As a drift fan, and a Jeep fan... Don't do it... That's where I'd be leaning.

The only car I'd put that cash into is an ae86. IE the mid-80s corolla gts twin cam. Like has been said already, you could do the sr20 swap on a car for cheaper plus quality performance components all yourself and save a lot... And it'd be your design an handiwork.

Plus its a lot easier and cheaper to find places to Use a jeep than go drifting.
