your post is kinda pointless. its like saying " i have a candy bar, what should i do to it "

first, a healthy ls is known to hold up to 250 horse (fwhp) on stock internals.
boost would be a cheap horse power.
ls all motor is pointless unless with a vtec head swap. lsvtec are known to leak oil no matter what. some claim that their lsvtec were built right, whatever - 99.999999% of all lsvtec leak oil.

a healthy ls in a crx should be hitting atleast mid 14s or low 15s anyway.
