GS needs a turbo. When?
Yesterday (again) I extensively test drove a GS 350 and an F Sport. I love both cars. Solid feel, hefty steering, luxurious, quiet, good dynamics.
The only thing left me wanting is the engine. Don't get me wrong, it's a great engine with an even better roar, but my 328i (2 liter turbo) pulls so . much . harder from as low as 1,500 rpm.
After test driving the GS I invited the Lexus guy to give my 328i a spin. He was blown away by the engine and the transmission. At 2k rpm the 328i pulls like the GS at 6k. I know some guys like to rev the hell out of their engine, but not me. I'm hooked on turbos, the torque and gas mileage. And you guys must have noticed, I'm not even bringing up BMW's 3 liter engine ...
Any ideas, any rumors about a turbo GS in the future? I understand there's a new 2 liter turbo on the lil' NX. Maybe Lexus is working on a 3 liter turbo as well?

Toyota/Lexus seems to like to stay N/A for their engines.

So did BMW until 2007. Now I'm not sure if they even offer a non-FI engine. Lexus/Toyota are going to have to turn to forced induction if they want to remain competitive. BMW, MB, Audi, and Cadillac all offer turbo/supercharged six cylinder engines (in addition to turbo V8's). The GS v6 just doesn't compare for everyday driving. If you keep the revs up, the GS engine pulls strong, but at low RPMs the engine is pretty weak.

I expect we will see stuff later, once these cars start coming out of warranty period and people start looking/trying IS/Crown kits.
Right now there are a fair number of superchargers for the Crown Athleta and IS350, and I expect they would work with minor changes on the GS. 2GR-FSE - a quick google reveals mixed messages about it, I couldn't find an example of one, but there very well may be.
Basically, nobody has really pulled the trigger on doing it, so nobody knows. Go for it and report back.

Never mind - a quick scan revealed twin turbos being discussed here:
http://www.speedhunters.com/2010/06/...1_lexus_gs350/
So it apparently can be done and is being done - I'd honestly suggest reaching out to Mori, I've found people are very responsive with a polite email and an apology that you don't speak Japanese (unless you happen to).

The Germans are well known for their low end torque. The Japanese have always been about top end high revving power. A turbo won't change that. If anything, there will me turbo lag.

Some say the Europeans are great at innovation, while the Japanese are great at refining those innovations.
Life is a compromise - the more you have of A, the less you will have of B.
So at least the Europeans are great at the speed of innovation, while the Japanese are great at thoroughly refining those innovations.
Thus, the Japanese are slower to develop, but develop more thoroughly for superior reliability.
The Lexus modern day four cylinder 2.0L turbo has finally come.
I think there will be a V6 twin turbo in 2.0, 2.5 and 3.0 liters, and even a six cylinder turbo in hybrid gasoline-electric version, but it won't be released till the next generation 2019-2026 5GS, assuming the 7-year model cycle.
The next generation 5GS will certainly have much higher aluminium content than just the bonnet and lower suspension arms, and is set to shave off at least 220 lbs.
There will be GS V8's, but only as a niche model; not as bread and butter models...

IS 250 it's already the laughing stock, with 0 - 60 in 8s. That's Chevy Spark territory. I bet we're going to see the 2.0L turbo in the 2016 IS 250.
My guess is a 3.0L twin-turbo in 2017 GS. They nailed everything else, the car is light, nimble and handles as good as a E60 (prev 5 Series) - which says a lot.

They had a V8 GS 430 before but it wasn't making much more HP and it wasn't selling well so they killed it.

I thought I read, perhaps in the "Future of Lexus" thread in Car Chat, that the rumors of the 3.5L engine in the IS350 and GS350 being replaced with a turbo are running pretty strong. I'll have to revisit the thread.

After some thought, I don't think we will see turbos from Lexus - they have been using hybrids instead of turbos to boost output. I could even see a hybrid 4 cylinder being added the mix. Once the weight is under control, it will be better from a torque perspective since it starts at 0 rpm.
