Do you have any knowledge of easy ways to increase the power of the LS500 (V35A-FTS engine)?

I think it's easiest to change maps on a turbo unit, but you won't get much out of it. Do you know of anyone who, for example, changed the turbines to bigger ones?

I'm also wondering which stock components are ready for a significant increase in power and which certainly won't. I'm talking about the gearbox, the transmission, the axles, the brakes.

 

I'm thinking about a 4" lift kit for my LS. I want to stuff 33's in the wheel wells to do some offroading.

 

No unsightly wheel gap either!

"Hey, how is the road feel on those 33's?"
"oh man, the car rides like stock! Handles the bumps great and no road noise"
"really?"
"Thats right, they are not runflats!!!"!
"Do you keep a spare tire in the boot?"
"Not enough room, the bank of amps and subwoofers take it all up!"
"You added to the ML system"?
"Ripped it out, it was crap! Sure the detail was there but no bone jarring bass!
"for hip hop?"
"Nope, Im into death metal! I have the luxury package with the origami pleats that the crystal. " my mother likes the massaging seats in the back but her spiked bra keeps popping the air blatters!"She keeps snuffing out her cigarettes on the crystal. Thinks its an ashtray"

 

Generally people don't buy a Lexus, especially a new one, to make power/tune it. But I know burger tuning has the JB4 module for the LS500 that can change fuel maps to 91 or 93 octane, and they have an E85 tune. I don't know how the turbos on the 3.4L engine are controlled. You may want to look into the new Toyota Tundra forums because those guys are more likely to mod their truck for performance. Same block, idk what they changed between the Lexus and Toyota products, I'd imagine they are the same long-block, but either different cams for the trucks for more torque, or same cams just different tuning. If you had the JB4 installed, got larger turbos mounted, then as long as the fuel system can stand up to the output get a custom tune to send power to the moon! You'd probably want the LS500 AWD seeing as the RWD LS500/LC500 don't come with a rear LSD. Also, I think I heard in a video somewhere that this new TT 3.4L engine has the log style exhaust manifolds, where the exhaust manifold is integrated into the head/block design? I haven't seen anyone do a teardown on the TT3.4L engine to confirm. I'd like to see that video...

 

Sell it for a GSF?

 

We love our luxury cars but wish they drove like sports cars?
The mod dream.
Once upon a time I had a 2007 BMW530i, with MT. None sport. Read the Msport version in that year made rear passangers car sick due to adjusting suspension.
They'd give me loaners and try to upsale me. I leased that car, but I really fell in love with a non turbo 328 coupe, sport suspension, low to ground, staggered wheels, MT, and nice sport seats without the boy racer trim that came with subsequent models.
But it was a bit small after 5 years, so I got a 2013 535i (Turbo), Msport with MT also. Lovely car, but felt "big". I thought about doing all knids of things that would make it "sporty, more fun" but it would compromise the ride quality.
Really I wanted my 3 series back. I did not like the newer 3 series. It got big, lots of plastic bits and sport had colors and trim I did not like.
So I got a GS350 AWD Fsport. Grand touring, did everything very well, nothing exceptional which made it a great car! It took about a year but I really liked it.
I sold it because dealer made me an offer I could not refuse. I modified my GS to an LS. Faster, better seats, better leather, better sound, and totally modern interior vs. my 2020 GS! Apple Car play LOL!!!!!!
Now I drive this monster LS500. Its fast, but I don't feel it. The engine growls, but it needs to be fed in. Nobody else can hear it. Nobody really gives a **** either. Besides, that MS sound system is fantastic!
The seats, super comfy. Road feel? I have run flats. Why do I pay all this money and want to feel the road? The road sucks.
I have a sports car toy thing for the "weekend". We gonna sell it. We had our fun. Might be cheaper to get a toy then mod and change the character of the car if you want more fun car!
I get the F-sport option for those that want that. Might be a very good compromise to what the car is for those that want fun.
Im really content with the power of this car. I find Im not in so much a hurry either a lot of the time. This car is just really nice to hang out in. Why rush? LOL........

 

..... 🤣🤣🤣👍

 

Thanks for answers. I don't want a GSF because of the RWD. I don't think the engine is the problem. I think it's possible to change the turbines, change the maps and then even 700-800hp is possible. I'm more concerned about the gearbox. There is an Aisin AWR10L65 gearbox (right?). Gearbox modifications are difficult and expensive. Won't this gearbox crash at 900-1000Nm?

 

Yes; better keep it at 899Nm.

 

Swap a RCF/GSF/IS500 motor or even a 2JZ in it.. problem solved.

 

I would like to know as well. Don’t think I’ll add anything to mine but it would be nice to know. Only thing I’d like to add either have a custom cold air intake or exhaust. There’s a couple videos with exhaust but most sound bad on this car. I would like just a tad bit of sound
