Hey Guys, I have a 2001 4Runner SR5 sport with 225,000 miles. I am the original owner. I have a want for more horsepower and torque since I have larger tires now. I was thinking of a supercharger or doing a v8 swap. I know that with proper maintenance, I can get 300k - 400k miles on my 3.4L, but putting a supercharger will bring out any weakness I may have. This is what made me consider a V8 swap. Any tips or suggestions? Thanks.
