52mm or 58mm TB
Ok right now I have full bolt ons, with 1.6rr's and just ordered the nitrous outlet 52mm plate kit and plan on spraying a 125 shot, in a year I plan on a AI H/C package, will the 52mm be a restriction in my case? How much hp would I be leaving in the table with a 52mm vs a 58mm? I have a BBK/edelbrock 52mm on my carby the way.

On a N/A with NOS & Stock internals you should be ok with a 52mm even with a AI H/C. When you stroke them and spin them faster is when you need the bigger TB. Strokers cycle more air though the engine, and when you spin them well over 6k is when the 58mm helps keep intake restriction down. Still depends on the actual setup.
