## Description

We kept hearing about how great the s366sxe was... but with it being a standard rotation t4 turbo, it can be a little expensive to install on these trucks because it requires a "t4 kit". We wanted to see how a reverse rotation, drop in, 366sxe turbo would perform in our dual ball bearing KC38r turbo frame... 1 year later the KC38r 366 was born and the results are AMAZING! It spools faster, runs cooler, and makes more power. All testers reported how much cooler and cleaner their trucks run with the updated version. Some reported a 200 degree drop in EGTs. The power comes on so much stronger and quicker with this new turbo, which makes towing and daily driving so much better. Although the turbo still has a 66mm compressor wheel, it is drastically different. It is a larger, 7x7 wheel and is modeled after the 366sxe compressor wheel... same profile, shape, and blade style, except it is reverse rotation. This wheel is not only bigger, but stronger. It has thicker blades, thicker hub, and thicker backing, this makes it much less prone to fatigue and wheel burst. The turbine wheel is much larger, 73mm vs the old 70mm. It is also a much taller wheel with larger blades. It does not just share the same "dimensions" of the sxe wheels. It is the same shape, size, thickness, and blade profile as the s366sxe turbine wheel. Please see the pics below to fully understand how much different the new wheel is. (even though the turbine wheel is much larger, it still spools much faster. It is crazy what modern turbo technology can do to a 20 year old turbo design). Most people focus too much on the "compressor wheel" because that is what everyone can see, but the fact of the matter is 90% of the "turbo magic" comes from the turbine side of the turbo, and we did our due diligence to make this the best option on the market. We also increased the thickness of the shaft to support the extra power and help make our turbos even more robust.

## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    The best replacement
  

*by E***C on Reviewed in the United States on November 14, 2019*

If you need more power or a replacement or just looking to lower your egts. This will do it all. Works well with factory injectors all the way to hybrids. Without any tunes a stock will push around 10psi drop this in with stock setup your pushing 25psi and with a low moderate tune your already at 30psi of boost. Egts do lower and uses a ball bearing setup opposed to connical bearing in the OEM turbo. And this one to include the bearings are fully rebuildable. Awesome product

    Great drop in turbo
  

*by B***. on Reviewed in the United States on July 27, 2019*

Put this in my 01 along with 180/30 injectors and a big improvement over just having my hydra with stock injectors and stock turbo they should’ve ran like this from the factory!!

Love this turbo! Easy install dropped right in works amazing with my stock injectors and zf6! Spools up when towing little laggy in 5th gear but not bad! Sounds amazing spools up to 36psi with basic tuning
