Oh dear, where do we start?? Not sure about tassie, but up here you can buy a decent 4age engine, gbox, loom, computer combo for about $1000ish, depending where you buy it, and people you know. Ive never heard of a K90???? And i think TWINKY added a little sarcasm with his post about lifting the body, read it again you might get it. There are 2 main reasons for lowereing a car, looks, and handling. Another thing about doing a 4age swap, it will slide right in, but you will have to do a bit of messing around with wiring. And an electric fuel pump setup. After spending 3.5 grand on it, you would have been better off buying a twinky.
