Quick Q's
 

How much would i be looking at paying, for a nice turbo cleanup/rebuild??

and ive seen some people get the turbo/downpipe sprayed with a type of like powdercoating, what is it called? what are the benifits? how much?

ok they where gay questions i know, and i found the answers already but here is another one im going to look into as well...

Im guessing im shouldent use the bolts you can buy at autozone, because of quality? Where should i get replacement bolts? and where can i get that tool to remove striped bolts?
