question about garrett gt3076r

[gsx tuningart]

what is the difference frome this:

and stock gt3076r with 0.63 A/R turbine housing?

This is a great question for @JusMX141

I think the answer would be that a "stock" gt3076 would come with the t3 exhaust housing (0.63 a/r) which is a little larger than the bolt-on ( around 46-55 a/r??). So, you would need a manifold with a t3 flange and the 0.63 housing may create more power but have more turbo lag. Hope that helps.

Most likely better spool but less top end on the bolt on gt3076. I have ran a gt10 version of the bolt on gt3076 which is smaller on compressor and turbine and flowed 45lb/min at 26 psi, full boost at 3800 rpm.

what could I expect with stock gt3076r .63a/r and my configuration?
i mean range of spool and rpm.
i running with normal fuel 100(Ron).

GT11 is a GT3076RL CHRA which was produced before the current 6-blade model when Garrett offered different compressors for the 30R series and even a few different turbines. The turbo in the link has a 55/76mm compressor and a 56.5/53.5mm turbine where most out-of-the-box 3076R's will be 57/76mm and 60/55mm. It will spool quicker but mass airflow will likely be a little lower from the turbine restriction. I tried to describe that to the best of my ability in the listing without doing a side-by-side comparison.

Thanks for your answer.
Ok, this is clear.
What I would like to understand is that spool range will have and how much it will push after.
Can I see the spool of 26/27 psi around 4000rpm with stock gt3076r .63A/R turbine housing?
After that, how many rpm will stop pushing?
Maybe is a stupid question, but i'm new about turbo experience.Running for 10 years with just big 16g.

best i can do is a couple videos of a datalog replay of a gt3076r with a .63 turbine on a 2.0L honda. the only reason the boost is going up so slow is because i had boost by gear enabled to try and keep from loosing traction when the boost hit. without it, the would break loose till 4th gear. the turbo spools hella fast. e

There is no way to guess this information with any form of accuracy being that every car, every build, and every tune are different. Turbine trim of the 56.5/53.5mm 30R wheel is 90 so it's definitely not aimed at being a good spooler for it's size but will flow a ton of air while retaining fairly-quick recovery.

ok ,i understand that my question ,can't have the answer.
I'm scared ,because i don't have a idea how this turbo is.
Anyway,thanks for your answer!
