well, i think i am going to sell all of the go fast goodies and do a mild build. just rods, cut pistons and head studs. i will put my stock turbo back on and just run the stock CP3. not sure if i will mess with injectors if i have the money, i may just because it will be down that far already so i might as well. at least this way i will have both the motor and trans to handle some good power down the road and if i want i can always use some drugs if i want to go fast on the track....
I'd sell the Dual CP3 then add rods, head studs, and cut your pistons... that is good combination for 750hp probably more. I would never do heads just isn't worth it too me. You could keep your stock cp3 mod it and maybe squeeze 30-40hp out of it and still keep your twins.
