Another great episode, you explain the work you are doing excellently. It's a very neat, well thought-out and finely detailed installation as well. I'm looking forward to the next episode.

[@safetythird4555]

Thanks! All episodes of the ECU install are done and posted if you wanted to watch the others.

As an '84 Euro E24 owner this is fascinating but well above my skill level. Looking forward to checking out the 3rd episode!

[@safetythird4555]

Thanks! I'm sure you could do it too. It just takes patience and research.

[@ItsTimePictures]

Way way too technical for me but I watched anyway. Gorgeous car. That engine bay is so damn clean I can’t even believe it!

[@safetythird4555]

Thanks!

Nice attention to detail, this will look fantastic when done. Has to be 3-5 hp & 7-10 ft lbs with the better management and open breathing.
Gee....now its ready for pressurized induction.

[@safetythird4555]

Yeah, that's kinda what I was figuring too. The red plug wires should also give me an additional 15-20 hp!

Thanks for the videos and effort, I was wondering whether it may be easier to completely replace the intake manifold and go to self learning EFI? Also always wondered if a centrifugal supercharger would bolt up but doesn't seem to be the real estate in the front of the engine. Turbos are cool, but the plumbing....

[@safetythird4555]

Like one of those Holley kits for carburetor engines? Yeah, I think that'd work too. But in that case, I think the effort to design and fabricate an intake manifold to interface with one of those would probably be more work than the rewiring here. It'd be interesting to do though.

[@brooke_blank-it]

Yeah the had solex stock manifolds for early 630s that used to be converted to holley, but not sure where you'd find one or if they would fit. www.seniorsix.org/faq/2_4bblconv.html. You are definitely doing it the right way, I'm just inherently lazy 👍
