A peaky, laggy, centrifugal SC? I don't know, the 350Z engine does have a broad power band, and should be able to make up for the very narrow peak power band of a centrifugal SC.

Yes the is300 engine is very similar to the mkiv supra engine. I think the only difference is the is300 has variable valve timing while the Supra TT engine did not. I've heard of is300 with the Supra TT engine swap...now that's an M3 eater.

Powerdyne delivers substantial power increases over conventional centrifugal superchargers due to the unique Hyperdyne impeller. Featuring an exclusive curved-blade design that literally grabs air at low speeds, the Hyperdyne impeller generates low RPM boost levels that are unmatched by the competition. The airfoil shape and computer-matched scroll combination provides more pressure and flow at comparable RPMs than any other centrifugal supercharger on the market.

Meanwhile, a turbo that will outperform such an SC install will be much more expensive, require much more modification, require a little more maintence, will sometimes be less reliable and less drivable, and will normally require major changes in ECU, fuel delivery, and powertrain.
So, even if money is not an issue, the SC is normally a more reliable, drivable, and convenient upgrade. Depending on how you use the car, that extra horsepower isn't always worth the extra effort and trouble.

From what I have read, with the 2.5 liter engine and variable valve timing, the STI has gobs of power throughout the entire rev range, including low revs.

Isn't this where your everyday troll comes in and makes a comment about the 8's low-end? :D
If my speculations for a car next year weren't as frugal as I'm trying to make them - the 8 at $28k is as high as I see myself looking - the IS would be a serious contender...and should be with the competitors listed above in a $32-36k budget.
It'd be a close match in my mind - the G35s style and coupe nature (I imagine longer leg-room up front with the dimensions, and coupe fit, which I like) versus the slightly more comfortable nature of the Lex (resale value, service, reliability).

So, Supercharger, did you get banned over on those IS300 forums? Why else would you suddenly have all this spare time to come over here preaching to a choir of a different religion? :p

Gordon

I'm sure it's pretty fast either way

Ohhh and the USDM STi does not suffer from low end torque. It's able to spin all 4 tires with a clutch drop of 3500 rpms....that's some pretty good low end torque.

Supercharger just likes to provide us all with lots of info about various cars from time to time. He never comments or trolls. He never responds to comments (out of 247 posts I only see about 4 that respond to comments from others - I did a search). This is the 4th+ vehicle that he has posted huge amounts of stuff on. I cannot see any connection between them (the first was a modified RX-7 with a huge V8 dropped into it, others were VW Golf R32, Volvo S60-R, Chrylser Crossfire etc). Nobody know why he does this, or what car he has or want's to get (perhaps something with an SC).
