I am also in the process of doing this. you need

Injectors.
Head studs
Fuel Pumps
HPOP
Definely a chip
Rods
valve springs
push rods
probably a gridle

you would also need a high flow intake
and to free up some room in the engine bay. It is a big expensive task.

oh yeah, your going to need a transmission and gauges to back everything up, atlest 3 for boost.

For a modest set-up (70 lbs) you will need to change your injectors to min 255cc, hpop, up pipes, down pipe, oil feeds, head studs, rods, recommend ceramic coatings as wells a spearco intercooler

80lbs - all the above plus it requires supporting modifications such as H11 head studs, fire rings, valve springs, girdle, and aftermarket rods, prods

90+lbs - 530 injectors

set-up with ceramic coatings is around $9000.00+, not including your fuel system upgrade and intercooler, and hpop

No problem. Once i get it done I am sure I will be down your way for pulls.

It wont be close to being done intill spring. I will have to take a short break when the snow plow comes out, but it will recharge my wallet
