Z3 M Coupé Resto and Engine Rebuild !

[Clubber]

Hey everyone,

In the brief time I spent on this site, I realized that most of you are not only CSL fans but also general ///M car lovers, just like me. So I thought I could share my little restoration projects of my other ///M cars for others to hopefully enjoy.

This is the restoration of my '00 M Coupé which I acquired almost two years ago ;

The car was turbo'ed by the PO which I admit was part of the charm for me although I am a die hard NA man. I just wanted something different then my old Dakar Yellow M Coupé (Gone). But after a few months of ownership the novelty of Turbo setup wore off and I missed the driving characteristics of a strong NA engine.
So , I have started work on reversing the car to NA and doing other bits and mods along the way.

I had a similar thread for my Dakar MC last year which was fun to create, here it is,

Dakar MC Restoration From Turkey

I know many of us like these build threads so I decided create another one for the new ride.

Here is a list of things we did first,

-Turbo Kit taken out
-Extra Gauges and control units (EVC,AFR DEFI etc.) taken out
-Engine Cover stripped of cheesy paint theme
-All the fluids replaced (TWS for Engine, FM Booster for Diff, SRT for brakes and OEM Trans Fluid)
-Alu look door trim installed ( To match the exterior color )
-New Floor mats put and leather bordered
-Custom Pedal Set designed and installed
-Engine taken out for NA rebuild and stripped of boy racer paint
-Hamann Roof wing replaced with ACS piece.
-Replaced painted grills with OEM chrome parts.
-OEM Short Roof Antenna put in.

What is next ?

-Full NA engine rebuild
-CF Airbox
-Repainting every engine part to stock colors
-Polishing stock headers before install
-Removing Hamann Side Skirts and maybe rear side diffusers ?
-Leather reconditioning of the interior
-Adding red stitching to door grabs and center console L pieces
-Replacing aftermarket headunit and cd changer with OEM parts
-ECU tune to run the airbox
-Replacing worn BBS center caps with new ones.
-Major detailing including underbody to finish everything off.

and as always taking care of little surprises and hiccups along the way

So, lets begin,

This is her, aka " Junior " the day I bought her with po's plates,



First things first, we replaced all fluids, (TWS for Engine, FM Booster for Diff, SRT for brakes and OEM Trans Fluid)
Old Diff oil. This so called lifetime oil was literally black,





New OEM Diff Oil with FM Booster put in ($$$$!)



Before moving in to engine rebuild, I made some cosmetic enhancements,
Replaced the black door trims with alu look trim to give a little contrast to the cabin and reflect the exterior color.

Then got some new floor mats and leather bordered them in red to highlight them a bit, ( You can almost see the boy racer gauges on center console )





Then replaced the Hamann pedal set with custom pedals made specifcly for my car by www.bmwpedals.com

Last thing for the interior was to remove the turbo control units and replacing the ashtray,
