ebp 99 si

i finally get to trade my si
for a 96 hatch w/ lsvtec
here's the set up on it but i want to go turbo
current setup runs 13.2 on street tires
so what all will i have to change?
i know i'll have to get rid of the pistons for some 9:1's and get some skunk2 turbo cams but i was wondering about the block
once a block guard is in can you take it out?
i wanna get it sleeved so can i reuse this block or should i just get another block?
block:
95 LS
je pistons 12.5:1
total seal rings
eagle rods
block guard
spoon chipped P28 ECU
head: GSR
skunk 2 valve springs
skunk 2 retainners
skunk 2 intake manifold
aem cam gears
skunk 2 stage 2 cams
sx fuel regulator
apexi n1 exhaust
si gauge cluster
