I brought my 6 speed XR6T in 2006 since then ive done the mods as follows:
Full Atomic Motor, including 650kw rods, atomic pistons, atomic 276 series cams, valve springs etc..
Nizpro plenum, Nizpro front mount, with custom cooler piping and CAI
Modded Wastegate, with 12psi actuator
Full xforce exhaust, twin 2 1/2" series one....
Twin plate clutch..
Seimens 60lb injectors, walbro 500hp intank pump, 700hp external feed
Theres alot more done, but i cbf typing.
Its currently making 377rwkw on 17psi, but it has a manual bleed valve, as soon as it reaches 4000rpm, the boost bleeds off to about 13-14psi.
