Engine Turbo setup help

Turbo setup help

I'm looking to boost but I'm looking for a good setup not only for the turbo but for the entire motor from headers back exhaust replacement and internal work. I need information on turbos with good spool up capability for a 98' corolla. I also need a good full exhaust(headers, cat, pipes, and muffler). NO CATBACK EXHAUST, I'll need the whole thing----back-pressure is a bitch. For Internal work, what kind of compression do I need. Should I keep the same compression ratio and replace the pistons with better forged pistons and connecting rods or should I drop the compression. Any extra information providable, please share. I left the corolla community a while back and swithed to honda but I just finished my hatch. Now I'm ready to finish the corolla and I'm looking to finish out strong. Thanks.

You don't need header (not headerS) if you go Turbo.
So if you're planning to turbo, just don't waste money on header.
And what do you mean "NO CATBACK EXHAUST"??
