For those of you with the 1PZ 5cyl engine needing a bit more grunt I can wholeheartedly recommend the AXT turbo kit.
I've just finished installing it and it transforms the performance of the truck!
I little bit of tweaks needed here and there as it is originally intended for the 6 cyl 1HZ but nothing too drastic.
I can see some mud-plugging coming up this weekend!
