1. for the crx id just go with a B series just so it bolts in easy, JUST incase that wasnt clear.

2. if ur going to boost, id go with the 94-01 LS b18b because it comes with lower compression and higher torque. lower compression= better for boost because there is less of a chance of detenation (there is ALWAYS that chance if proper precautions r not taken) then the low end torque=faster off the line then +boost > boosted gsr

3. the boost for high end + low end torque (already in b18b and will b greater with boost) is perfect for all around power on the powerband. unless u just want boost+vtec for highend only which would just make u play catch up... and u wont b able to h:
