Power goals/expectations

Looking for some input. Got a 135i pretty cheap and its a blast to drive. Decided to throw a bunch of money at it in hopes to make 450-500 whp. Subframe is coming off so now is the time to do any maintenance. I have the following parts on order. If im missing something let me know.

- Pure600 turbos

- 2" inlet relocation kit ARM

- Hi-flow outlets ARM

- CL DP ARM

- 7" intercooler ARM

- Upgrades IC hoses and new orings/gaskets

- Aluminum charge pipe and HKS BOV

- bilstien b14 coilovers

- NGK 97506 Colder plugs

- few other maintenance parts (oil pan gasket, motor mounts)

I still need to figure out a tune. I am thinking MHD stage 2+. Seems convenient and reliable. However is 450-500 hp possible on this tune? At what point do i reach the fuel system limits? This technically my wifes car so i am not trying to make things too complicated with e85.

Headlight not working. Next step?

Looking for advice. My passanger low/high beam on a 2009 135i wont turn on. At first i thought it was a FRM issue but everything else is working (for the most part). In the video i use my foxwell scanner to activate the light and it turns on for the 15 sec and it looks like it wants to clear the code. So i know the headlight works and can get power.

What i have tried

- new headlight

- cleaning FRM connectors (looked clean but cleaned anyway)

- clearing FRM faults

- swapping headlights(passanger side still didnt work)

- checked all fuses (fine)

Next to try

- some how inspect the whole wire harness

- pull fuse box and inspect the back for corrosion

- send FRM out for a reflash. Cant hurt. Recommendations welcome.

- maybe a headlight switch?

- accept defeat by the germans and sell it.

Other things to note.

- One of the tabs on the headlight connector is broken (if anyone knows where i can get one, that would be great)

- My horn doesnt work

- Key fob buttons dont work.

- rear brake light alarms even though they work fine.

Later Year C3 LS Swap

Looking for opinions on which years would be best for a LS swap. Looking to make a street car with around 400-500hp with a LS2 and maybe a little Nitrous. I like the look of the hatchback but dont really know what changed between the later years? 82' had the 700r4 which is nice but they tend to be pricier, i can get a 4L80e for the cost difference. Did chassis electronics change over the years? Suspension? Frame/stiffness?
