I was wondering y doesn't Lexus use turbo/SC? cuz i would luv to buy a Lexus equip with a turbo. if any chance i would want a turbo kit install i wouldnt want to void the warranty on my car.. lol wut u guys think?

 

bc they are pu**ies!!!

 

lol so ur not a fan of those huh? but i seen people modded their lexus with turbo/sc. even with the new models.

 

no.. i am a fan of them.. i was saying that about lexus.. lol
im guessing they are too worried about not being reliable with the use of those performance parts

 

Lexus engines are very efficient and even in non hybrid form, are ULEV II compliant.

Turbos also add complication and looking at lexus cars, from the interiors to wheels, they don't like complication much.

The new engines with DI are too high strung (compression) for a turbo to supply any true advantage.

Will they add some in the future? Who knows! Turbos are getting better and better as technology advances.

 

Mike, you're so PC.

You won't see a turbo with anything like big boost on an ISx50 for some time. The compression is too high and the internals are unique to work with direct injection, so low compression pistons to support boost are still a long way off.

You'd be way ahead just to buy the IS-F if you want bigger power.

 

I have to say, will Lexus have to answer, as they do have taken the Germans on so many fronts. Audi's S4 will go back to a V-6 TT.

Turbos simply attract enthusiasts.

What has happened as of late was the old American method, add bigger engines and displacement. That is what has happened to AMG/M/RS and now "F" with Lexus. "Lets slap a big V-8 (or now V-10) in a smaller car".

 

0o... so if it doesn't work with turbo than the supercharge might work right? since it only forcing more air into the chamber, and work with the high compression engine right?

 

reliability.....?

 

No, supercharging AND turbocharging are the same, forced induction. They force more air into the chamber so having high compression pistons (like ours) is a no no.

 

Note that there -is- a supercharger kit for the IS350, it only adds about 40 at the wheels though.

Why lexus does use forced induction I think is simply that it doesn't need to. Its engines are smooth, deliver good power for their displacement, and offer good fuel economy and low emissions.

Why complicate things and risk more warranty work when they don't need to?

 

^^^i agree reliability would go way down...turbos always = problems

boost leaks ect...they are a pain in the ***
fyi i had an audi a4...turbo was always confused on when to boost

 

I can think of about four or five reasons: Noise, reliability, power delivery characteristics, already have a V-8 model with 400 + HP in the pipeline and maybe just maybe blown engines aren't in the corporate image of how Toyota envisions Lexus.

 

I rather have a NA/ 400hp+ than a FI 400hp+ anyday period.

The unforgetable nightmare when my S4 turbo blew on the highway was just insane. The turbo reliability was the deciding factor which pulled me away from the BMW 335 coupe. I didnt want to go though the headache again knowing if I did purchase the 335, no doubt in my mind would I have added a chip and tear up that engine. Now I wouldnt mind if I had a FI weekend car hehe

 

get the new 1 series...i only noticed heating issues with the 335i...
