Checking the jap auction sites, the price they go for would making $15K a reasonable figure for one. If you are buying locally from a yard or privately, you will pay more.
I bought mine through autoworx, cost me 260,000yen direct from the auctions. I didnt enquire about Series 2 turbo manual sedans as I didnt want one, but surely they would only be $3-4K more than a series 1.
