While turns 4 and 5 can be done with sub-90 gear, they are a huge jump in difficulty over turns 1 and 2.

They both require a reasonable amount of skill and gear. While your gear may be more than enough to clear the content, most random groups aren't going to be willing to gamble the time it takes to clear it with sub-i80 members.

If you want to clear turns 4 and 5 without hitting i85-i90 you will need to find a static to invest time taking on these challenges at a higher difficulty.

If you only intend to clear them with random groups I recommend working toward i90 in the class that you want to clear them with.

Having more than one class available to play endgame content does not entitle you to a party spot in the most difficult runs with a sub-optimal build.

EDIT: Just start your OWN group on the party finder with a lower ilevel. Don't worry about what other people want in their groups. If you still can't clear it afterwards, consider upping your gear if you want to have an easier time grouping with randoms.
