2022+ Honda Civic Base/Si & Acura Integra 1.5T / 2018+ Honda Accord 1.5T Turbocharger Upgrade – GIN Read reviews

Let's cut right to the chase, you want to know what sort of power the 27WON Gin turbo can put out, right? In the graph above, you see a direct comparison of the Gin drop-in turbo in Ball Bearing variety "green line" laid over the graph of the same car with the stock OEM IHI turbocharger"dotted grey line".

Well, how about 140WHP and over 130 WTQ over stock! The biggest difference you'll notice is that fat power band after ~3,250RPM when the boost hits strong and puts you back into your seat. Our best run of the day netted almost 330WHP and 324WTQ. Adding a tuner, bolt-ons, a custom tune, and ethanol brings a nice boost in power by themselves but Gin takes it to a whole new level. We didn't sacrifice too much spool down low by optimizing the compressor and turbine wheels and you can read more about how in our wheel selection section.

This data was collected on our 11th Gen Civic Si running a full suite of bolt-on modifications, some of which you can find here along with a E30 blend of ethanol. Once we add in our upcoming 27WON Turbo Inlet Pipe, we're confident we can extract even more power. We were so impressed after testing this turbo, we wanted to go run down some Type Rs on the streets of Vegas.

For 2026, we’re excited to introduce a brand-new feature in the form of Anti-Surge Technology on the Gin Ball Bearing Turbo. What is Anti-Surge and how does it benefit me?

If you look closely, you can see slots or grooves right inside the compressor cover of the turbocharger. These slots help direct air around the compressor wheel back into the inlet of the turbo maintaining smooth airflow for the turbocharger blades minimizing air separation. You can think of these as simple bypass ports helping to stabilize air pressure.

And here’s the benefit….you can get fast boost spool, better drivability at lower RPMs and better longevity on internal bearing components. Plus, if you ever heard a turbo near surge, it’s not a pleasant sound. With Anti-Surge technology you get a characteristic smooth turbocharger wind up sound that can’t be mistaken for anything less than outright performance. Drop a gear... and hear it for yourself! You also don’t have to worry about compatibility as no special fittings or parts are required to make this work with your existing components.

Gin is Japanese for Silver and is the name given to the latest versions of our drop-in turbochargers for the 1.5T engine found in your 2022+ Civic or Integra.

Every Gin turbo takes years of 27WON experience crafting upgraded turbos for the Civic platform and brings it all together through the careful use of upgraded materials, beefier internals, and latest technologies proven time and time again to deliver blazing performance on the street and on the track.

You could say we're partial to Ball Bearing (BB) CHRAs (center housing and rotating assembly). Now, there is a place in our catalogue for a standard journal-bearing (JB) upgraded performance turbo so we’re giving you the choice of choosing the right version based on your goals. In fact, your OEM IHI Honda turbo uses a Journal Bearing style turbo and it is a good cost-effective option to make more power.

So, here are the facts you need to know so you can make the right choice between Journal or Ball Bearing turbos. Do you have a budget goal in mind or are you after max power? The Journal Bearing Gin retails for a few hundred dollars less than its Ball Bearing (BB) counterpart. On the other hand, if cost is less of a consideration, the Ball Bearing option with the Gin is optimized for just a bit more power potential thanks to its compressor wheel configuration. So, expect peak power sooner and a 5-10WHP more of it at full blast.

Ok, what else? Let’s talk about what sort of driving you do. If you usually drive your car hard on the street or race it often then a BB turbo is the way to go. It will spool quicker thanks to less drag inside the Ball Bearing system. Also, a BB unit is able to take more sudden and abrupt loads better than its JB counterpart so response to throttle input is faster. When you are cruising in 6th then drop to 3rd to pull on that domestic or import trying to flex on you, the Ball Bearing turbo can take all you throw at it and then ask for more. If you’re not about that life and simply like to do some pulls here or there or prefer roll racing (in Mexico) then the Journal Bearing option may be just fine for you.

Below is a side-by-side comparison of the 27WON Gin turbocharger and the OEM Honda/Acura IHI unit found in your 1.5T Sedan or Hatch. Check out the breakdown of these measurements all meant to increase the potential power and responsiveness of this turbo.

• OEM compressor wheel inducer = 36.3mm
• OEM compressor wheel exducer = 47.7mm
• OEM turbine wheel inducer = 42mm
• OEM turbine wheel exducer = 34mm

• 27WON compressor wheel inducer = 47mm
• 27WON compressor wheel exducer = 58mm
• 27WON turbine wheel inducer = 46.5mm
• 27WON turbine wheel exducer = 41mm

These wheel sizes offer a great improvement in mid-range and top-end horsepower and torque without being too large and losing a lot of the responsiveness that the OEM turbo has. This turbo will be at home both on the street and excel in track, auto-xand even during the totally legal highway pulls you do from time to time.

100% brand new unit. No core exchange, no rebuilds, no downtime or waiting for machine work. The 27WON turbocharger utilizes high quality materials made from scratch for a unit that gives you that "new car smell."

On top of that, you'll get all the gaskets and fittings you need for a clean fresh install without having to run to the hardware store mid-wrenching. When we say it's truly "drop-in", we mean it!

• To fully take advantage of this performance turbocharger, an upgraded clutch and 27WON 4 BAR MAP sensors are recommended
• A tuning platform solution such as KTuner or Hondata are required
• Please read carefully if you are opting to purchase either one of the KTuner Basemap or Custom tunes to go along with your Gin turbocharger. After your purchase, you will receive redemption instruction on obtaining your selected map from Innovative MotorWorks.
