What turbo will get me to 400 horse but will still be good for drag racing? Im trying to ball on a budget so keep that in mind. Right now i have cp pistons, eagle rods, stock head, .57 trim ebay t3/t4 cast manifold, IC 2.5" thick. 20x6.5" w/ 2.5inch piping and precision 880's. Where in this setup can i pick up some power and also what turbo for my goals?
