CTS Turbo F-series BMW N55 EWG BOSS Turbo Upgrade kit

Hey there, gearheads! Feast your eyes on the CTS Turbo F-series BMW N55 EWG BOSS Turbo Upgrade kit, a top-tier ball-bearing turbo setup with a stainless steel exhaust housing. This bad boy is crafted for the F3x BMW models packing the N55 EWG engine.

We didn't mess around with this one. Through cutting-edge transient flow analysis and stringent flow bench testing, we fine-tuned the turbine housing to house a GTX3582R turbo while keeping that stock fitment intact. And yeah, we're sticking with the stock location and your trusty stock wastegate—no shortcuts here, no sirree. This ain't just a bigger wheel slapped onto a stock turbo; this is a whole new game.

What's the real deal here? You won't need to send in a core or buy one separately. It's equipped with a dual ball-bearing GTX3582R-style Gen2 ceramic CHRA, a billet 10-blade compressor wheel, and a custom stainless steel turbine housing perfectly matched to this beast. Plus, we've balanced it to exceed OE standards, so you're in for a smooth ride.

This kit plays well with your existing factory installation hardware, just bring your own factory wastegate actuator—it's not included. Remember, you'll need to calibrate that actuator during installation to hit that sweet spot at 90% WDC max. And hey, make sure to have your big turbo software tuning ready via ECUTEK platform because this turbocharger is all about moving air efficiently at a max boost of 20psi.

For those in the know, this kit fits F30 BMW 335i & 335xi produced after 07/2013, as well as F32/F33/F36 BMW 435i & 435xi from 2013 onward. And a quick reminder: professional installation and tuning are non-negotiable here. Wastegate calibration with ISTA+ before tuning is a must to avoid any tuning hiccups.

Now, let's talk real-world results. Our buddy Jimmy over at TunedByJimmyB put this kit to the test on a 2015 BMW 435i GC with an automatic transmission. With a slew of mods including this turbo kit, N55 intake, high-flow cat downpipe, and fueling upgrades, they hit 491 whp and 484 ft/lb at 17psi on pump gas and 580 whp and 546 ft/lb at 20psi on flex fuel (55% ethanol content). Boost comes in gradually to prevent any rod-bending antics, so you're in for a reliable power boost.
