Thankfully the N54 engine is abundant in the US, I just wish there were more of the 6 and 8 cylinder diesels here.

Install starts tomorrow but I may finish Wednesday since I am a sloth when I wrench.

Hexon RR550 Twins, BMW LL-01 5w-30, Oil Filter, Thermostat, Water Pump, Coolant, Turbo Hardware Kit, Downpipe Gaskets and Hardware, Larger TMAP Sensor.

 

i read in n54tech, tony at vtt charges $1500 for the install. or $125 an hour.

 

I just ordered a set of these turbos, too. How long does it take from ordering to getting these? Also, where did you get the turbo hardware kit and TMAP sensor?

 

Contact Wayne at Hexon and ask about build time. Once mine were assembled shipping only took 4 or 5 days from Taiwan.

You can buy the hardware kit from various places, some kits include different components, I got mine from RB.

The Tmap sensor is an oem part but you will need an adapter sold my BMS.

Thanks for the answers. I just placed an order with RB, BMS, and ECS Tuning to get these parts. I can't wait to get these things installed!

 

Nobody does it for free.

i must have been not clear. i said in case anything goes wrong, like smoking issues, like with some RBs, Tony would not make u pay for labor, over and over.

cant wait for some dynos and time slips when u get those on!

 

Here are some more pics of the turbo install. It was a lot of work but a fun project, I learned a lot.

Sub frame was dropped.


The pile of parts grew!

Hexon vs oem

So much room for activities! All turbo hardware and downpipe hardware were replaced.


In with the new


Checked my valves and it looks like a sleeve on cylinder 4 is bad


Replaced Thermostat and Water Pump, essentially resetting the 80,000 mile time bomb


Replaced passenger side engine mount


Found some wear on the silicone reducer running to my intercooler, I am also happy to report that it wasn't filled with oil.


Decided to refresh the boosted portion of my intake system.


T-bolt clamps are out and my intake system is 100% worm-gear.


All of the silicone humps were cut off the pipes to help improve flow, I did the same thing to my inelt system.

The battle axe that was my prior charge pipe connection


Much better. I will consider it a "good problem" if make enough boost to blow these clamps off! :devil

 

Awesome progress on your car! I have done work on my cars in the past, but I will skip turbo installation and have a local shop do it for me.

I was researching inlet solutions for my car, but after seeing your work, maybe you can fab another set and sell it to me. I'll probably go the VTT inlet route.

Did you replace your front hubs with M5 hubs? I read that was the only way to run those brakes. Big improvement over stock?
