for two grand, you could probably replace the engine with another engine that is exactly the same as the one that came out,
that's about it (this is just my moderately educated opinion)
i would budget about 1000 bucks just for the conversion, at the least (for a 1ggte or a 1gge) as i don't think it will be a bolt in swap.
save your money more, you can always spend what is left over on mods (or essentials like food and beer)
Unless you are totally in love with the shape of the car, sell it and buy something else, like a supra of the same vintage.
