I would like to put together a sts style turbo system for a 454 in a 1ton 4x4, an y suggestions for a specific turbo that would work, lets say 10 - 15 psi....What turbo is the STS 8.1 system? and how many psi is it good for??

 

i think the one parish is running now would have no problem feeding a 454

 

The 8.1l STS kit has a 76. Its good for 1100 crank HP.
