If you live somewhere with ethanol you can run 15+ pounds of boost and get huge gains. Compression limitations are much less limiting with e85.

Any car can be supercharged or turbo-ed aka Forced Induction. Generally, the more air = the more power and stress to the internal components. Turbo has turbo lag as the exhaust has to flow, before the fins can spin and compress. Supercharger has no lag, but it directly drain the whole engine off the power 10-15% of it.

I honestly think, if you want a mods friendly vehicle, you are on the wrong one. Lexus are for luxury, social symbols/status (FE, Lexus IS250 vs STI,and people think your Lexus is more Expensive, always.) Others AWD performance would be VW GTI, Golf R, Subaru STI/WRX, and Mitsubishi Evo. Those are aftermarket friendly, as many people knows how to work on them, parts are readily available anywhere, cheap. Still, going to mod your vehicle = tons of money wasted.

Here are my ultimate questions, why do you want more power ?

Do you just want to meet people at car meet, coffee and car, and brag about how you can poor your money on the car for more power on the Dyno, and never actually race ?

Do you race ? Do you auto cross ?

What will you gain from having more power ?

Would this work on IS'? An Lotus Evora S Supercharger. I believe it is a same engine derived from camry v6 that uses Eaton supercharger.

You know, I hate posts like this because they offer basically nothing of value to the community or to the OP that asked the questions.

Why do you care if someone want's to turbocharge their IS?

I like my IS quite a bit, but I'd like it a lot more if it packed another 60 horsepower or so.

Your opinions about wasted money and what a Lexus is for are both irrelevant and uninteresting to me. I could give half a crap about what you think about the mods I choose to put into my Lexus.

However, when you come on forums and spout that crap it further deters aftermarket support from ever really developing because companies see a community that says "why would you want to do XX" as opposed to "hey, I can't wait until I can do XX". Would you create a product for a market that does that?

So what will I gain from having more power? More bloody power, that's what. It'll make a car I currently enjoy into a car I *really* enjoy. Why would I want to look at BMW/Audi/Mercedes/Infinity (all of which offer more performance than the IS) if I have a solution for my IS to give it more power?

Trade it in on a used IS-F.

But it is true that, within reason, there isn't much that can be done, especially compared to turbocharged cars, which not only start-out with more torque, but are easily modded to allow more boost and thus power.

Whitigir

@a790 : it is your car, and money, do what you want with it. @dizlex: thank you... It is the fact if some one want to have a modified car, it would always be easier to purchase a car with big after market support. Such as Evo, STI....smaller market support = you can't find part when it break! or it would be 3-4x more expensive to work on. Again, somebody need to start out the trend. A790 may be that person, go turbo charge your car....develop kits...support the platform. Remember to make a progression thread.

I'm liking this thread. Considering doing a custom SC on my 2014 IS 350 but not for power. More for aesthetics and the BOV sound.

You will always have people like the person up above that asks WHY DO YOU NEED TO MOD IT!!

Um...because i want to, and I have the money to do so. Plain and simple.

To be honest, boosting this car (the IS) is going to be a wasted effort to be entirely honest. Since the ECU is locked by Toyota, unless you swap to an aftermarket ECU, you will never be able to get any gains from it. You MUST tune the car in order to gain anything.

Thus, anything that Lexus builds, you will not be able to really mod beyond the basic boltons, which again, will be nullified once the ECU recalibrates the fuel trims.

To the person that said "get an IS-F", you will end up in the same situation again. An untunable car, thus after basic boltons, you're screwed.

OP, you can mod it, but don't expect earth shattering changes. If I could recommend, buy another car and begin to make something out if it.

shirosan

I really respect your input and opinion; however, it is a little unnecessary but thank you for educating me...and SARD Racing does have access to the maps straight from the Toyota Motor Corp. Of course you'd have to pay for the premiums but it's available. Hope you have a great day.

Lolololol this is great.

I know this is an older thread, but I thought we should update it.

We can tune the 3IS, and we have just released our 3IS Supercharger Kit, with Stage 1 rated at 366whp (about 430 crank hp), fully tuned and reliable:

I am also liking this thread. I am also of the belief that if you want to add power you can and there are finally some real solutions out there,

leg3ndary

I don't know about this assessment anymore. The guys at RR-Racing are working on some compelling projects, which includes an ECU re-flash and a supercharger kit. Video is posted a couple of posts above, I recommend you check it out and follow their build thread.
