumps and fuel lines.
i have not really looked at the kit yet but it will be destined for a spare engine most likely.
