Luckily for us we are dealing with decent sized v8 engines, Even a bone stock smog 318 would make 300 horse at 3 psi or so. The plumbing will be the heart of the system and everything else can be swapped. The key is to get these on cars so all of us can play,whether it takes your 185hp motor to 300 or your healthy 425hp motor to 600+ EVERYONE WINS . I think I will offer the kit in 3 different power levels ( fueling and supporting mods aside ) stage 1- stock to 450hp stage 2- 450hp - 600hp stage 3- 600 - 1000+ And the option for kit with no turbo and kit with custom turbo. This should easily cover everyone and you can trade up or down in a fairly painless manner.
