what problems would i face driving a race ported turbo FC on the street?

 

How do you define "race ported"?

 

if mazdatrix or bnr supercars rebuilds my engine and i pick the race port option over street port, what gains/losses do i have between the 2. im trying to compare them to see what i will go for...the car it is going on isn't driven everyday either...

 

maybe a half bridge or bridge port...nothing crazy
