Z3 M Coupé Resto and Engine Rebuild !

[Clubber]

This was an awesome build. Beautiful car.

Thanks my friend.

Then we moved on to the rears, OEM calipers looked worn and the disc base was all rusty, We gave spray black to the calipers and spray silver to disc bases for OEM look,

Here they are before,



After cleanup and paint, much better,





and the next day, my wheel guy called me to check the wheels polished before he mounted the tyres, they looked great







After my approval of the splendid work, they went on the car,









and finally mu lonw awaited injectors arrived as they were the last missing parts for engine start up,



All lined up and installed,





Later on, the transmission will go in and mated to the engine. Then there will be some welding on the exhaust as there is a slight line up problem. Later in the week, we plan to start up the engine with CF airbox and continue with ecu mapping for it. Keep watching !

Make sure you remove the paint from the hub of the brake discs (that the wheel attaches too).
You might have issues with bolts getting unbolted.

Nice rims :thumbs:

I just realized I didn't finish up this thread.. Let me continue ;
Cleaned up some of the heat shields under the trans,



Missing additional fan came and installed,



Wheel bolts looked worn and rusty, so a fresh coat of paint helped,



and finally the radiator was cleaned, you wouldn't believe the amount of dirt came out of that thing. Just take a look to see the difference,



Later on, CF airbox is mounted,



Here is a short video of the first start -up,

S50 rebuild start-up - YouTube

Then we started reassembling some of the new parts like water bottle, radiator heat shields, o2 sensors, additional fan, bits of interior (center console etc.)









airbox in all its glory



Later on, we moved on to closing of the disastrous holes of the hood pins. The holes are filled before paint.
,

With these works, we arrived at the final stage which will include ; adding a cat for comfort ( way too loud now that the turbo is off )
Fine tuning the Alpha N Tuning on the ECU
Painting the hood and bumpers ( due to stone chips and aero stuff mount holes )
Reconditoning the interior and adding a few new touches...

Great job!! What have you been using to clean up all the engine parts? I've always had trouble cleaning up cast ally parts.

Thanks. I usually use alcohol and wd-40 and on some stubborn dirt and grime, some caliper cleaner works like a charm.

[Clubber]

The car was way too loud so installed cats to reduce the noise and it worked like a charm,



Now that most of the engine and mechanical stuff out of the way, we switched back to cosmetic part. The bonnet and bumpers are getting ready for clean-up paint.

Holes from the hood clips filled and primed,





The holes for the hamann aero parts on the rear bumper filled and primed,





Licence plate holes filled and bumper fully primed,



A few days later,

The car got out of paint shop, the paint is flawless and the hood looks 10x better without ricer hood pins. Smooth front bumper without licence plate also adds to the clean look. I am very happy with the results. Before paint shots, we took care of tiny details again

First, I sanded and waxed the headlights as they were really worn and blurry,



Then, I replaced the old looking bumper lights with new ones, old vs new,



On the car,



Finally replaced the number plate light as it was also pretty discolored and dirty,



Old vs. new,



New one put in, much better,



After these little youth touches, she looked much younger





Now that majority of the work is done (engine rebuild, paint, mechanics etc.), it is time for the interior. Tomorrow, I'll drop it to my upholstery guy for a little freshen up and some personal touches We're almost there. Keep watching ...

your attention to detail is admirable, the heat shields look new.

Fantastic work on such a deserving model

BMW certainly lost their way with the models post Z3M

Excellent work Clubber! Your car is looking much much better for all your work, just don't let it get hit by bits of MIG falling out of the sky :clown:

Thanks a lot my friend. Yeah those shields turned out perfect. I also agree that Z3M has better chance of being a future classic than any other following Z car.

TR stands for Turkey.

hahhah thanks. She is safely stored at home. Glad you liked her.

More to come...

Then the car got back from my upholstery guy. He used his usual tricks and skills to liven up the interior. Instead of retrimming in the interior with new leather and such, we went for restoration route.
First, the seats were switched (left to right) so that the entrance bolster were hidden on the other side, then the worn padding got renewed with firm, fresh ones to give extra bit of tight look. Then they were warmed up and weted back to back for a few times. This makes the loose leather stretch back to its original form. Lastly they were washed. Here are the results,

During washing,



Finished look,







Once the rest finished, then came turn for my little personal touches. To keep the black and red theme, I contrast stitched the door grab and center console sides.

Door Grabs,







and the center console sides,







Finally matt painted the airbag, as it was very shiny. Not very clear in this picture but the result is very good.
Overall, I am very happy with interior works. next will be wheel alignment, quick detail.
