What is this TV show?

I saw it in Toronto, Canada about ~8 years ago, on YTV (I think it was
YTV, the main TV station for kids/teens.)

This show is NOT animted - it is 'real' (all of it). The show is about
a bunch of regular teenagers who go into one of their basement, and
then get sucked into a computer 'game', where they drive
transformer-like vehicles, and can also merge them all together to
form a larger unit (just like in transformers.) They constantly battle
enemies like giant Godzilla-like villans in the 'arena' (it's like a
building with circuits running all throughout it.)

Thanks in advance! If you need any more details, then please just ask
and I will happily give them to you if I remember them!

I have been wondering what this show was called for many, MANY years now.

Thanks!

Could the show be ReBoot? ( ReBoot is animated though)

Could it be the (Mighty Morphin) Power Rangers?

"Often, before a monster is defeated, a monster will grow into
gigantic proportions, forcing the Power Rangers to use gigantic
(bio)mechanical machines known as Zords. In many cases, these Zords
can be combined to form a more advanced (and humanlike) machine, known
as a Megazord."

Not Power Rangers, and not Reboot (although I used to watch both, though.)

The show that I speak of is definitely much lesser known, otherwise I
would have already figured it out. Shows such as Power Rangers and
Reboot are fairly well known so I know them much better and therefore
remember them well; also, just like Beast Wars, etc.

Well, Code Lyoko is kinda like this, but it isn't live action...

Premiered in Canada on "YTV" on Saturday: September 11, 2004 at 8:30 A.M.

It's kinda a 2D cartoon with 3D digitizing affects... 

Well, that isn't 8 years ago. 

Other robot things are Voltron, but ... 8 years ago digitizing?
1997... This would probably be ahead of its time...

Animorphs is likely (1998)

websearch of: ytv 1997 site:www.tvtome.com
 is inconclusive.

This is a free comment.

I'm not 100% if it is 1997, though.

It's not precisely digitizing, either. I believe the effects were
similar to the ones in Power Rangers during the same period.

The show you are thinking of is called "Superhuman Samurai Cyber Squad"

Yep that's the one, I found it a few days ago. Thanks!
