my gt32 doesnt fall off up top! the turbo has a gt3251e CHRA, with custom precision housings. IMO the turbo is like a 57trim out put wise, while spooling like a 50trim(all refering to t3/t4, .63AR)
and WTF do you mean buy 57trim. you need to be WAY more specific about those things. There are thousands of differant 57trim turbos on the planet.

assuming i get my POS together and down to the cities to get tuned....

he means a t3/t4 57 trim... the "tufte turbo". Even I knew that.

I am just saying what i said. my dad gets some people every once and while that come in asking for a 50 or 57trim. my dad knows what they are. but is always like which one, there is thousands and gets the dumbest look on the kids faces.

lol, you confuse me faber, if you didn't mean it, why did you say it, and go into detail?ahahahahah, have you ever met faber? and did you really have to ask?:D

like faber said, trim is nothing more than (ind^2/exd^2)*100
57trim is just a common name given to a popular T04E compressor
My gt42 has a 53 trim compressor and 84 trim turbine....
if you have the trim # and either ind or exd it is easy to find the other

well, fabers turbo(AMS GT32) is roughly equivalent to a garrett 50 trim, .60 a/r. Which is smaller in size and probably less efficient (AMS wont give out the exact specs) than a GT3076R, .82 a/r. Faber has no problems up top, I dont think I will have to worry about that. There is a guy on ka-t.org that is making 417whp with a similar setup to mine @ 19psi with a gt3076r .82 a/r.now see i'm running the same turbo same specs, i got the atp 3" v-band.
now with my motor i should see full boost buy say 4800ish give or take based on my monster manifold. now i rev to 9k so i will have a power band.
but unlike you i will not make near the torque you will, so all i'm saying is that you need to look at the fact that it will just make it harder fo ryou to drive the car to it's potential. but i spose we will see next year.

gt3076r, 18 lbs , high 200's for torque.
now this is with a small .48 turbine

on the KA, you will see ~400whp @ roughly 19-20psi, hitting full boost by roughly 5k-6k rpms(dont quote me on that....) depending on setup. That should net you depending on tuning, about 350ft-lbs of torque.
this would be the gt3076r with the .82 a/r turbinehere is a dyno from some guy down in georgia that has a similar setup to mine....

Ivan has 40psi on his gt42 sooner then 6k.
you should have around 20psi at like 4k.

eh maybe...like i said not too sure about that...i thought it would be about 4200-4400 from when i did all the calculations from the compressor map, but i wasnt sure if i figured right.
-
ball bearing doesn't mean faster spool...... you should know that faber...haha
-
well in a round about way it does....it takes less force to spin a DBB cartridge than it does to spin a ceramic journal bearing cartridge...which means the turbo wheel will reach higher speeds faster...which means the compressor will flow more air faster = boost faster.
-
Yes, i know this. DBB makes the turbo more efficient, also get more devoted lubrication and coolin. and then what nate said.
I would be hard, but if you have 2 identical turbos one with journal bearing and the other with the DBB, 95% of the time the DBB will spool faster then JB turbo,
WITH ALL THINGS BEING EQUAL
