Looking at buy a used 64mm kit trying get some hp number on each turbo. Have you seen the the 64mm make 650hp or is that on a generous dyno? Looking to run low 12s on stock fuel and still be able to tow.
What kind of hp/performance gain is the 64mm? If I wanted could I just buy the divided housing and down pipe to run 366 or 369 if I already had the open housing 64mm turbo kit ?
