Bigger turbo for type r ?

I've used Hondata on my previous 2018 SI and it was fine regarding the basemaps, etc.

When I got my Type R, I went with KTuner v1.2 because at the time I made my purchase, I wanted to have a wireless OBD II module (vs. the plug in for Hondata), and I wanted to be able to stream to my headunit (I have a 2018 Type R and I couldn't get Hondata to work on my 2018 SI head unit). I also liked that at the time Ktuner had multiple power options by drive mode (not sure if Hondata also does this today).There was also a KTuner unlocker within a 2 hour drive of me (versus having to ship out to Hondata).

Also @KTuner customer support is top notch. James responds very quickly to any questions I have. Also the best tuner for the 10th gen civics (shout to @D-RobIMW) helped develop the KTuner basemaps and is not far from where I live so it was a no brainer.

If you're going to get a custom tune, find the most reputable tuner near you and see what he/she prefers. Go with that.

for me it was just as easy because @Hondata is a 20minute drive from me so turn around was super quick. Luckily SoCal has so many extremely experienced people who are also O.Gs in the Honda game
It really all is preference, whichever you feel more comfortable with or had most experience with.

That is done via tuning. Unless this turbo is larger and laggyier making tq later which will make the car slower.

It’s a known fact these cannot support the fuel needed past around 400whp so why buy a kit that isn’t needed. It’s a waste of money is what I’m saying. If the stock turbo can max out the fueling why upgrade?

I agree with your statement that the full race kit is a waste of money until fueling is fixed. If you look at their dyno graphs, their baseline is 317whp. and final numbers are 396 whp. First off, this baseline is way high, but let's forget that for a second. This is a delta of 79 whp.

On the dyno we tuned my car, completely stock FK8s were around 295-305 whp. We ended up at 376 whp. That is a 71whp gain, for ALOT less than the full-race set up. Granted I do have full bolt ons, but honestly my Remus exhaust is not really adding that much power. It is the downpipe and maybe the intake doing most of the heavy lifting. A custom tune + downpipe + intake + KTuner would be a much better and cost effective solution.

I never said to buy it. I just said it moves the curve to the right.

Could it be because the exhaust isnt a true straight pipe? like too many resonators?
That's why I like the Injen exhaust, it is a true straight pipe with no resonators at all so better for a free and high flow system

I wasn’t directing all that at you but the 2-3 people who said explain why this kit isn’t needed or tuning questions

Plain and simple you can’t get enough fuel for the stock turbo so upgrading it is like throwing money away until more fuel is added.

What I meant to say is that with a custom tune, my Remus exhaust will give you the same power upgrade vs other much cheaper exhaust options. I’m trying to say you don’t need to spend $2500-$3000 for an exhaust when a $1000 exhaust does the same thing, or even removing of stock mufflers does the same thing power wise.

Also, the Remus is essentiallt a straight piped exhaust when you have the valve 100% open.

Upgrading a Turbo can be more about "efficiency" than simply adding more power. An upgraded turbo can turn down having to run higher PSI to obtain the same result. Lower heat signature, better flow, and less stress on the entire system.

This. I'm not an expert, but I'm guessing that anybody getting near 400WHP on the stock turbo is way past the efficient range of the turbo. You can tell by the way the torque and boost falls through the rev range even on FBO tuned cars, that the turbo is near its limit.

The stock turbo would be further to the right out of its efficiency mapping and running much hotter. With a stock set-up and maximizing the available fuel, the heat signature would be so great that the ECU would pull timing to save the motor. You never tune a stock fueling system to its MAX - the only time that it is done is to show a #, then it is dialed down. The closer a fuel system gets to maximum, the more spikes in the power curve (which is not good for the cylinder's sake). This can be alleviated with an Auxiliary Fuel System or Flex Fuel System - but yes, the turbo does have a limitation.

So first rebuttal, ktuners support staff? Dicks, their site is pretty unuser friendly luckily I had a dealer near me, I got 2 huge a-hole emails from them, w/e though, their tunes legit, I slammed a prl intercooler, down and cross pipe, strait to my hks legamax exhaust, Tokeda (afe) intake, I dunno after all that stuff I’ve not dyno’d it, but it’ll toast most corvettes, they just roll up to the next light down their road cussing and shaking their heads. Don’t know what more you could really want outta a 4 door Honda, I put the back seat half down and put my husky and German Shepherd in and can still put my kids car seat, nobody around even wants any anymore get that stuff before you go exploring other ground you’ll be impressed

A bigger turbo would help with higher horse power for the reason that the torque peak will hit at higher rpm and more hp

You can get to 375-385 whp (up from baseline of 305) and daily drive with simple bolt ons and custom tune (see my signature). The main bottlenecks are MAF voltage and fueling. Turbo has more room above 400whp.

Also, The extra 20whp or 5% whp not gonna give you a noticble change in driving experience.

My car is a daily. Runs great.

How linear is the power with your FBO custom tune? I would love more power, but I'm hesitant to get it at the cost of unbalancing the car.

Is it really worth it though? My car is basically FBO right now making about 350ish and it's enough.

With the bigger turbo, isn't there also a larger chance of having lag?

I see your point but the bigger turbo option just doesn't seem worth it to me when the car is already this much fun.

Spool is only affected from a stop. Once rolling you are past that RPM anyway. Less boost, with the same air flow and a lot cooler - thus, a consistent and efficient power band.
I impose it on no one, just food for thought is all.
It is more of a track/Race set-up, daily can just remain stock, but when it’s hot outside it won’t be as efficient.
