judging by the fact that the top end rolloffs look to be the same, i think the top end cfm/psi is limited by the ECU in these two cases.
as a result there's probably more to be had up top if you relaxed the rolloff.
no 1st hand experience here, though... unfortunately!

I am putting in a deadbolt P/P TD04 along with an txs uppipe today. Deadbolt recommends a 250 mile break-in on the turbo. Will let you know how things develop. Keep your fingers crossed for a leak free installation.

I have had a deadbolt 'Monster' TD04 on my car since MAY03.
It has a port and polish and 'light clip'. IIRC, the clip was 7*and clipping is optional.
My car is an 02 with the equivelant of a stage 4+ level of mods, minus the STi injectors.
I'm running a stage 3 map, very lightly tweeked, max boost is 17psi.
It feels like a small NA V8 inder the hood.
Boost is early(I've seen boost by 1700rpm), and it pulls hard. MUCH better than the un-modded unit.
I like the performance very much, but....as I'm getting too used to it, I've ordered a 'Monster' TD05 from Jerry for even more power
If you want or need to keep the TD04 for some reason, get it Monstered.
If you want a better performing VFxx, get it ported.
It is worth the coin.
My 2¢

The butt dyno is great but I want to see dyno numbers on a car before and after the porting. I want to keep the TD04 because I think I'm wasting money on these other modds. You very quickly pass the price of an STi. I want only the least expensive and best power for the buck. I want dyno results.

I guess the BEST way to get your dyno numbers would be to have your car dyno'd and then install the P&P'd turbo, re-dyno it and see for yourself.
I seem to remember somebody getting 233awhp out of one on a lightly modded car, on pump gas and the stock IC.
It's not so much about more peak power, but a broader power band, increased driveability and lots less lag.

my understanding is that the ported turbo works just fine on an otherwise stock car. now, to get the best out of it, things like an up/down pipe, cat back, and ecu reflash would probably be helpful -- but again, not required.

The question is, if you already have those things and you add a ported turbo, how much do you gain? Does it flow more at 16 psi, and how much? How much sooner does it come on boost? With an up and dn pipe I have little to no turbo lag right now as it stands. I think $400 is very reasonable but want some hard numbers before I lay down hard earned cash.
