06 IS250 Modding Help And Suggestions
Alright so i have already ordered my joe z intake pipe then im thinking of ordering a tanabe exhaust invidia mid pipe and some headers . Will this put me over 200whp or about?? i change stock rims to rpf1's and removed anything uneccsory in the trunk and car . Also on the headers do they extended L shape bungs that go into stock place work ?? or will i still get a cel light ?? Also been doing tons of research and cant find anything about nitrous for the 250 only 350 i want to put between a 35-50 shot no more after the mods do the cars run lean ?? ive heard these are natural rich cars also will probaly put 1 step colder plugs just incase . Thanks to anyone for input and help new to the lexus scene

I have intake/midpipe/exhaust and I only got ~177whp when I dynoed my car (it probably wasnt very accurate, but the numbers wouldnt change drastically). I only did these mods for sound. You MIGHT hit 200whp only because of the headers.
Search "nitrous" and a few threads will pop up.

I have an 06 IS250 as well. Pretty much all the mods you can do are:
- intake (Joe Z/Fsport for performance, short rams for sound) - better throttle response
- exhaust (axle back depending on loudness and sound desired) - looks
- midpipe (depending on loudness and sound desired) - sound
- headers - some hp but won't really be noticeable i don't think
- suspension (coilovers or sports springs and shocks) - handling
- sway bars - handling
I feel the best mods for the is250 are the changes to the suspension to improve handling instead of trying to increase the hp. The intake and exhaust parts will give you better sound and some HPs as a bonus.

Being one of the most performance modded IS250's, i'll take a shot here...
Yeah, best scenario indeed, since the numbers dont necessary "stack". I dynoed at 187whp with PPE headers, Fujita intake, joez race exhaust before i installed my supercharger. I was told by the shop their dyno (dynojet w/ 4000lb rollers) reads ~12% lower due to the larger rollers. I would assume their 12% comes from their cars readings on different dynos, but they run 1000whp+ cars, so it's a 12% difference at that amount of power and I'd assume a smaller loss in shown power for my car. I took it with a grain of salt, as I'm not out to brag about a horsepower number i achieved on a car like this.
FWIW a friend dynoed his stock at i think ~183whp somewhere else... all depends on what dyno you run on/want to believe.
Mostly true, for me at least. Before boosting, i had a CEL from headers about 15-30% of the time. Seemed to come on when i drove very conservatively. I didnt much care though.
Overall, ~200whp is nearly achieved/achieved with all bolt ons. Nitrous can be run, my buddy has done that on his 250 with no problems. Just dont go crazy.

Mods Suggestion for Suspension
I have a question related to this thread, if I may. I just installed a set of Megan coilovers, the EZ's and I want some suggestions on sway bars and other related suspension components. While doing some research on bars, struts, sways (front and rear) there various combinations that can be used. From Ultra, Cusco, F-sport, Hotchkis etc. I noticed that there are chasis braces, top and lower from front and rear. Has anyone come up with a formula on which items and combinations used in suspension components and the pros and cons of their installs. I'm "Hella confused" on what to use as far as combinations.
I want better handling on windy highway roads but still have some sort of, so to speak luxury comforts, but I understand that comfort can be sacrificed. Can anyone give me some ideas? I'm itching for some MODS in this area.
