im looking for some more opinions o what size primaries and collector size i should use for my single 88mm turbo project it has brodix t1 heads on a sbc. i was thinking either 13/4 or 15/8 with a 2.5 in crossover but im not exactly sure what size the exhaust ports are. car is not here at the time. any help would be great thanks.

Both primary sizes are more than big enough, just go with whatever is able to cover the exhaust ports all the way. 2-1/2" crossover is more than enough as well.

Depend on what size motor since your looking at an 88mm it must not be too big (engine).
