From what I have read, most people ask what the goal is in horsepower when it comes to picking out the size of turbo.

Is that the only thing that you go by to determine the size of turbo you get? I looked in the FAQ but I did not see a thread that helps determine size of turbo.

 

Setting a HP goal is a start.

 

Ok, that is what I needed to know. I am building a b20, and I do not know what the all engine specs will be before the turbo. So it makes no sense for me to worry about figuring out a turbo now until I know where I am.

Thanks
