Turbo six on a Budget

good round cylinder walls are a must for any hp build n/a,blown, or turboed! if its all blowing past the pistons its not gonna give desired results! basic hotrodding 101, it all starts with a properly prepared cylinder block even if using cast slugs! ant no sort cut around it!!
In my gut i knew this i was just hoping to get around the machine shop cost. Look over all your comments i am realizing that is going to be more that expected what is a rough estimate (I can google prices all day but there are hidden costs and with everyone here being more experienced than me you will have a better idea at a rough price)
