W2 Drop-in Turbo Upgrade - Design Pt 1; Our Goals

A few weeks ago we announced some exciting news was coming for the Honda Civic and Civic SI. Today we officially announce it. I’m assuming many of you clever folks have already guessed it from the teaser image in our last blog. but anyways, let’s make it official right now. ;)

27WON is ecstatic to share our upcoming W2 turbocharger kit for the 2016+ Honda Civic with the 1.5L. The W1 drop-in turbocharger is going to have a big brother in the form of the appropriately named W2.

Before we go deep into the specs of the W2 turbocharger kit we want to do what we do with all of our products and share with you our goals for this turbocharger upgrade.

First and foremost the W2 needs to out-perform the W1 turbo kit in both horsepower and torque. Second, it must be a 100% new unit. Third, it will be a drop-in turbo upgrade. Our kits are made ready to install out of the box with OEM and most aftermarket parts. We don’t believe in requiring you to run only 27WON parts in order for you to enjoy this upgrade. You will find this unit performs its best with supporting 27WON modifications like our front mount intercooler and turbo inlet pipe but you don’t have to add those parts or even have them to upgrade to the W2.

In order to make these goals a reality, we had to consider several aspects. Getting it to fit into the engine bay was single-handedly going to be the most challenging part. There is only so much room in the car to fit a larger turbocharger and we needed to identify how big we could go. How much further could we push the stock turbocharger envelope? Could we push the stock frame further or would it cause compromise on other things? We feel we came up with a great solution to this problem that will share with you in our next blog.

With supporting mods and tuning the W1 is capable of netting on average an additional 40+whp and +15 feet pound of torque on 91 octane fuel. With the addition of ethanol-blended fuel and more boost, we can generally see those results double. A 80whp bump in power is great gains for a drop in turbo kit (results may vary). We understand that for many people making the switch to ethanol is just not in the cards. This is mostly due to the limited availability of the fuel (most don’t want to drive 50 miles just to fill up). For this reason, another goal we had was to get even more from pump gas. We intend to make more power with less boost. This ensures we can cover a broader range of power bands and still keep it safe for a stock bottom end.

Let’s recap what the W2 will do. It’ll be a drop-in, 100% new - no core needed, it’ll deliver more power and torque, and it’ll allow people that don’t want to run exotic fuels to get more from pump gas. 

With our goals identified, we moved forward to the next steps. We design, create, & test. And as always, will be sharing this journey and results with you along the way. We are super excited to create the next level of performance for the 10th generation Honda Civic and hope you are too.

REDEFINE the Aftermarket.
