What is the best twin turbo kit for an LB7, also, I was told I have to modify the position of the dual cp3 to fit it?

People have seen good luck with the MPI kits from Nathan at maximized performance.
Ive seen a 11.80 on a ex cab lb7 with his kit.

Yes MPIs kit is top notch. Itsa very very nice kit. Its proven well putting stock motor trucks in the 11s when tuned right.

You wont need to modify the postion of the twin CP3 it is nowhere near any of the plumbing for the twin kit.

There is also the II kit which is cheaper than MPIs, let the flaming begin.

Or you could make our own.

The Industrial kit is only available for the LBZ/LMM currently. The MPI kit is top notch, almost looks factory. PPE is rumored to have twins in the works also.

It's not required, but if you want more air, Go for it!! The PPE turbos are a bit pricey IMO. Look for a Borg warner S300. Durallymax can point ya in the right direction to have one spec'd for your truck and application.

MPI for my truck starts at $4500, I specifically bought a rolled over truck so I can afford all this.
