Nissan Bluebird zx turbo with a twist

Ok so I have a Nissan bluebird ZX turbo, has been converted to a ca18det from a Nissan 200sx s13, was on the road for a few years like this til the head gasket blew, got another engine to go in that is a runner, has a full custom stainless steel exhaust from tubular manifold back. Still runs now but obviously will overheat. Bit of a rushed thread as I have just found out I need to get rid of everything. Some people may recognise it from ZXOC as it was Hitch on there that did the conversion. If anybody can give me a guide price on what this may be worth that would help alot.
