09 Manual Trans into an 06?
Ok I did a bit of searching but didn't come up with anything,
Does anyone know if an 09 manual transmission fits into an 06 car? is it a direct swap? or some minor mods needed?
Thanks!

Direct swap.
Highly recommended for many reasons.
The only negative I am aware of (if you want to even bother calling it a negative) is that you can no longer fill the transmission fluid through the shifter, which made the S1 fluid changes a breeze.
Other than that, you get an all-around improved transmission with better gearing (increased acceleration 1-5, lower cruise rev in 6th) and it's more durable to boot.

I doubt it, the girl at my local convenience store acts like someone ***** in her corn flakes each and every morning.

Wish I knew this last week.... Just finished changing it and I had to use this pump thing to get the fluid in. Kind of annoying

Yeah, it is. Far easier to just undo the center console shielding, remove the 4 screws, pull out the shifter, pour in 2 quarts. Replace items. 
Can't do that with the diff though

Thanks for the input guys!
I have been doing my trans oil changes at a local dealer "tech day", they let us use their lifts for an afternoon, those guys are awesome.
so trans oil changes have been a breeze for me, I've been doing them once a year.

In that case, check out this post:

Doesn't sound like you are racing, but should help your decision making on that 09 transmission.

Dump the trans. Run it anyway. That piece of **** will last two weekends if you baby it. Put a rental driver in it and it will last one weekend. We use to run two per car per weekend in Grand-Am. Cheat. This trans design is totally flawed. We would do serious repairs after each weekend. Always the 3/4 synchro. The 3/4 shift fork is the weak link and there is no fix. Trust me. Lobby to get the new trans or just run it. It is near bulletproof. The input shaft is about 50% smaller but the thing is like a rock. At one point I owned 7 pre-09 transmissions. The new one will pay for itself in one season PLUS you'll have to baby yours and I don't know about you-----do you baby stuff when your racing for or defending the lead?

The 20b guys go with an FD transmission, which is stronger than either RX-8 transmission.
The strength Eric is talking about isn't HP/TQ strength, but internal component strength. Shift forks, syncros, etc...
Basically the things most likely to get screwed up by someone using a shifting technique that is hard on the transmission. Has nothing to do with power.

More than OD's S/C? Though Eric's NA isn't much farther back in power, and quite a bit harder on the transmission.
I don't know about any of the other boosted guys. The 20b swaps haven't (can't?) that I have seen.

Just to clarify... its not really a "direct swap" because the connectors for the neutral and reverse switches are different.
So you'll need to install new connectors/terminals to get this to work.
I did this swap a few months ago on a local's car and just used quick disconnect terminals.
To make sure I didn't cross my wires between switches, I put male ends on one switch and females on the other.
If I had more time to prepare, I would have bought a better weather-proof connector and installed pins.
But so far its been holding up just fine.
And its bulkier... so its more difficult to reach up the side of the tranny to reach the slave cylinder.
So its best to install that while the tranny is a low as possible, then lift it the rest of the way up.
