Just a few points: Bad30th, the gsr has a 10:1 compression, the Type R has 10.5:1 compression.
You can put a little boost into a honda, but not much. These are small engines with very high factory output, so there is not a lot of room to play around. The Jackson racing supercharger is about 5 lbs of boost, 7 if you get the upgraded pulley.
the b18c is an open deck, which allows great coolant flow but is not as stout as a closed deck. That is why some companies make deck guards or rings. Dayton or Dart, whichever company now makes b18 blocks that are closed deck and designed to be boosted or nitroused or whatever.

Peryn, you mentioned the mazda miata as a good engine to turbo. The compression for the n/a and the turbo 323 engine are way different. I actually had for a couple of years a 323 gt (sedan). When the turbo blew, I in my ignorance asked why the same engine couldn't be used without the turbo. The new mazdaspeed turbo miata only goes up to 178 hp, about a 35 hp increase.
