uDwa4_SYmFc Upgraded my fuel pump in my turbo Z4 to a DeatschWerks DW200 last year, and made an impromptu video about the process of replacing the fuel pump assembly and fuel filter/fuel pressure regulator assembly. Photos of my aftermarket fuel pump installed in the factory pump housing...

With a horribly-slipping clutch, the car put down 300whp, and 275 ft/lbs on a dynojet 248C. Those specs are at the wheels (So like 358hp and 324 ft/lbs or so?) with a rubbing, slipping clutch. I didn't give the clutch enough break-in time and I don't think the pressure plate has enough clamping...

Thank you :D Updated the original post. Much appreciated :)

Youtube link added to original post. Didn't embed for whatever reason. :|

I'm gonna have to either run it without the plate or make cuts/notches and possibly reweld the plate to fit around some things.

I'm gonna aim for 350whp to start and work my way up from there :D It's running on a factory E46 3 series ECU (Siemens MS43) tuned by me, with a modified engine harness from an E46 3 series . Had to add the coolant outlet temperature sensor wiring and ac compressor trigger wiring, as those are...

If you don't know what MS43 is: https://www.ms4x.net/index.php?title=Siemens_MS43 It's the ECU that came in M54-powered E39 5-series, E53 X5s, Z3s, and most M54 E46 3-series models. Some E46 models had the MS45.1 ECU. Converting your Z4 to this ECU will make it much easier to tune the car for...

This is all a direct swap into M54-powered cars. For N52 cars (3.0si), you may be able to use a LUK LF30 power steering pump from an E90 with an E36/E46 steering rack and ATF fluid. The LUK LF30 was used in some early E46s with ATF, and in E9X models with CHF11S. Parts you will need: Steering...

My interior is really coming together. A little dirty though. Need new shift boots and to rewrap the steering wheel in perforated leather.

The E85 Z4 and E46 3-series convertible have the FZV antenna amplifier (remote locking amplifier) built into the rearview mirror. Circled in green. This piece can't be bought on its own. If its faulty, your best bet is a used E46 convertible mirror, replacement mirror of the original, or...

110k miles. Interior was pretty trashed, for the (to-me) relatively low miles, in part because of the car being a sun-baked Florida car. I swapped it from beige to black, carpet and all, with E46 3-series sports seats, and redid the center console in Alcantara, with the dash trims in Alcantara...

The silver that the gauge cluster bezels, AC vents, radio, window switches, and center console insert trims on 2003-2005 E85s are painted is called Titan Shadow by BMW. This color was also used in the E46 M3 interior, for the SMG shifter surround, SMG paddles, steering wheel trim, and as an...
