Should I try G25-660 next? I'm really instrested about the spool time with the 0.49 AR housing. Almost 60 lbs/min flow with so small AR, what sorcery is this....
If you were in the US I would get you a good deal on a G25-650. If you want to cheap out a bit and not get a Garrett, you can get a Pulsar G25-650. I am not sure if they have the t2 housing though. I am also about 90% sure it is a "re-worked" Chinese copy.

They're available in T25 .72 housings with internal gates.

I'm waiting on my Pulsar 2860 turbo to come back after a compressor wheel change and VSR balancing. Maybe ready this weekend, see my build

Yeah this one looks intresting. Looks like a real Garrett G25 but ~2.5x cheaper https://www.pulsarturbo.com/product/...bearing-turbo/

My local dynoservice is a Pulsar reseller

It isn't a real Garrett just so you know. They are all made by Booshiwheel and then have "inconel" wheels added. Below is a decent video of one of the Boshiwheels being tested. Now saying all that, when I get some spare money I will be picking up a G25-550 Pulsar turbo to check against my legit Garrett G25-550. Along with one of their GTX t2 turbo's to compare against my legit Garret ones.

Unfortunately not. I have not had time in the past 6 months to actually work on my car any. Was planning a quick DBW and EPS swap back in January. Car is still sitting. People keep buying turbo setups, and I can never get far enough ahead to work on personal projects.
