OK, so heres the engine build so far...
First I accidentally bought this late 1988 325is engine with 1.3 Motronic and all the ancillaries:
Then this M50 328i crank:
Then these 130mm rods:
Stripping engine down (yes, that is an Elan 2 Plus behind me!):
M10 removed and engine bay removed of as much as possible (servos etc)... you can see 40 years of crap in here, also you can see the lower inner wings and bulkhead are still the original Colorado? colour... obviously the car was respra
Update:
Battery install complete for now, The car runs on the one PC680 just fine, amazing such a small battery will happily turn over a six like this but there you go. I installed with an isolation switch through the kick panel:
With that done a I spent a week tuning the carbs as best as I could given the jets I had. I also had to tackle multiple oil leaks and coolant leaks from all the adhoc pipework. It will probably never be 100% leak free particularly with coolant as there are multipl

I installed all the timing gear to test the Piston - Valve clearance, when I installed the piston I found it hit the crank counter weights on the down stroke so I had to file the piston skirts down about 4 mm, all 6 will need doing ultimately, I had read that the Mahl
Hey All,
I am very lazy but thought I might get around to sharing some pics of my winter project so far, it all started when I accidentally bought some M20 mounts and an M50 328i crank. These terrible accidents happen sometimes...
First off, say hello to my '02, Dec '71, one time Colorado, at some point resprayed Inka...
Anyway first thing was first, I needed a diff to take the torque, some say its not necessary, but fabbing my own diff into the 02 seemed a easy way of getting a cheap LSDs
