i don't like some of the ideas you have on your shopping list.
why keep that dog ass ls tranny? it is a budget constraint?
a stock ls or stock b20 can take 14psi, so if you had one like that and ran 10psi all day it would be a lot of fun. get an obx lsd for cheap and a turbo or blower for all the tq a honda can't put down to the front wheels anyway.
oh yeah, for turbo don't go less than 3" on the exhaust.
