piston does so in the cylinder. This is why an engine designed for a turbo has less compression.
Therefore, if you do a turbo to an NA, first and foremost, if you plan on using pump gas, don't expect to boost much more than about 7 or 8 psi. You won't need nor want any more than that. Car will still fly as the absolute pressure (boost, plus compression, plus ambient air pressure) will be similar to a factory designed turbo engine.
Others have done this, and I would suggest correstponding with Eric Heyse, who posts on here as 85SLED. His LPT converted Notch-back two door is a rocket and has been dialed back from, IIRC, 11 psi which was detonating to 7 PSI.
And as Shaun suggests, read Corky Bells Maximum Boost and also "Turbochargers" -- can't recall the author of that book, but also a very good reference.
Finally, good luck, and take your time. You will not be dissappointed.
