Interesting. So not a good venture if trying to avoid added modifications... I mean, if I wanted to that is. eh..hehe Thanks for the links and info guys. I appreciate it.Yeah you can supercharged the 1gr but you have to use the FJ fit kit and tune it with the APR X-1. I'm not sure why TRD didn't make it for use on the 4runner or I would have bought that when I bought my 4runner. I would go with URD for the supercharger but overall though I would have prefered a turbo instead. just more efficient. the problem here though is the factory transmission can't hold that much power without modding it though IPT.
