No disrespect fella but IMHO I think you'll be lucky to ge over £500 for that, and with a T4 on there and not having been setup it will be detonating like mad at 12psi so the engine is a ticking time bomb mate
I'd spend £100 on a setup and sell it with a nice printout, at least then buyers will have peace of mind that the engine is not going to blow and know that it's making good power.... if a bit laggy
