Green, 54 Green or AGT 52mm to replace my 71hta?
Probably something like that? There are a lot of variables when determining when the turbo will spool but there is about a 500rpm difference from the green to the red.
The setup you are looking at is pretty common with both the green and the red so I'd go hunt through the dyno results section and see if you can find a few examples of each to compare and make a decision from there.

Regardless of what it is we've got an engine that goes proud and reliably to 8000+ rpm. All the bolt on turbo's nose over but the red is still a perfect match for a fun street car 3800-8000. The green is still to small IMO on the 9.
You also have to respect the 400lb ft rule at low rpm's with the boost controller. You can exceed that with the green or red below 4000 so the earlier spool up of the green doesn't help that on a stock engine. Furthermore, Too small of a turbo/boost at low rpm can cause compressor surge because the engine can't ingest the air.
The green or red will still come up hard enough to powerslide the car or break differentials at low speeds. The red will just continue to pull over the green until redline.

Lots of good quality information here on turbo's. After re-reading this thread. I think I will focus on making my setup solid around my evo 9 turbo.
I have always been satisfied with stock turbo Evo's on a 300-350whp setup/tune. Straight line driving just doesn't get my adrenaline pumping as much
Once that is established, I can upgrade to a FP RED with some S2 cams. (if I really wanna notch up the power).

Great question. Alot of dyno charts are on AGT IG and FB pages.
Its not a bad product for the price, but no idea on reliability since its a fairly new turbo production.
Not much on these forums about AGT as well, tons of information on FP here tho.
Great question though, id like to see some responses and reviews of AGT turbo's

I just put a modified 9 turbo on by AGT. Everything looks good in the ~500 miles since tune.
I'd like to see durability of one that sees the track being that it's a low cost turbine housing I believe

I disagree. Its closer to 250-300rpm from green to red (MHI housing) on the 9.
