Hello Decoupe,
The bellows was included with a steering wheel hub extension. It is an aftermarket part for sure. I believe I got both the extension and the bellows from Momo, but that was back in 2002- I don't believe I have the reciept for it to tell you where it came from. I used a Momo Prototipo wheel Try their website to see what they have.
I've been looking for the bellows type transition between the steering wheel and steering column housing on your coupe - what is it from? Can't find it through Realoem.com.
The banjo bolts were taken /cut from the original PS hoses. I silver- soldered some brass barbed fittings in each banjo bolt in order to be able to install simple rubber hoses (3/8" IIRC) over the barbed fittings, retained with a hose clamp.
As far as the steering load, it is very manageable at anything other than stopped. The steering is still pretty slow in terms of the ratio, but I find it to give a good "feel".
I am not runnig a wide-band O2 sensor. I am running an older Autometer AFR gauge, whihc gives more aof ageneral indication as opposed to a real AFR number. The leaded race gas "poisons" the o2 sensor over time , but you can clean it with a torch- or so I understand. That gauge has been very helpful in sorting out a lean stumble and misfire early in the tuning. If I had it to do over, I would have bought the wide-band unit, but I guess it is close to $400USD. However $400 is Cheaper than a burned piston, though... I will check out the site and your reccomendation- Thanks for posting that link!!
My biggest issue with the motor is the fule delivery system. The motor is running out of fuel volume at high demands (Wide Open Throttle) WOT for an extended pull of say 15 seconds or more will cause me to run lean. Fuel delivery is marginal, and I must fix that before going to the track. low fuel delivery is Very dangerous to the well-being of your motor.... Consequently, I am going with a larger regulator, and will re-assess the fuel pump since the original pump I installed went "belly up" last night (see the earler post by me.
The banjo bolts you used to convert the PS box to manual - are they a BMW part (doubt it)? Did you have to have them fabricated? Subjectively, at what speed does this stop feeling like arm wrestling and more like driving? On my 320i, it doesn't take more than barely moving. Thought I'd try this before hunting for a manual box.
Thanks for your compliments!

Lastly, have you installed a wide band o2 meter to help set up the jetting. I changed over to a WMS (
www.wmswideband.com/ ) and it has been a huge help - very precise. No affiliation but definitely a recommendation.
Great car, thanks for sharing your ideas.
