FXR Projector Retrofit in P46, in 2004 320i
Good morning folks, I'd like to start off with some background information.
The BMW 320i comes with a halogen setup, with no option from the factory to upgrade to xenon unless you upgrade your entire car. (325, 330 etc) OEM Halogen: http://www.orderkeystone.com/images/400/BM2503112.jpg The owner upgraded to a unit called the Depo Projector46. This unit "looks" wonderful from the outside, but sitting behind the light you'll quickly notice it's poor projector qaulity. TBH, this isn't any better than the halogen setup. The projector outright blows. It does come with AE's, and does look better than halogen units! This is the depo p46 (as it's commonly called): http://www.jlevistreetwerks.com/imag...at%20photo.jpg Here are some comparison shots for the projector vs an OEM projector, in terms of cutoff, spread, hotspots etc: P46 http://img522.imageshack.us/img522/5646/hid001kv1.jpg Another p46 http://img191.imageshack.us/img191/4...gustingp46.jpg OEM http://i303.photobucket.com/albums/n...7/IMG_0449.jpg This now leads me to the projector retrofit! What we're going to do is replace the crappy projector in the depo unit with what's called an FXR projector. This is a replica of the infiniti FX projector, known as one of the best of the best. This is a BIXENON unit, so we'll have to code the car accordingly (for stalk control, example: pull back activates inner halogen, push forward activates BIXENON, as compared to non bixenon setup it would just activate the same inner halogen). The units just arrived today from Mike at F1 Autohaus. This is one of the only places I have found to buy this, not affliated in anyway, just great service and great price.

A picture of the FXR cutoff: http://cdn.shopify.com/s/files/1/003...toff_large.jpg snitz's retro, and here is a gorgeous flicker pic: http://i303.photobucket.com/albums/n...7/DSC_0013.jpg That is all for now, we embark on the journey sooner or later. Thanks for reading this huge ass post! I will update later! Ask any questions, I'll try and help as best I can. Projected HID is the best for driving, hands down! And properly done with GOOD projectors makes it even better. :hitit: |
Here is a writeup by volksfragen, it was done on his car and we did the work together so far:
Hey guys, This is my first DIY/Retrofit Guide. It wont be step by step but it will cover the general way things were done in this retrofit. Id first like to thank Mike from F1Autohaus for hooking myself and Snowcatxx87 up with these FX-R's. They are great Projectors. Quality is superb! F1Autohaus- http://f1autohaus.myshopify.com/ Also a big shout out to Snowcatxx87 for helping and telling me how to do stuff the right way :) First off I am going to start with the products I purchased for this retrofit, then tools needed, then the steps taken so far! Parts Needed For this specific Retrofit, I am using Projector46's as my base Headlamp housing. Projector46's Umnitza: http://umnitza.com/umnitza-projector...on-p-1099.html FX-R Hybrid Projectors F1Autohaus: http://f1autohaus.myshopify.com/prod...rid-projectors E46 Projector Shrouds F1Autohaus: http://f1autohaus.myshopify.com/products/e46-shrouds Tools Needed Various screw drivers Dremel with various attachments Drill with various sized bits Files, Sandpaper, ect. (Anything you think you'll need for cleaning up dremel cuts) JB Weld Available at walmart, Canadian Tire (In Canada :cool), and probably many other hardware stores. Various different screws/bolts I ended up getting 8-32x2.5inch bolts to mount the P46's to the halogen housing and 10x1.5inch metal screws to mount the FX-R's into the P46 mounting holes. Rust-Oleum High Heat Satin Black Rattle Paint I decided to paint everything matte black to go with the theme of my car. This paint said not to use primer, So everything was sanded and cleaned, then painted. To start here is a pic of my workspace: http://i51.photobucket.com/albums/f3...IMG_4129-1.jpg Disassemble Headlight Housing I did not to a write up on how to disassemble the P46's completely, and after some quick searching I could not find one. But honestly If you cant figure it out, I don't think you should be trying this DIY :confused All I can say is take it slow and look at everything and how it works and slowly disassemble everything. Modifications for FX-R Mounting The first part I tackled was modifying the P46 Headlight assembly and FX-R Projector. Shown in the picture below you can see what I had to cut off for the FX-R to fit into the P46 projector housing: http://img690.imageshack.us/img690/6253/95897418.jpg Once that was cut, I had to drill 4 new holes in the FX-R's for them to screw into the P46 projector mounts. In the following pictures the unmodified Projector is on the left, and the one I've modified is on the right. I also had to dremel out some of the lip on the projector so the screw would fit. (Original Mounting holes in white, New ones in red): http://img714.imageshack.us/img714/1559/92314247.jpg http://img693.imageshack.us/img693/2729/14458359.jpg Once the holes were created and everything dremeled out, it mounted flush, and all I had to do was screw it in! http://img97.imageshack.us/img97/2255/82882549.jpg Next was to modify the Shroud ordered from F1Autohaus to fit in the P46 headlight assembly. I basically had to cut off all the chrome flange all the way back to the lipped part, as you can see by the following pictures. the first one is how I purchased them, the second one is after I dremeled most of the shroud off. I also had to cut a flat section off the top so it would fit in the P46 headlight assembly (shown by the red arrow) http://img706.imageshack.us/img706/5509/87138325.jpg http://img529.imageshack.us/img529/7893/18443461.jpg I then went to fit the newly modified shroud, and It would not go in far enough to the assembly to look good over the projector lens. I came to the realization that it was the 4 plastic tabs in the assembly that needed to be trimmed down. I trimmed a bit off so it fit nicely over the projector lens. The first picture is the tabs trimmed and the second one is the shroud and projector test fitted. http://img257.imageshack.us/img257/1458/65338414.jpg http://img412.imageshack.us/img412/5598/36980327.jpg Now that completes the retrofit for the FX-R into the P46 headlight assembly. I was first done here and thought to myself, well I still have another projector, why not use it!? So next I will show you what I did to get the P46, to work in the Halogen (Hi Beam) spot. Mounting The P46 Projector Into Halogen Housing First step for the Hi Beam projector retrofit was to remove the old halogen bulb mount by dremeling it off. I slowly trimmed it down so the projector sat the correct depth in the bowl where I needed it so the shroud would be flush with the top of the bowl: http://img268.imageshack.us/img268/8342/41383664.jpg Next the P46 projector had to be trimmed off in order to fit into the halogen bowl. the red lines are how it looked before trimming. and the white arrows point to the new drilled holes. http://img529.imageshack.us/img529/4109/75900385.jpg In order to secure the P46 Projectors to the Halogen bowl, I set the projector in the bowl exactly where I wanted it, and marked the 4 holes through the new holes drilled in the projector. http://img822.imageshack.us/img822/3811/78708393.jpg In the following pictures, you can see how the P46 projector gets mounted into the bowl. http://img13.imageshack.us/img13/9056/57696990.jpg http://img69.imageshack.us/img69/1369/25649355.jpg I always hated the Depo logo on the P46 projector shroud so **** it, I dremeled it off and sanded it down smooth, and surprise, no more DEPO text :eek: http://img18.imageshack.us/img18/3130/55471136.jpg In this picture you can see how the P46 shroud sits flush with the top of the halogen bowl. http://img94.imageshack.us/img94/7515/39702055.jpg That is all for the P46 Projector in the halogen bowl retrofit. Final Fixup before Paint Now that is basically it for the retrofit. but during the project so far many thing broke. I was surprised at how crappy the P46 headlight assembly was. The plastic had cracked in a few places due to minimal force. I would expect a little more quality out of an after market part... So out came the JB weld to fix the cracks: http://img64.imageshack.us/img64/5795/33505456.jpg Paint Time! Like stated early, this Hi Temp satin black paint asked for no primer. So we sanded all the pieces down, and did 9 very THIN coats to cover it very evenly and they turned out sexy: http://img229.imageshack.us/img229/1812/99565337.jpg Final Test Fit Here are a few pictures of the final test fit before paint. http://i51.photobucket.com/albums/f3...IMG_4128-1.jpg http://i51.photobucket.com/albums/f3...o/IMG_4127.jpg http://i51.photobucket.com/albums/f3...o/IMG_4136.jpg http://i51.photobucket.com/albums/f3...o/IMG_4138.jpg and here's our cars watching us work! (eww my OEM halogens look gross) http://i51.photobucket.com/albums/f3...o/IMG_4144.jpg Thats all for now... This is all I have done so far, I will post updates and such as I get them done. please feel free to ask any questions! Thanks guys! |
Nice, looking forward to reading more. Does your retrofit require the use of any of your P46 parts?

Any other questions just PM me, I am also in the same city as you:rofl: |
Snowcat, I know you've been a strong critic of the P46's. In your opinion, is the FXR version enough of an improvement to overcome your concerns?
Or do you still recommend retrofitting OEM xenons? |
Quote:
I just retrofitted the FXR into my OEM Xenons. The OEM projectores are awfull compared to the FXR's. |
:woot: looking forward to following your progress :thumbsup:

FXR are better than OEM, but my lights are adaptive (they swivel when I turn), which I love and I'd lose that if I did a retro on my car. FXR>OEM>* Quote:

update
|
update with write up!
|
wow nice diy writeup, very clean craftsmanship and install.
|
updates?
|
What do you think the end cost will be? Can you retain bixenon functionality? I'd love to increase my lighting even more (although w/ the bixenons+halogen highs, my current setup is probably the brightest I've seen so far)
|
End cost is looking at around 180 CANADIAN.
The FXR is a great projector. I have pictures to upload tonight, had a busy weekend and didn't get around to it. (hiking trips) We're enabling all the lights as well, and man, this is mega bright. Firstly the cutoff is cleaner than OEM, but the inner xenon with a removed cutoff is just insane. Pics will be uploaded in 8 or so hours! |
MUCH Needed passenger update!
|
nice, its looking awesome so far!! dude i wish you wouldn't have done the quad....cause i have my old p46 projectors and my old e46 bixenon projectors laying around doing nothing, and its giving me ideas :idea::4ngie:......how sick would it be to have quad bi-xenons....lows, highs, extra highs, ÜBER HIGHS :excited:!!!
|
The guy was like, I want OEM lights P46 blow - I said wait, lets try a retro. He said ok. On the way here I said, lets move the p46 to the inner and it just kept on going LOL!
Quads are awesome, and it LOOKs awesome. You def have the parts so do it up man! I'm glad I convinced him to push the inner projector forward more, to sit flush with the bowl, it makes it look better than being sunken in. The other side is DONE and awaiting bumper modifications before it all goes backtogether. |

Would that "additional xenon retrofit" option under SSS allow me to use HIDs w/ the inner bulbs without having flickering issues? |
^ Not sure if they ever had a HID option for the inner from factory? Doubt it. We don't get flickering problems on the inner...
