E28 Alpina Build - by Pedi

9 minute(s) of a 417 minute read

The day before I went offshore, I finally found my problem. It was a Alpina-installed powercable that "lost" power when I turned the engine. Gave the cable permanent B+, and things happened!!

Check the vid (sorry bad quality, I was in a hurry - and just used my Iphone):




When I return back home, my first thing to do is exhaust, cooling system, change the starter (works periodically) and other engine-related stuff. Hopefully I will have the time to adjust the remaining chassis parts: front wings and hood. Make it ready for the spray booth... I really wish to have this car ready for summer action - it all depends on sparetime from work and the (already empty) wallet

anyway, thank you for visiting my thread again!

Hello guys, just a little update here...




Love this one!

Had to change startermotor, so first of all - I had to cut an old 17mm spanner



For more easy access:



I went for a M70-starter, it is 2.2kW compared to the original 1,5kW M30-starter.



Finally, it was time to mount coolant tank etc...




My original TurboKat exhaust is in bad shape from Kat and back. So I will first of all weld onto a 535i-mid and rear exhaust - just to have an exhaust that works. I will make a custom on later...








Drilled 19mm hole for the AFR-sensor














Welded, ready for action...






Mounted the exhaust bandage the wrong direction first... :stupid: :stupid:






And off, to install it the correct way...







Finally:







Looks better now.







Not much clearance, glad that I have the bandage......










Here is the flexi for the DP, not quite fancy - but does the work.







New gaskets:







Wastegate, ready for action as well







I guess I need one like this?







Ohhh... Tight fit...







Better?







Alpina heat covers







As the exhaust is on, time for radiator!!






Here is the difference between the original and Alpina. Dirty Alpina hose??






Some cleaning does the thing







Ready for start-up. With ignition on, I discovered that the engine was at a temp of 21 degrees celcius. Nice temp in garage at winter??







It is lovely to finally use the exhaust-extraction!!







Start-up!!






A small video. No LMM installed, no vacuumhoses etc. Just wanted to hear the sound of the engine with exhaust...





Got the part machined for the turbo-inlet:




backwards....





Installed/glued in position.






Looks good, perfect fit.



Leaks from the cover, damn...






Found one, just need some care..






Needed to shine the covers too.






Looks better now.






I should have sandblasted the cover. Too much paint....






First layer, primer:







All pressure-pipes got a silver color







New parts are good








Turned out nice, those covers.







Made some mods to the front panel, due to tight fit.







Good to go!.







Another angle:







The dump valve has not been mounted by me. The guys did this missed totally. I will fix this.






Vacuumhoses in position, both O2-sensors installed.








I have just ordered new spark plugs, Bosch W6DPO. Was $60 each !!!!!


I have too low oil pressure, 0.6 bar@idle (warm) and 1.8 bar @ higher RPM..

Guess I have to take down the oil pan tonight, and dismantle the oil pump....


So this is how it looks like as of today!

Good night, gentlemen!
