Is that a capsule on top?.

yes.
2 X SCE-200 (Clustered) --> SC400 Stage
HLV is 2 X SCE-200 (Clustered) --> SC200 Stage

HLV-HSP is 4 X SCE-200 (Clustered) --> SC400 Stage

Mr. S. Somnath, the director of VSSC has said that the Semi Cryo Engine is ready for trial.

Source : Upgraded Vikas engine will soon boost ISRO's rockets

Quote
Mr. Somanath said that, eventually, ISRO will phase out Vikas by replacing it first in Mk-III with a cleaner and safer semi-cryogenic engine. The semi-cryo engine is ready for trial; its stage has just been approved. "I cannot predict when it [the replacement] can happen," he said.

Hmm, I wonder if that means the SCE-200 will also replace the Vikas engine on PSLV.

With SCE-200 being a new engine, could ISRO have used 3D printing for any of its components? or Are they already doing it? Does anybody know?

When is the hotfire tests of the SCE-200 expected? Anybody has any inside info?

If the SCE-200 engine does replace the Vikas 2B engine on the PSLV second stage, it would take a very long time to modify the fuel and oxidizer tanks (as well as the plumbing needed to hook up the new engine) in order for them to store kerosene and liquid oxygen.

Great news. Hope ISRO does not make us wait another 6 months before doing the tests.

Test facility at LPSC is still 6-12 months away from completion. They might do the first few tests in Russia instead....

Hopefully we get to see the first test firings of this engine next year. A full decade of development at this point.

^^^Design looks very different compared to renders from recent years, are you sure that is SCE-200 and not some other engine?

It is very clearly RD-120 Family. The engine version that was used for Ukrainian fork of RD-120 Family development might be what is shown there. Also was a version developed in response to AJ-26 failure and larger version for LRB competition of SLS but since foreign made was not taken seriously by the US. Russian Space Web archives some versions well. The Russian successor fork of the former joint  Soviet RD-120 family is here however MoD RD-120K version is omitted: https://www.trade.glavkosmos.com/catalog/launch-vehicles/engines/liquid-fuel-rocket-engine/

SCE-200 is based on RD-810 not RD-120. Either way if it is SCE-200 in that video then we can expect ground tests to start next year.

https://yuzhnoye.com/en/technique/rocket-engines/steering/rd-810/
RD-120 was developed by Energomash working hip to hip with Yuzhnoye. After the RD-120K, Yuzhnoye designed their copy, he RD-870. Then an uprated single nozzle derivative, the RD-801. When trying to replace the RD-170 in the Zenith, they developed an uprated version of that, called the RD-810. And they sold those blueprints (but no method nor material formulas) to ISRO for the SCE-200. It is not clear if said development was paid by ISRO. What is known, is that RD-801/810 are mostly "theoretical" engines that were never built, much less tested and actually certified for operations.
A little tidbit: apparently the Chinese got hold of a few copies of the RD-120 (throu a Russian company), and that's what they based their YF-100/115 engine on.

RD-880 is their RD-180 derivative.
All of the Ukrainian derivatives of the original USSR/CIS joint engine families are listed on the left-hand side of the Yuzhnoye website section I linked. They are developed to the hardware stage and with the factors of the last decade are slowly testing them once the knowledge has been fine tuned  (EU replacement metallurgy programme and modernisation programme etc). They are developing and testing the direct copies then modernizing the design to 2st century standards and manufacture and then will market those versions. They are replacing all of their previous joint engines with their domestic counterparts. And developing upper stage replacements for those that were used on their previous joint projects whilst working towards developing their own proprietary green propellants to replace highly toxic ones and develop an improved Ukrainian RG-1/Sintin replacement similar to Russia's GHG emissions tweaked Naphtil (Naftil) and Sintin. Hydrolox, Metholox and other types are in the long term development plan.

There have been reports that Yuzhnoye Design Office in Ukraine has been destroyed. Yuzhnoye is the manufacturer of the 1st stage Antares tank, so if these reports are true, then Antares will never be able to launch again after NG-19.
