I say do the ls swap. Fun, reliable, instant low end torque, minor mods will create even more POWER, FUN!!!!!
Anybody else who says otherwise
A. cant afford it
B. automatic "hater"
C.GayDM confused
D. trendy follower
E. sucks at life
The bottom line is you should always tune your car for ear to ear smiling. And always have the most FUN behind the wheel possible. Enjoy driving your investment instead of repairing it frequently. Plus the swap can be legitimized.
Good luck.
