I've tried the 5.9
I have a 4x4 Extended cab and I tried to run w/ a 5.9l RT. I wouldn't say he handed it to me, but I don't think I will ever get him w/ it naturally aspirated. He slowly pulled away from after about 40 mph. I would say in a quarter mile he would've beaten by about 1/2 to a full car length. Well I'll find a blower, and I'll beat his A**. Haven't found any others that are a problem. The supercharged frontier can't run w/ me, I don't know why, but that truck is NOT fast. There's not tacoma out there that's beaten me, S10's ain't S***, and I ran w/ an Eclipse the other day, for a truck this bad boys got some serious balls. If I wanted something to race on pavement I would've bought a car, but I don't know of an RT that will go where my truck has been. I have buddy's w/ jeeps that had to turn around and go back while I kept going on some trails, I'll post pics later.
