Randy: first step is to decide which rev- and boost range you will be using the most. You can then calculate mass flow of air (lbs/min) for that particular range and plot it into compressor maps of few different sizes of turbochargers you have your eyes on.

Goal is to keep the dot into it's most efficient range as much as possible troughout your "track pass".

So if you are going to drive from 4000 to 7000 RPM using 1 bar of boost, it's going to "eat" certain amount of air per minute (38 lbs/min @ 7000 RPM and 1 bar of boost to be exact).

Download the catalog of Garret turbochargers and check out which suits you the most. W/o really looking into it, I believe GT30R and GT35 will suit your need the best.

PM your mail adress and I'll mail you catalogs if you cannot find them online.

Thank you for your time,
