BTW... i tend to agree with the other posters... for you SRT-6 guys, this is not a good idea... there are parts already out there that will give you the extra horsepower you require... twin charged vehicles are not very reliable (just ask the owner of the twin charged MR2 in ultimate car challenge of SCC from two years or so ago) as there are many points that can fail... add the fact that the turbo is hanging by the rear axle... thats one expensive muffler to bottom out on road debris.
but, it is the perfect route for me as this is just what i do and have always done... custom fabrication is my passion/hobby.
