Anyone know how much the Supra engines weigh?

I have a 944 Turbo, but have always liked the Supra TT- incredible performance & even more incredible potential... about the only thing I don't like about them is their weight. I'm wondering- does anyone know how much the engines weigh? Particularly w/the TT?

I LOVE the newer Audis (specifally the S4-TTV6) & BMW E36 M3's- would love to find a way to drop the TT Supra engine into one of them- even heard of some doing the LExus IS300 w/the TT engine- anyone heard of anyone dropping the TT into any Audi's or Bimmers? What about the Lexus IS300?

Thanks a lot,
Robby
