Wow...93 views and only 1 comment. After lurking on this very slow forum for over a year I feel I must add something. I hope to be in an F in a year or so...having the first Supercharger installed by TRD in my Landcruiser in 1997...this is very exciting news. A supercharger is a bulletproof system. Not sure what is needed other than the ECU and possibly larger injectors.
It would be nice if TRD offered it..but good news nonetheless. So there you have it...now two people who are interested .-)

I'm guessing 5-6 psi with the stock internals............good mid range/top end centrifugal unit. They really shine top end......I've been an E46 and a C6 Corvette with these units. Pretty loud whooshing noise from the BOV.....but that never gets old.
Intercooled?
Cool stuff.

Fuel pump is usually not a bad idea.

Yes, the system will offer an intercooler. *Edit, it looks like it's an air to air intercooler.
I'm with you regarding the blow-off valve. I don't care what anybody says about blow-off valves. I love that whooshing sound too haha. Some make crazy sounds like the HKS SSQV whistle. I like them all.
More info directly from their website....use your browser to translate

Tuning is the main hurdle for the US spec RCF/ISF and now the GSF.
This topic has been debated, discussed, and horse beaten to death for YEARS on the ISF section. And even today, there are no options available. Whats done in Japan is not easily transferred over to the US counterpart, because the ECM in Japan is open and does not have complex encryption keys. The USDM ECM is impossible to crack. And to top it off, the ISF has +14 ECUs that communicate with one another...so if one fails, the others will not operate properly. It gets more complicated with the 8 speed tranny with its own ECUs. Also with Lexus and their acceleration lawsuits, you would think they more likely made the ECM/ECUs even more complex...they do not want anyone messing with it or anything attached to it. So a simple piggy back will not work either. I just can't image how much more complex the entire system is now with the RCF. Lobuxracer can give a more descriptive detail about the entire system and why it is so complicated to deal with. And just because a big manufacturer like HKS is making a system in Japan, doesn't exactly mean they will cross over. Sure, they are a large company, but so is Greddy as you mentioned, and they also developed a supercharger for the ISF...which today, led no where. The bottom line, they couldn't tune the USDM ISF. And the market demand as of now still looks bigger for the ISF than it does for the RCF, and nothing has come out beyond I/H/E since 2008. For those that are just stepping in to the Lexus lineup and RCF and are thinking of force induction, do some research around the ISF section, and you will see the extent of whats been done, and where it has failed.
Sorry to be a party pooper, but it is true. In order to really modify the 2URGSE engine for serious gains, it must be a complete buildup. Higher boost doesn't work well with the DI, so some have removed it, and would require a revamp of the entire fuel system. Also the pistons, which are designed for DI, also did not hold up well to boost..so a piston swap would be needed there. And the complex tranny can be subtracted from the problem by installing a standard manual transmission, which also has been done and proven to work. To get away with the encrypted and uncrackable ecm and ecus, a complete standalone can be added, but expect to lose all other luxury and performance features inside your car. But on the very brighter side, there is a belief the JDM ECM pops right in and could work...from there you can tune just as you would with any Japanese aftermarket part.

I still fail to see how a piggyback cannot end around the signals being sent to the ignition, fuel, etc. It has been done on a lot of cars in the past that does not require modification tot he stock ecu. Obviously a tuned eco is optimal for precise tuning but for many years the tuner market ran off of the alphabet of piggy backs (itc's, arc's, aic's, etc ).

tired of people acting like the ECU or ECUs are uncrackable. and there are 3 including mine Nitrous powered cars putting down 150 more whp than stock. I know boost is different but its the same idea. With there being the RCF GSF the new ISF and the LC500 sharing the same powertrians. Our options will open up. The RCF is already exploding in aftermarket popularity, And social media has alot to do with it. This thread is going to be back and forth with a bunch of internet bench tuners. Lets see what happens, and stillen is working hard right now on the IS supercharged format. I personally wouldn't buy a GREDDY kit for any car but that's just me.

Explain to all of us how its done? Whats the work around for a 'complete' tune. A lot more involved in tuning with force induction than nitrous.

as for the nos vs or forced induction difference i was referring to the strength of the motor. took me an hour and a half total time to tune my nitrous set up
