Sorry if i sound rude, but $4k sounds rather exy for a blow through turbo a15. I spose the gbox and tail shaft is valuable to ppl, but I think he needs to look at the $$$ if he wants to sell (I could be very wrong). I could buy a full forged short moter for my XR6T for $4.5k capable of well over 400rwkw. But i suppose its not a XR6T. Just my 2c though. Good luck with the sale.
