Sorry but after watching your video I am afraid I have to mention that you are trying to promote the GBC line of turbos. I have to make clear that I am not a seller of turbochargers so I don't have any interest to promote one or the other. And now to the point. I don't think Garrett ever intended to substitute the GT2554/2560 with the GBC17/20/22 turbochargers. The ones are about to be discontinued are the GT2052/2056/2256 line of journal bearing turbos. However, not only the GT25s but also the GT20/22s are still on sale, seven months after these video was made! Also, there is not indication that the Td04s are going slowly out of the market - many cars currently in production are using Td04s and this family of turbochargers has been used in so many cars (of various brands) and are so strong (actually dominant) in the aftermarket that the idea that someone has abandoned them for me sounds ridiculous. Now about the results. Indeed, the GBC22 seems a better choice than the GT554, but even in that case I doubt if there is a 800rpm advantage in spool. About the Td04s, I presume that you talk about the one installed in the WRXs, the Td04L-13T. This is more comparable with the GBC20 which has a bit stronger turbine and smaller compressor than the Td04L-13T. The GBC20 maybe a bit stronger up in the rev range but the -13T would still be a better choice if we limit the boost at just 0,7 bar. The GBC22 is very similar in specs to the Td04HL-15T/16Ts, and I doubt if there is any significant advantage over them. And the comment about being an advantage of being oil-only cooled is peculiar. ok, if someone is not willing to change the stock radiator, it's the only choice, but, who does this?? At the end in my mind came the Greddy Turbokit of the first MX-5 which had the Td04H-15G, which is also very close in spec with the GBC22, and is still on sale. Also you choice for a fully forged engine....a GBC22??? Definitely not, the good old Disco Potato or some of its evolutions (GTXs/G25s) would be a much better choice for a fully rebuilt/forged engine.
I think it is hard to say anything about the GBC if you havent tested it. I actually called them and asked them about the GBC22-350 and how it performed on the forged engine miata. Apperantly their forged track miata pushed 330hp but not maxed out. I asked what it could have done if it was maxed out and they said that they think it could have pushed about 340hp. If that is true then there is nothing compared to this. I have been looking for a turbo that spools good and give me power around 350hp but there is nothing out there. So this is the best turbo you can find for that power. Since there arent many other people pushing this turbo on different octane someone have to be the guinea pig.
@@turnip5465 but ypu now are comparing a monster that can do over 400hp and cost like 3 times more. However i meant a turbo that you can buy with reasonable money and still get good performance in spool and in power. The efr is just too expensive
@@yosefrafael gotta pick and chose with the current roster, GTX2860R gen1/2 might fit the bill better or potentially a GT28RS with a bigger AR housing but you'd be pushing that thing to the limit to get 350 with a shit flowing head like the mx5 bp stuff
@@turnip5465 none of the turbos you meantioned above is any good for a small engine. i have a 1.5l turbo engine, the GTX2860R hits peak torque after 4600rpm the other turbos are even worse. Your missing the point with the GBC, it is made for smaller engines.
Thanks for the english video, sir! More of these, please!
Thanks for the english videos!!
How would the gbc22 turbo perform on a 1.4L engine??
How long would the turbo lag be?
For GBC do we need to put the restriction oil for it?

If I find and bring you a TD04, will you still make a full kit for me?
I love the stutter!
will be answered in the next english Q&A (16.01.2023)
is an oil restrictor needed on the GBC's? especially on a N/A motor that likely provides high oil pressure.
internally restricted i think
Hey SPS Team! Will there be a demo car available to test drive the GBC for NA/NB for prospective customers?

It's possible to remove the water cooling to a gt2560r? Or think a sistem to stop only in a trackday condition?
What turbo would you use on a ND track car if the priority is midrange power and quick throttle response, not peak hp?

How would a gbc20-300 be on a stock internal 1.6 na
will be answered in the next english Q&A (28.11.2022)
wie viel kostet ein gbc umbau bei nem 1.6 ungefähr?
