Where did I say to add timing?

Deleted my comment. It's not worth arguing about. Just the one will do. Need an airflow channel.
Pictures of manifold, hotside, turbo mount/placement? There's a lot to be said about placement, hotside, etc. and turbo efficiency.
Most of the time I prefer to tune turbo setups to maximize NA power. That seems to be the best overall approach to building boost. Retarding timing will increase your exhaust temps but at the expense of making the engine feel underpowered. Its a completely different scenario on a trans brake so can't really use the same approach for a normal street driven application.

Hey Ed, she's bone stock on the manifolds.
Lol, been there done that. Embarrassing
Me too... "I'm fine, just go around... just go, go please, I DIDN'T HIT ANYTHING JUST GO, JESUS..."
edit: Dude that turbo's not much bigger than like Honda D16 stuff, you shouldn't be having spool issues.
I'm putting it back on the hoist tomorrow to have a look. I took measurements last time of preload, i'll dig that up to see if somethings moved. While I'm there i'll check if the wastegate is sealing.
I've got a 3582 that came off it and ran sweet. Bloody tempted to through it back on.
Yeah no kidding.Originally Posted by blindsquirrel
At what point should I disclose the turbo is a China clone
Shitty bushings and clearances? Not gonna lie my first thought was that, but you gave the PN and it said Garrett.
Yeah that thing should have no problem spooling.

Alright fella's, I think i'm getting somewhere now. Overlaid a log with my old genuine Garrett GT3582R. Nearly got it the same. Close enough anyway.
After pondering this in my sleep last night I think I've got to the root cause of my issue. I'm so used to driving a PD blown V8 that I expect full torque at 2000rpm. And in that car my normal driving rpm is 1500-3000. Going back to a 6cyl I need to realise it needs higher than that to meet my torque delivery expectations.
I'm going to unlock the converter and see if that makes me feel better.
I would think 3-4 psi from 2500 to the point the knock off catches up would be enough to feel.
Definitely noticeable. You'll have to educate me here, should I expect the 3584 to spool the same as my old turbo?
LOL Man I laughed hard at this! Carry on...At what point should I disclose the turbo is a China clone
That post exhausted my knowledge on the subject. I'm just a little fish on here. But since you didn't carry the 3582 any higher, was it out of steam when you stopped the pull?
Not out of steam but only just hangs on for the ride, duty cycle at 90%. Same boost on the new turbo duty cycle is 30%.
Ah hah! I'm not losing my mind. Boost vs. rpm is fine. Boost vs time is a WAY different story. Takes 2.5sec longer to hit my boost target. I can't get anymore timing into it. Cams are ball park. I shouldn't have put high comp pistons into this motor.
