Quicker Boosting Turbo than Stock?
Every aftermarket turbo I've seen seems to start making boost way later than the stock turbo...like 4000/4500 rpm or later. With all of my intake, exhaust, and fuel delivery mods, I'm getting a full 21psi from the stock turbo at 3000rpm.
I would think that with all of these ball-bearing/titanium/aluminum aftermarket units, someone would have a more refined turbo that spools just as quick or quicker than stock and still makes more boost. Why is that so rare? Educate me here because I've yet to see ONE that boosts quicker than stock.

Most, if not all, aftermarket turbos are geared to make more power. Making more power on a 2.0l engine means a bigger turbo which, in turn, means more lag. The only way you will get a faster spool is to go with a smaller turbo.
The advantages are faster spool but the downsides include: possible surge, no topend, increased intake air temps, etc.
I would say go with a stroker and the stock turbo and you will get full spool by 2k RPM.
BTW - the before mentioned problems will still be there.

You can find them everywhere but you have to spend a significant amount of money.
Just to give you an example, Subaru sells their VF turbo series which are designed for a specific variety of aplications, there are some turbos that they sell that actually spool faster than stock and also get better top end like the VF23 series.
For our cars there are other alternatives like titanium wheels(tme 6.5) AKA Tommi Makinnen rally version turbo. You can also find full ball bearing turbos for better spinning capacity. Also you have a huge variety of aftermarket parts that mate with the stock turbo could make your turbo spool insanely faster than stock.
The mods I am refereing to are: Full exhaust, better air filter, better bigger LICP and UICP, sometimes even the headers and off course a good BOV.
In addition to that you can always count on sending your stock turbo to get it ported and polished.
I explained many alternatives and solutions. If you try what I mentioned you will find out that the Evo turbo is simply amazing. I boost 30psi under 3500rpm on stock turbo(just for the record).
Some turbo manufacturers have variable turbo geometry that makes the turbo spool up superfast then the blades change pitch as the turbo spool faster to give you more top end/boost.
Rally cars and some tuners use an additional injector that feeds the turbo in order to create boost consistently and eliminate turbo lag but is proven to be superanoying because the explosions that it makes..

Just be happy that you hit full boost at 3000rpm. I don't hit full boost until 3600 or so in my driving gears. I assume you weren't talking about 5th/6th gear, since that's not a normal gear to make spoolup claims (tons of load in top gear), so you hitting ~21psi in 1st through 3rd gear is mighty impressive.

Anyone have a 3071 vs 16g dyno chart handy?

TME, has the titanium wheel (guts) lower weight of the rotating mass (compared to stock) and has a 10.5 hotside. OH WAIT! You are talking about an 05 correct? Isn't an 05 turbo the same as a TME Turbo? without the titanium internals? I guess the '03 I drive is now considered OLD SCHOOL?

Thank you Carlos! Excellent information. I do have all of the mods you mention to maximize the stock turbo performance. (see my registry link in signature)
I'm looking hard at the TME but a couple of things concern me. Is it not ball bearing? And are there surge issues with the TME 6.5? I see Buschur mentions surge issues with their "20G TME" model, and I can NOT have surge. I'm getting a little right now with my setup and I spend most of my time driving on very tight mountain roads with a lot of throttle modulation. This surge is driving me nuts. (I'm recirculating and all that)

Oh, and would the TME benefit from a port and polish much, or is it pretty much all set from the factory?
