It will make more than 400whp but octane will limit the capability. I agree with @Two Step Performance in evaluating your goals and go with the most responsive turbo that achieves that.
bear with me here.This is an easy one and lots of fun!
The 27WON Kuro will make ~420whp on 93 octane and ~470whp on an E30 blend

** Fueling upgrades would be required to use an E30 blend. It's a big step up in cost - https://www.twostepperformance.com/products/fuel-system-upgrade-for-2017-honda-civic-type-r-fk8
The 471 WHP pull shown above utilizes the quick spooling 27WON Kuro. The 529 WHP pull uses the slower spooling but higher top end producing RV6 R660. Both torque and WHP can be limited as desired during the custom tuning process.
Good question. To this point there is no flex fuel kit available that works with Hondata. They are releasing their own kit "soon". That is the ideal solution whenever they make it finally available. Until then you are forced to monitor your ethanol percentage another way, which can be done, but is more work. The flex fuel kit makes it easy and takes a lot of the guess work out of it.
The Kuro is another good option, more responsive and almost same HP. Bit more headroom on the MHI so depends on what you are using it for.
Apples to orange I'd say. Hondata is more simplified. Tuning companies and end users have the same Hondata software access. Hondata typically has more custom features than what you'd see from HPT. Of course what HPT offers varies widely depending on the application. And as I am sure you already know, they do not offer anything for this application.
For sure, just want to make sure if I get Hondata I won't be limited to what I can do for tuning the car for mods that require it.
A little smaller but more responsive with boost that comes in quicker. So depending on what you want or need. So solid option for some.
Yes you can run the car on normal pump gas. And it will be reliable. You don’t need a flex fuel kit if you are not using ethanol.
Hondata has the most features available of any tuning option for this platform at this time. We are still waiting on MOTEC support but the cost of that will not make sense for most. (estimated $8000 or more)
We have found the Kuro to be sized just right for the K20C1 owner that wants to maintain a quick spool but still have a lot of fun with their car. It has been our #1 selling turbo for the FL5/DE5 platform. The Kuro is not new to the market but it was a bit of a hidden gem until people started realizing that there is definitely such thing as too large of a turbo in some cases. I do think the MHI Stage 2 is another solid option but the cost can be hard to justify when compared to the Kuro, both having excellent reliability records.
