Guess I need to start shopping for a rear- ended 2010 528i, huh?

Yeah, I must be getting old, but what excites me about this project is
programming the 8HP to do what I want it to do....

I kinda expect to add a bit more coolant after the system's been open.
It seems like air can hide just about anywheres in there, and only time
lets it fully burp out.

Which...

I bought a 'proper' hone many moons ago. A Lisle 15000, I think.
If you are athletic and use a slow- turning drill AND an automatic luber of some
kind, it will give a pretty good finish,...

Oh, Christ on a Capon, slide throttles are
another can of friction- filled rules- skirting nightmares! ;)
Just use 41mm throttle plates!

But seriously, air box design is not...

A bigger evaporator is probably a f---ton easier than a 3kw alternator and 2-0
wires running to the electric compressor...

Power is power. Running a compressor off the belt drive...

Isn't there a starter motor issue, too?

An E46er who adapted an 8hp had a whole saga of having to
get the bellhousing welded to hang the starter for the M5x engine...

no help here- I just braze AN fittings onto the old hose ends and use -10 line...

The fast PRO3 engine builder around here straightens
all their cranks before they even start- so there might be
something to the length of an M20 contributing to its... droop?

Well, I have nothing but respect for someone who's willing to dive into the deep end
upon first seeing a swimming pool!

My 02 (we have 2 of them) is not to be too ready to CNC everything-...

There's a metal y pipe up in there close to the filler that likes to rust away, and then if the tank's pretty full it will leak.

It's worth pulling the right rear wheel and then the plastic...

be careful what you wish for... we're not all that eloquent, here...

Put a fuel pressure gauge on it, and see if it loses pressure when you switch it off.

Likewise, when it's starting hard, floor it and crank it until it catches.

What we're looking...

I built M10 race motors on a stand, hanging them off the side of the block. That seemed to work ok,
and was easier for assembling the rear seal, doing flywheel and transmission alignment and so...

First, have you cleaned the larger bore? This is a classic symptom of carbon buildup inside there.

Second, as Jordan asks, have you checked for bushing play? It's unusual for the secondary...

Since they're tty bolts, you could give them all another 30 degrees
(in the correct sequence) and it wouldn't hurt anything.

But I'd be surprised if it helped...

Oil pressure isn't hard- just pull the signal from the switch where it enters the DME.

The alternator is a stinker, because it communicates BSD to the DME,
and that's how they do all...

IF the E34 radiator is like the E39, it's too big to fit. The 5er is a wider car...

As to the air conditioning, shops can make hoses with whichever ends you want,
so it's usually just...

You have an 8 liter reserve capacity,
dating back to when fuel gauges were only found on very fansy
cars, and the rest of us got a second 'reserve' tank to get home on...

If the spark at the plug looks healthy and you're not getting misfires at WOT, I would wait for
the injectors to get back... coils very rarely fail, and when they do, it's often something annoying...
