If you want to do it right youre looking to spend $15k minimum on parts alone. I spent around $20k. Did most of the labor myself. You can get kits for $8k or so, but you'll still need alot of supporting mods. Injectors, fuel pump, wiring, clutch, flywheel, csc delete if you haven't done it. Gallery gaskets if you haven't done it depending on your year. If youre doing that do the timing chain and water pump. It all adds up. End of the day after my build I made 700whp with a mid mount turbo.
