Motor Specs Difference between '09//12 RL and TL
According to Wiki, the TL shows it has 20 more HP than the RL. The engine is identical.
The specs are identical. What gives the TL 20 more hp over the RL's motor? Is it the cams?
Also, the 2011 + RL have the 6 speed transmission, is it worth the swap over my '09 trans?

math is off?
I see a 10hp difference between the two you listed...
but then HONDA says this.

In addition to developing improved power and torque, the RL engine meets tough CARB ULEV-2 emission standards and delivers good fuel economy. The RL's engine bay appears more upscale thanks to a new surround panel assembly that reduces visual distractions and focuses attention directly on the all-new 3.7-liter V-6 engine.

that closes the gap to a difference of 5HP.
so, now you have to think which one is the more intended sportier car?
not the RL as the RL is more a luxo cruiser
we can attribute the 5hp difference in the TL as part of the ECU tune.
it's obviously tuned more aggressive to be sportier than the RL

How about swapping the transmission? I'm thinking it could bolt up but not sure if there's other requirements needed to make this possible.

I personally wouldnt mess with any swaps unless my car was paid off and the value of the car is less than lets say $5k.
you're asking for trouble when swapping mechanical components on a car that has a lien on it. you're going to absolutely KILL the value of the car if its worth or valued at anything above lets say $10k

It's almost paid off.

Don't you need a new ECU that knows there are 6 gears?
I also second the fact that the 3.7L RL makes 300 HP. 5 HP difference.

The power difference is definitely in the tune. The only difference is that the TL has 2 sets of part numbers for the cams, which more than likely means the 6MT has the more aggressive cams. Except for that, both motors are as identical as it gets.
As for it bolting up, there would be ZERO issues. You would however HAVE to switch the engine harness/ECU with one from the 11-12' RL.
I've contemplated the 6spd auto since the 5spd is getting more depressing by the day but my focus is directed towards 3 pedals…

Weight?
…doubt there's much of a difference.

The main - and perhaps only thing - that differentiates the RL's 09-12 or KB2 from others is the vtech on exhaust as well as intake. all others its intake only.
Plus better drivers of course.

No I was thinking total car weight. but maybe that doesn't factor in HP rather 0-60. My bad.
In any case Sami I don't know which wiki page gave you that info since the KB2, or the 09-12 you're quoting, is listed at 300 HP.

I got the info from Wiki. Thanks for the info!

That might be a headache. Why would you have to change the entire engine harness? There's no piggy backing for the ecu? Just curious.

Honestly if you really want to feel the difference in hp, go from 295hp to at least 360-370hp ... anything in between will give you very little or none feeling that you upgraded... TL is a differently intended car with different target audience: more tighter suspension where RL is more plush, comfortable ride.
