Can you swap a GS 300 motor for a 400/430 motor
 

I have a GS 300 and was wondering if I could swap the motor for GS 400/430. If so what is involved in the swap? Do I have to change the computer and transmission? I tried googling this, but nothing came up. Has anyone anyone ever done this?

Never mind. I found the answer. I guess it isn't worth it. I didn't know you had to change the E-shift and tranny.

If you're looking for more power, you'd be better off turbocharging your GS3.

Or Aristo swap. :)

if you wana swap aristo is the way to do it direct swap

money and time will allow anything to happen
and like the other guy said, itd be more worth it to just turbo your 2jz
