Question on a sale....

[Mellow 240sx]

I have a 89 240sx and i dropped a new ka24de in it...Wel I want to get rid of the engine and powertrain now..there is nothing wrong with it. I bought the car for dirt cheap and dropped the ka in b/c of money issues(wanted sr)..Well now I dont have that..the engine is a SOHC ka24de, its been taken apart rebuilt, new everything...pistons, head, crank,cam everything...even ignition. It still has the warranty on the engine also. Ive had it for almost a year and i only put 8000 miles on it. I dont race it so it hasnt been beaten on at all. I have had no problems with it at all. Its got Injen intake also (not that its a big deal) Well my main question is how much can i sell the engine and transmission for? The trans has 185,000 miles so i dont know if anyone wants that but my main concern is the engine...Please let me know if anyone can give a guess estimate on how much i could sell it for...Thanx
