does an LS engine take thevalue away from a1997 toyota supra? what LS engines fit?

2JZ-GE 16 and 2JZE-GE 16 ...3.0L in-line 6

Everything fit! Depend only how many $$$ you are ready to waste or spend!!! It might not take away value, but taking away potential buyers. 2JZ have a lot of potential.

It just depends on what you want out of it. Some people may want a drag car and for that, you can't go wrong with a big ole V8. If you want the car to maintain full value, though, a 2JZ-GTE is probably your best bet. It won't be the quickest, but it'll still scoot and having an original motor will help maintain any resale value.
