Turbo size confusion
OK, i've been reading lots of theory, and have had lots of people "tell" me stuff...and it's just gotten me more and more confused. So what i'm looking for is some specific facts.
Please post up the following if you would:
Turbo:
Engine:
Spool point (where you feel boost really kick in):
HP number: (If you've got it)
TQ number: (if you've got it)
Primarly interested in the top three peices of info. I honestly don't care about Hp or TQ numbers that much, i already know a turbo'd hatch back will kill just about anything weather i'm making 230 or 550 hp.
Thanks in advance, and please post only if your running a turbo'd setup....i'm tired of theory.

Turbo: 50 trim straight t3 .48 ar
Engine: d16z6
Spool point: full boost by 3800-3900 rpm
HP number: probably in the 200 whp range @ 10-11 psi
TQ number: probably in the 200 wtq range
i really like this choice of turbo quick spool and it pulls all the way to redline. plus the are a dime a dozen. and you can always up the wheel and comp. housing to with a 60 trim wheel if it isnt what your happy with

turbo: .48hot/.42cold straight up t3 off a saab
engine: b18b
spool point: full boost by 3800-3900
hp:
dont know how much hp im pulling but feels good enough to have as a daily driver...these turbos
can be found any many stock cars at the junk and most of these turbos are still reusable but the
only thing you have to do is actually go to the junk and rip them off...they're about 50-75 bucks...
but my setup is 550 injectors with .8bar externally wastegated...everything is fine...im planning to
upgrade to the hybrid turbos t3/t4 because they produce alot more power per pounds of boost.
But dont go to big or you'll get a bunch of lag unless you get those expensive dual ball bearing turbos..
which spool pretty fast for a big turbo...but a t3/t4 with a .60/.48 should give you a very nice pull and
a good amout of hp once you get ur setup tuned...

Very Old setup:
Turbo: Drag Gen III kit (t3/t4 .54trim /.63A/R
Engine: 2.0L 8.5:1 c/r LS
Exhaust: Drag cast manifold, full 3" turbo back exhuast
Spool point: 2500, 18psi by 4500rpm
Old setup:
Turbo: HX35 w/ partially cut down exhuast housing devider
Engine: 2.0L 8.5:1 c/r LS
Exhaust: SSACrap manifold, open 3" downpipe
Spool point: 3500, 12psi by 4500rpm
New setup....unknown stats
It should be noted also that the manifold and exhaust sizing/backpressure will play a part in how a turbo spools up.

manifold-ssauto crap(looking for new manifold now)
turbo- old one was a t3/t4 62-1 verry nice (new turbo is a t4 67/.68 w/p trim)
3" from frount to back
850cc injectors
gm 3 bar
@18 psi the car is verry fast but the seals are bad on the 62-1 so i wasnt able to get any #,s from it
will post numbers with new set up as soon as it is up and going

My old setup
Turbo-DSM T25 .48 .49
Engine- SOHC ZC
Manifold-STD+adapter plate
Spool point-2800comes on full boost 12psi at 3200
HP 200 flywheel [guess]
TQ- similar
Was great on the street instant power to race domestic torque monsters and went all right in a 2000lb 90 base model Hatch.
