The only way I see out car being turboed is if some kind of STI style manifold is made and the turbo would sit around under where the intake box is. Other than that there is 0 room, I did a lot of measuring.

It's possible with custom fabrication. There IS room but it would take money. Plus the internals issue which would prob leave you if lucky tops 6-8 psi. So you'd have to do internals too. Also, you would have to do a custom tune to the ECU. 2JZ swap would be the only reasonable answer and a lot less money.

my friends at street image here in southern california have been making their own custom turbos, they have an agreement with toyota and they recent turbocharged a yaris, matrix, avalon, camry, (i dunno why) and one of the techs is making one for a is350.

5lbs is still boosting either way you have to have some sort of engine management or a tune. You can only use little lbs of boost because the engines internals aren't strong enough for a 15 -30 lb boost like a 2JZ could handle.

Ummmm. No. That would be the compression ratio is 11.8:1 not 8.5:1. There is no reason to believe the 2GR internals are not strong enough to handle more power.

i think he's just going off how 'legendary' the 2jz-gte internals were. i mean they could hold some serious hp.
i think about a month ago lobux or someone else posted some pics of the 2GR connecting rods and they looked pretty beefy, not like GTE ones but nice none the less.

And you can run 5 lbs of boost -without- any tuning or engine management. That's what the LMS supercharger did. It just used the large safety margin toyota/lexus built into the stock tune.
The complete lack of any aftermarket engine management -and- the high CR are both factors making boosting the 2IS a pretty pointless exercise right now.
The best, most cost efficient, way to make an IS250 faster is to trade it for an IS350. The best, most cost efficient way to make an IS350 faster is to trade it for an IS-F. And I'm not expecting that to change anytime soon.
The mazzuri headers, if you can handle not being legal, are about the only mod that seems to offer any appreciable bang for the buck on the 250 or 350, though you're still only talking a 10-20% power gain tops.
