Obviously those tiny turbos were screaming to ~19-20 and back down to 17-18psi !!!!!

Here are a couple posts about the T51 from other members who have or have had this turbo on their cars.

The car will not be streetable
The car wont be fun to drive in traffic
I suggest this turbo to only drag racers

The car is still streetable but it's not fast off the line unless you slip the clutch and get the RPM up there. For the boost pattern.
2k rpm: 0
3k rpm: 5 psi
4k rpm: 9 psi
5k rpm: 13 psi
above 5k: full boost in no time.
I have run 27 psi with the T51R kai turbo. When it's above 5k rpm, it will go to pretty much to any boost you want in less than a sec. My engine is mild street ported so it might spool up the turbo faster than a regular stock port motor.

However, the guy I bought the turbo from showed me a video of this turbo on an RX3 drag car. This was a seriously ported and built motor, but nonetheless the boost patter was more like this.2k rpm: 5 psi
3k rpm: full boost in no time.
But also, I know the T51 is capable of much higher boost levels. The Garrett units efficiency drops off after about 22-24 psi. Hope this helps.

GotBoostd7: thanks for the quotes and RPM/PSI estimates. By chance would anyone have RPM/PSI estimates for a T04R. And anyone know about the streetability on that turbo. Ball Bearing if ya have the info.

Thanks for your input GotBoostd7! Yeah, that GT3540 setup seems pretty nice. I plan on having an aggressive street port and I don't plan to run any more than 24 psi, even on race gas. Thanks for all your help! I think I shall go with the GT3540. I guess I'll use the HKS GT wastegate 60mm too. Now it's just time to find a manifold and downpipe maker....

yup, thats the same turbo we have on the talon.
I maxed that thing out at 570 WHP on the Talon
IMHO its a wee bit small for a rotary, and that compressor is a 55lb/hr wheel
maxing out a turbo is rare, we got it to go to 11hp per lb, 10hp/lb is normally the max
But an awesome turbo nonetheless. It will be torquey as hell. And very fast boost response. On a rotary you want to go bigger compressor cause of the lower BSFC. I'm not sure if it can make the same power on a rotary, they like bigger exhaust housings.
