The sequel to the most successful and powerful drop-in turbo kit upgrade for the 10th generation Honda Civic is here.


The W2 turbocharger takes the proven performance of the W1 turbocharger system and brings it to another level. The W2 is capable of hitting power figures over 375+WHP and beyond. This is a turbo you can grow with. Whether it's bolted onto a stock block or a freshly built engine with beefed-up internals you can have the confidence that the W2 turbo kit will give you the performance you want and need.

After years of testing and pushing the W1 to it's limits this is the next level; the W2 is a 100% brand new-drop in unit. A larger center housing & rotating assembly (CHRA), a 9-blade turbine wheel, a beefed up housing & cover, and more are the key principles of this unit.

Dig into all the details below and learn what makes the W2 the new standard in CivicX Performance.

The architecture of the W2 turbo is all new. Designed from the ground up, the W2 is a true blank slate design. We took everything we learned from the W1 and applied to create a new turbo that truly does REDEFINE.

A larger CHRA, uniquely designed compressor cover, more robust turbine housing, and the capability of 400+ wheel horsepower make the drop-in W2 as unique as the owner.


At the heart of the W2 turbo is our custom Mitsubishi Heavy Industries (MHI) style center section. For this turbo we wanted quick spool characteristics despite larger housings and we wanted to increase durability. We did this by taking aspects of both a TD04 and TD05 style CHRA.

The W2 retains the same wheel dimensions as the W1 but is now fitted to a larger shaft and journal bearing system. This allows the W2 to take increased boost pressure and flow. Along with a larger water jacket and a larger full-face thrust bearing the W2 is ready to take on the power.

A 9-blade turbine wheel was chosen to help reduce rotational mass from that of an 11-blade unit. Clocking in at 61% larger than stock, this wheel allows for increased overall engine efficiency and is able to carry more power to redline. This specific blade count also helps keep back-pressure low in the housing compared to an 11-blade one.


An obvious goal of the W2 was to raise the horsepower and torque limits above what the W1 could make. The W2 can make more than +45 WHP and +25 FT-LB of torque over the already impressive gains from the W1. Peak torque is found around 4000-4500 rpm depending on tuning and the W2 carries both more power and TQ to redline.


Looking at just one example (the graph above) you can see that everywhere after ~3900 RPM the W2 makes the extra sauce over the W1. This turbo will be best suited for those running full bolt-ons. Even more power can be had with ethanol fueling and a built engine block.

Brand new studs, gaskets, nuts, and lines are included with every turbo so you won't have to run to the hardware store. Pair this with our Dozuki app for some mobile installation instructions and you’ll be calling yourself an expert turbo installer in no time.


Not recommended for CVT due to transmission torque limits
