I just got a LS400 SHELL for free. It's super clean and has everything but the 1UZ. I want the air suspension. I've seen people mod it to fit other cars but I haven't seen anything on a 300.

I was considering keeping LS because it's alot cleaner than my GS, but still in the air.

What parts can I use that are compatible?

 

I believe the fuel injectors from the LS fit the GS

 

If I were you, I'd sell the parts off of it on Ebay individually. You'll make more profit that way. LS400 owners really need those parts too.
