A beautiful example of a E38 M Sport 740i, but can it dance?
I've had my gorgeous 2001 M Sport 740i for 3 yrs. I replaced the suspension front and rear, installed Bilstein B6 shocks, had the engine running perfect, new brakes, and everything was fine. Then I made the mistake of taking out to Autocross twice. I can't resist building race cars, and who races and tracks a 740? nobody does, so I'm in.
They never intended this when they designed it for comfort
The automatic shifts nice, but it will break. Too much body movement also.
Car went into my garage November 1st. I stripped the engine down to the long block, cleaned everything and started by pulling the timing chains and guides. These V8's are great motors with a timing chain system that requires replacing at some point around 150k miles, and a crankcase vent system that needs replacing around the same time. My car has 138k on it, so to be safe everything gets replaced.
Chains and guides still in good shape, but you don't go this far without doing them
Setting VANOS timing with new chains and guides.
Every component gets replaced as it goes back together. If its not new, it gets scrubbed, sanded and freshly painted.
Here's where it sits now. I need access to the upper transmission bolts to pull the trans... why? I'm converting it to a 6-speed manual. The automatic shifts great, nice and quick in sport mode, but it will never stand up to road course sessions. Also the manual is some 250lbs lighter than the auto.
What about that body roll?
I did not like my options for springs, so I've gone ISC coilovers with track/race valving. A 15mm rear bar will be retrofitted since the 740i never had a rear. Front bar is a hefty 24mm. I'm using the big brakes from the 750iL. The caliper is dual 42mm pistons instead of one, 32mm larger rotor and about 30% more swept area. Should get the job done.
