Well, that's your opinion.
Some would argue that a person that buys a car with an automatic transmission isn't interested in performance. And some would also argue that the aftermarket parts manufacturers are interested in making as much profit as possible (there's a novel idea...), and would hit the markets that offer more possible customers. In other words, the relevant models that sell more units.

performance 250 in a car weighing close to 4000lbs is kind of an oxymoron.
i have an old toyota minivan with a manual tranny, it was never intended to be "performance" anything even though it has a "performance" tranny, and I will never try to make it into something it isn't

As far as the headers, I cannot answer with 100% certainty, but if I were to guess, I'd say it could be clearance issues on the 350. I'm assuming the 250 has more space under the hood thana 350 does which would make it a lot easier to fabricate headers for a 250 versus a 350 where it may take some more R&D to make a properly fitting set.

I think most parts will work with both cars. However I doubt that either car will get 30HP out of all the bolt ons.... let alone make up a 100HP difference. The major performance mods will be for the 350... if any come out.
Why? Why would someone pay $5K for a supercharger that gives 60HP.... when they could have got a 100HP upgrade from the factory for $4000? And they could have had lexus reliabilty and better brakes.
Manufacturers will sell parts for people who will buy them. That is a lot different then selling parts for cars which have the most owners. It doesnt matter that the 250 outnumbers the IS350, by 3.5:1. If only 10% of the 250 owners want more performance.

I though about replacing rods/pistons/injectors on my IS250 with Wiseco's 9.1 and Cunningham rods, making custom exh manifolds and adapting twin Garret GT2871R's
I paid 29K for my 250 and spending an extra 10K on a supercharger or turbo kit will blow any IS350 of the water in terms of bang for the buck dilema.
I'm not knocking the 350 but why pay almost 46K for a fully loaded 350 and then another 10k for FI, when the 250 can probably do the same with less $$ and a built motor...

There is just too much to worry about. Why not just buy the 350 to start and call it a day. How will you drive with your car down for months? Who is doing the install? Are they reliable? Will the Manifolds crack? Will you pass emmissions? Can you drive by a cop without being pulled over? And what about brakes? The 350 has 4 pot brakes to start. How much more will 4 piston brakes cost you?
If your car dies, who will fix it? And how much will it cost.
I am not trying to sound harsh, but most people dont have the desire or the patience to invest in mods like this.

Ok i'll chime in.
1. Get a full cat back exhaust. (Either custome (customm built or LMS SS exhaust)
2. You have two choices. Get the Joe-Z Intake Pipe with Drop in Filter (blitz or K&N) which is closest to a CAI as it gets. OR the 2nd choice, get the k&N typhoon intake--which at least has some type of heat shield and is fully integrated with the stock intake scoope. You might get some heat soak, but it wont be as bad.
3. Get the megan Headers.
4. Get light wheight Volks Wheels (size is your option.)
5. Pull out your back seats // loose some weight
6. Extreme ? Get a superCharger?
7 --> now add up the cost
Dual Catback = $1200
Intake = Joe-Z $119+$55 for Drop in Filter / Typhoone $200+
Megan Headers / = $500 +
Volks Rims / = $2000 + Tires
SuperCharger / =$4000

The vast majority of people who want performance will go with the 350. Aftermarket companies know this so they will focus on what makes them the most money, which is making performance parts fro the IS350. Stuff that is easily interchangable like exhaust will be available on both models, most other things will not. Sorry, but that is just the way it is. There are a few vehicles where the lower model has more performance parts (M35 vs M45) for example, but the IS is not one of those.

For me, the 250 made more sense. I prefer to have a manual transmission. I'm not knocking the 350. The engine is awesome, but the auto part of it sucks. Yes, many have said that the auto is a fine piece itself, but for me, I would get bored quickly. Trust me, I am driving a paddle shifted Mini Cooper S, similar setup to the 350's. The handling is cool, the shifting is boring. So for all of you that say 100hp more on the 350 for only 4k, I say if you can get past the "auto" part, by all means get it. Not for me. I want to be in control of the car, not some piece of technology.
So on that note, 250 will benefit from any forced induction, cams, headers, etc stuff that they can develop. Its not fair to say the 250 should be left out because the 350 has more performance potential. We just need more serious Lexus tuners to come to the scene. BMW has no problem in that respect. Many aftermarket performance parts are available for 325 as well as the more touted 330, and soon the 335. None of that stuff about leaving a particular model/engine out or the notion of luxury car buyers are not interested in performance, so on so forth.

who said there is no space to tune 2GR/4GR engines?
I strongly suggest you to read this article of a guy made a conversion and 4L twin turbo out of 2GR.
