nah, i'm sure you haven't upset anyone, i'm just thinking that if some people can get away with posting WTB's in other sections, then the 30 post rule is overridden, and we might as well not have it at all. maybe changing the topic from a WTB to a "Where can i find a good condition motor for a .... etc etc etc"...
as for some direction, you may actually find your best bet is to find a similar car with a mechanically okay condition and just do a transplant. and while you'll have a shell left over, you can either part it off yourself, or just get a wreckers/towing company to come pick it up for free. check ebay, they always have lots of r31 pintara's going for sale
