Before the project can truly begin, the BMW is washed thoroughly. In our german Christ carwash, that is equpped with foam brushes that doesn't scratch the paitnjob to begin with. Thereafter rims, engine and more gets washed with a high-pressure water hose.
These preparations make the upcoming installations go more seamless, smooth and easy.

Vi had a used Schmiedmann Big Brake kit in stock, that we chose to install in the front.
The brakediscs of the Schmiedmann big brake kit was about 3 mm smaller in diameter and 2mm slimmer than the standard BMW 335I brake kit. The standard kits has the dimensions: 348x30 as opposed to the Schmiedmann big brake kit's 345x28mm.
On the other hand, the brake discs of the Schmiedmann big brake kit has a floating suspension with aluminium hub (from a BMW E46 M3 CSL) and holes for extra ventilation. Also, the big brake kit has 6 pistoned Schmiedmann/Brembo calipers, so we chose to install the kit despite the slighty smaller dimension of the brake discs.
An extra benefit of installing this kit is, that it looks marvelous.
Original BMW "sharkfin" antenna dummy.
The shark fin is originally designed to be nailed to the roof with screws.
However we choose to install the sharkfin with double-adhesive tape.
The "legs" for the screws are cut off.
Before the sharkfin is installed, the area where it is to be fitted has to be cleaned thoroughly. We de-grease the area with brake cleaner, product number:61100914
If the area is cleaned properly, the tape will stick better.
The sharkfin is installed 60 mm from the rear window.
In order to mark the area of installation, we use masking tape.
The foliage is taken off the double adhesive tape.
Now the sharkfin is installed.
Now the time has come to install the 19" Z-Performance -Type 9- alloy wheels.

Update - February 2016
I de seneste par uger har vi igen løbende arbejdet på vores BMW E90 335I projektbil, som vi også tidligere har vist billeder af. Her får du et sammendrag af nogle af de modificeringer vi har lavet denne gang. Denne gang monterer vores teknikere Schmiedmann signature stage II turboladere, Schmiedmann by Supersprint komplet udstødningssystem, samt nye indsprøjtningsdyser.
The pas couple of weeks, we have been working on our BMW E90 335I project car again. Here you'll get a recap of some of the modificiations that we've made thise time.
In short, this time our technicias will install:
Schmiedmann signature stage II turbo chargers
Schmiedmann by Supersprint full exhaust system
New injection nozzles
Replacement of injection nozzles:
Here you see the old BMW injection nozzles.
The old injection nozzles are screwn out of the cylinderhead.
The injection nozzles are removed from
the cylinder head.
Here you see the injection nozzles uninstalled.
The new injection nozzles are being installed.
The injection nozzles are a weak link for BMW's with a high-pressure fuelling system. They get worn out, which leads to an irregular engine rythm - on this BMW E90 335I, it was especially noticable when the car was idling. As the engine will perform more wtih the new turbochargers, we thought that this would be the perfect time to replace the injection nozzles, even though the error wasn't fatal yet.
We uninstalled the intake manifold, too, and blew the intake ports and valve tighteners free of soot with our original BMW cleaning system.
The cleaning will give a more even engine rhythm, a better gas mileage as well as better performance.
This procedure is reccommended to anyone who has a BMW with a high-pressure fueling system, don't hesitate to contact us for non-comittal offer.
Even though this BMW E90 335I hasn't driven many kilometres yet (130.000km), the intake is already quite sooted because of the AGR/EGR system, that leads the exhaust through the intake in order to reduce pollution.
In order to clean the intake, BMW has invented a small cleaning devide, that under high pressure uses walnut granulate to clean the soot off the valve stems and intake ports in the cylinder head.
Installation of Schmiedmann signature stage II turbochargers
The N54 signature stage II upgrade turbo modification consists of the following:
Upgraded 15T CNC manufactured compressor wheel 42/60 mm.
Upgraded TD4 turbine shaft 41/47 mm.
Turbine housing modified for TD4.
Upgraded wastegate bushing (get rid of wastegate rattle)
Upgraded bearing type (race)
Step gab rings on both sides of the shaft
Balanced in a VSR machine at 180.000 rpm.
100% OEM installation, plug & play.
Can deliver an effect of up to 550Hp with a high torque

Update - April 2017
1st Dyno run
Finally, the day that we'd been waiting for came. The day when we'd get exact numbers on the performance of our BMW e90 LCI -S3- 335I. See, how the dyno run went, in video below:
Result: 446,3Hp / 511Nm
- A result that we're quite satisfied with. Especially considering that the BMW M3 "only" has 431Hp. So our goal of beating the M3 has been met!
The clutch slipped a bit, though. And so therefore we chose to install a new Sachs sport clutch, so that we can transmit the full performance of the N54-engine to the dyno.
Apart from that, we could tell from some of the tests and logs, we've run on the car, that the original fuel pump is not capable of delivering a sufficient amount of fuel for the engine. Therefore, we will also be upgrading the fuel pump to stage II.
Update - May 2017 Installation of Sachs Engineering sport clutch
See in the video above, how we install a Sachs Engineering sport clutch. The clutch is organic, so the car can still be used for daily driving, though the new clutch is somewhat harder to push than the original BMW clutch.
Upgrade/modification of the fuel pump for stage II
In order to be able to provide a sufficient quantity of fuel, that a tuned engine like ours, we also had to upgrade the fuel pump to stage II. See in the video above how the modification went.

We also have a few pictures of from the evening:
Update 1 - October 2017
