10k is NOT worth it, at least not to me. the car would be faster, but not "oh $hit" fast.
you'd be better off selilng your RL< and then putting another $10k toward the purchase of a newer/faster/better car - AND yo'd get a warranty.
grab a low mileage used RS4 or something like rthat if you want a bad a$$ uber sedan. yeah, not as big as the RL.... but then get an M5.... you can grab us used M5s for $50k easy, maybe a bit less.
if and when I ever sell my boxster, I'll let the RL go and look into some hardcore sedan like an RS4 or M5. right now, I prefer having one car for JUSt luxury and one for JUST fun/handling.
in the end, i'm cheaper than buying that M5 too

Yeah, 10k or even lets say minus the 2k for the rotors/pads/a-spec suspension 8k is not worth it imo as well. But I say its still bad@ss cuz its the first I've seen for an RL! If I had money to throw around I would. But in this econ, no way.

Not for nothing, but a properly tuned turbo setup with quality parts and fabrication will run you in the 4-6k. Considering he didn't do any of the work himself, the shop had to do research n modify things, plus the other things done 10k is reasonable.
Like the old saying goes...." You gotta Pay to Play"
not to mention being the first is always going to cost more until it becomes a little more mainstream.

The kit is 4k online if you have some decent knowledge mexhanically you can install it yourself its really not that hard only two very minor things need tobe modified.... If i wanted to i could have mine supercharged for 4.5k i bet.....he paid alot in having it done but you get what you pay for and they are a quality shop...i bet he paid 4500 for the kit, 250 for the battery, 800 for the aspec, 500 for the brakes, few minor things so he paid again just a guess but 6500-7k in parts and 3k for labor... If you cut out thr labor and shop for parts you can save thousands

I was turned to this thread by a fellow member. It's pretty cool what you have done.
I know that the AWD gen RL has massive drivetrain loss. When did they go from 3.5 AWD to 3.7 AWD? Did the power nnumbers change or just the Tq?
227 FWD proves its good for around 280ish crank hp. Going over 20 % is really being generous for a modern style higher end auto trans. I recall they originally came out with 300hp then lowered it to 290, I think they need to keep going down. What are the TL-s putting down with the 3.7 FWD? should be the same engine right?
10k is steep, but it was a custom job. 270whp is ok but, if you can push 6psi it will be much better and you'll get used to it. If this car ran a 13.8, I would be shocked.
Arent there any reflashes available for these cars? What about the FIC from AEM? Should work. MAP or MAF on this RL?

Welcome. I have been following your exploits with your 2G Legend for years. The 3.5 engine swap was a masterful job...in fact, it is Legend-ary!
The 3.7 L 300 hp engine was introduced in the 2009 RL MMC. The RL and the 2010 TL SH-AWD are the only J series engine that boasts VTEC on the exhaust side. The 300 HP 3.7 in the MDX or the ZDX do not have this feature, at least according to the technical releases on AcuraNews.com.
The RL and TL SH-AWD engines are slightly different with 300 HP and 271 lb-ft torque, 305 HP and 273 lb-ft torque, respectively, with both acheiving those peakes at 6300 rpm and 5000 rpm. While the exhaust side VTEC is more complex, and expensive, it is not clear what the extra benefit is. In the case of the RL, 1 lb-ft more torque at 500 RPM higher than the MDX/ZDX engine, and in the TL SH-AWD, 5 HP and 3 lb-ft more torque. We can only guess that the HP and torque curves show some benefit that the spec tables do not really show.
The RL is also the only SH-AWD implementation to include a more complex "acceleration device" which can overdrive and vary the rear wheel speed over a 5% range with respect to the front wheels speed. All other SH-AWD implementations delete this third planetary gearset in favor of a fixed overdrive of the rear wheels, about 1.7% faster than the fronts, IIRC.

Almost a Year later:
The Modifications were well worth it.
The Supercharged RL with ASPEC Suspension and upgraded brakes is a blast to drive.
It takes a few months for the computer too really figure out how to use the Supercharger.
There is a definite change in the power of the engine when the SC is installed and it just keeps getting better the more you drive it.
I am sure the Dyno readings will be much higher, the car feels much faster than when I the SC was first installed.
Imagine, if Acura did a Factory installed supercharger.
My Gas mileage is unchanged @ 17 MPG.
The RL is a nice family car- My RL is a fair competition for a BMW 550 or an Audi 8 Cylander car.
An RL is definitely less costly to maintain.
A Cost effective solution.
The Car has the correct proportions of performance and reliability.

have you had to smog it yet? are you in CA?
here in CA... I would think this would screw you trying to smog it.. unless this kit is CARB exempt.. and I doubt it is exempt ON the RL.. it was a TL kit... so it's not the correct application as far as the smog people are concerned...
I agree with you - Acura coudl have done this from the get go and actually MADE a serious competitor to a 550i...

In the Acura Legend community we have a pair of craftsmen that retune the ECUs for better performance depending on what modifications are done to the vehicle.
Is there anyone that does this for the 2G RLs?
I think that would help out loads!

i still haven't heard jack $hit about CA smog... which you will flunk.
unless you want to start geetting illegal smogs and run the risk of getting a huge ticket and fines - this is not worth it in CA.
plus.. if you were unlucky enough to blow up your motor.. Acura woudl shove this up your a$$ in the warranty department...
this is a big fat waste of money. sell the frickin RL and just buy a faster car.. geez.
I could sell my RL, and buy a CPO M5 for $50k, an RS4 for $45k, and while I might be out of pocket more money than spending $8k to mod the RL.. in the long run.. to avoid all the headaches of a highly modded car that the dealer won't work on, won't be under warranty, won't pass smog... i would be far ahead..
i've been down the modded car road.. i speak from experience...I had a 2004 S60R and sasnk almost $10k into a body kit, chips, downpipe, exhaust, intake, suspension.. it was fun, but in the end, the car was finicky, the dealer gave me crap, the warranty was out the window...and in the end.. I would have been better off to put that $10k into just buying an M3 in the first place...
sorry... you may not want to hear it but it's true....
do'nt mod the RL into something it's not..

^ and thats your opinion and your entitle to that. but u really sound like hater. this coming from someone who wanted 19s then 18s then 19s again. then wanted h&rs or aspec and settle for some tires...... this guy can say he has a SC RL and not many people can say that. funny how youre into mods but u cant appreciate this. just my 2cents.
