Im starting to gather parts for my upcoming turbo project.
Problem is, I have no idea how to properly select the correct A/R.
Im definitely using a 76mm precision (or comp) billet wheel turbo.
Both sides will be 2.5" piping merged together, and a 4" downpipe.
Then it will split into the stock dual exhaust.
Since its a 4500lb car, I was thinking the .82 A/R is what I should go with, but then I heard I may have backpressure issues at the top end.
Since im totally clueless, any advice is appreciated.
