Honestly if your looking for more power, the best thing to do is to trade in your 250 for a 350 or an F

Your engine has a 12:1 compression ratio and very limited options for any sort of tuning.
Plus, it makes no financial sense as an IS350 is only about 4k more and adds 102 hp.... any forced induction kit costs more and adds considerably less power to a 250.
For example there's one guy in Greece (where they don't sell 350s) who adapted the IS350 LMS supercharger kit to his car- he added considerably less than 102 hp and spent considerably more than the difference between a 250 and a 350.
LMS doesn't sell their kit anymore, because even on a 350 it made little sense (about 6k for 40-50 hp).

I'm pretty sure Toyota ECUs are a nightmare to tune. Plus, you'd have to run meth to make any significant amount of power because of the high stock compression.
You want to do it, you'll have to build your own kit. Not worth it unless you absolutely must have a stick, and even then, you'll spend more money than you think by about 75%.

I'm gonna repost something i posted a while ago...
How to make IS250 faster:
1. Put car in "D"
2. Drive to Lexus dealership
3. Put car in "P"
4. Trade in Car for IS350/IS-F
5. Put IS350/IS-F in "D"
6. Drive
No seriously though, if your looking for something to turbo and make faster, you bought the wrong car. The ECU is untouchable and dropping a turbo in isn't gonna get you much power and will cost you more than trading up to a 350 for an extra 100+ hp boost.

You can argue that a piggy back ECU such as AEM Fuel Ignition controllers and GReddy EManage might work. But without having any access to the stock ECU, even the piggy back systems will be finicky at best.

From a financial aspect, trying to get power from the 2.5l doesn't make any sense. If you're made of money and dead set on doing it, you're still limited by the unhackable ECU that these cars come with. You could go stand alone, but then you would lose all the other features the OEM ECU controls.
If you really want a turbocharged engine in your IS250, I would advocate a 2jz-gte or 4g63 swap (I'm a mitsu guy, sry). Or try to shoehorn a domestic V8 in there (LSx swap anyone?).

Which don't exist last I knew... one member sent a stock one off to have a custom set made, but last I read hadn't gotten anything back and no response when trying to contact the company.
This ignores the other issues with the solution like lack of tuning, the unknown limitations of the cylinder walls, the limits of the fuel system, and the large $ in labor involved in basically rebuilding the motor.
Which will be hundreds of hours of labor (much of it in wiring) and you'll still have a dash light or two you can't get rid of at the end (and good luck with inspection if your state has em)... at which point, assuming you mean a 2JZ-GTE not GE, you'll be roughly as quick as a stock 350 would've been... granted you'll have much more potential to mod for more power going forward at least.
can you get a running car with either solution? Sure.
Does it make any sense, bang for buck wise, versus just ditching the 250 for an already-much-faster-from-factory IS? Nope.

MAPECU3 will work in open and closed loops for blown applications. It is my next goal but I'm out of funds for now. I have it setup and installed with this in mind so all the right wires and options are connected, I just need boost.........
