This is the step up you want.
Install was a little tricky. Had to do some modification to make it work. The results are amazing though!

Love it
Start off by saying I bought this turbo when the housing on my stock one cracked. The turbo kit is awesome. It installs easy and all the parts were there. The only gripe I had was it didn’t include new coolant line gaskets. They are one time use and you HAVE to replace them or they will leak. I had a lift available so the install went smoothly. I think it could be done with one person but it makes it a ton easier to have a buddy at the top helping. The car sounds a full octave lower at the exhaust note and the lag difference isn’t that noticeable. I roll race the car so I just make sure I’m in boost and don’t have to worry about it. Highly recommend.

Quality control!
Only had a small issue with the kit. But if it hadnt been caught and corrected i couldve killed my engine. There was loctite or something clogging the barb for boost line. Other than that 5 star product im lovin it so far. Just please work on quality control.

Solid Turbo but had Install trouble
I’ve had the Z54 on for a few weeks now and it’s a great improvement over stock. Noticeably longer spool time than the K04 but that was to be expected and does not feel like a slow turbo. Power increase is great in the high rpms and the turbo sounds incredible. For the install, it took quite a bit of time. Having been the first time doing it and having only a general idea of what to expect, it proved to be a bit more difficult than anticipated. Getting off old bolts in tight spaces was not the easiest, but the new turbo went in pretty smoothly with another person helping up top. New gaskets and washers are not included with the turbo but should be replaced to ensure no leaks, so make sure you get those before install. Another note, the Injen hot side charge pipe does NOT work with this turbo and I was not aware prior. I had to order ZZP’s charge pipe to get everything put together. All and all, great turbo and no issues with it at all, but install took a lot longer than expected. Check for coolant line leaks and be sure to not kink your oil return line. Thanks ZZP!

Z54 is AMAZING
All I can say is if you are maxed out on the K04 and want something bigger without breaking the bank this is the turbo for you. Solid turbo. Turbines have been marked so I am assuming they have been properly balanced. Housing and turbines are of high quality, you will not be disappointed. Only issue I had was the coolant plugs developed a leak somehow but I took care of it but other than that I have been running it for 1k miles so far now but she still pulling like a ***** ape. Don't be scared of all the horror reviews. I did my research for years and come to find out that alot of the bad reviews are legit user error.
