Startrek Voyager question

Is there a episode (or multiple that fit this), where advanced beings assist the crew in some major way (by restoring the ship, giving advanced technology, etc). If so what is(are) the names of them (and a brief summary of the help gotten)?

I know of one where Kes evolves to the next level of her being and is able to move them closer home, but is there any more?

There is at least one more. Some alien builds a sort of “space catapult” using technology similar to The Caregiver Array that brought them to the Delta Quadrant. The crew helps him finish it, and after Seven of Nine almost destroys it because she goes crazy, they get to use it and jump ahead many lightyears.

Ahh, found it on wikipedia, The Voyager Conspiracy.

And although it’s not aliens, in the episode Timeless, Voyager gets ~10 years taken off it’s journey from a future Harry Kim and Chakotay who were trying to save it from crashing after failed warp-drive experiment.

Wasn’t there also one where they get advanced holographic tech from the far future, that lets the Doctor travel freely around the ship?

What about the episode where they meet another Federation ship that was ‘getting help’ from aliens by torturing them?

Does that one count?

Also, future Janeway gets the Voyager all the tech needed to get home, like the armor and those ultra-hyper-technobabble torpedoes they use to blast effortlessly through a Borg armada; whether then returning home through the Borg transwarp thingy counts as ‘receiving help’ is questionable, though.

I also feel like there’s something with (a?) Q helping in some way, but can’t put my finger on it…

Equinox Part I and II, the episode I describe as “Voyager finds a fellow Starfleet ship fueled by aliens who poop anti-matter when lit on fire.”

Q offered to send them home in “Death Wish” if the Voyager crew would take his side. Of course, when it comes to getting home instantly or helping a superbeing die along with their chances, Voyage always picks the latter.

There was also a very early episode (like third or fourth episode) “Prime Factors” in which Voyager crewmembers illicitly traded some of their technology for some alien technology that was supposed to help them along. Instead of researching it and building their own version they just jam it into the existing engine and I’m pretty sure it blows up in their faces and they never mention it again.

The original technology for that was alien though, wasn’t it? That whole ‘quantum slipstream’ thing?

There was also the space-warp tunnel thing from the episode “Dragon’s Teeth”, though I am not sure how much does that help.

If I remember correctly, the Voyager also get some mileage from the quantum slipstream opened by the alien hell-bent on avenging himself against the crew of Voyager.

The holographic tech for the Doctor come from the episodes where Voyager went back in time to Earth and somehow find advanced technology. There something to do with the Temporal Prime Directive or somewhat.
