ECU Replacement??

Don't forget that the engine controls including the electronic throttle control do swap signals both ways with the rest of the car.

Integration to get the rest to work again and together with the new bits will probably be more work than the engine control conversion

My personal feelings that the problems the Ancient systems will generate over time may be less than the problems generated in conversion.

But then I know people that thrive on challenges like this. Would you be doing all of the integration yourself? Or paying someone for all or part of the labor?

These folks were doing a distributorless conversion on their modified M70.
You may want to contact them. But it looks like they chip the original system now (parts list includes 2 chips)

And G-Power may be doing something also http://www.g-power.de/740.html?&L=1

But it reads as if they are just writing chips now also.

It seems G-power is capable of transplanting a 550 bhp V10 from the m5 into the 8 Sweet.

Almost anything is possible with enough money

Given the motors in the 8 arent that hot for v8's I have always toyed with the idea of a 340c.i. Mopar engine to spice things up and get some real horse power, I had a Challenger that would run 12.80 quarter mile times, the engine was same weight as 840 but put out 450 hp, plenty of room in engine bay.

Its on;y the looks that attract me to 8's the motors are not that hot considering the complexity. I.M.H.O

My favorite thought was replacing a bad Nicasil V8 with a LS-whatever GM engine and transmission. Real cheap horsepower up to about 600 there

Of course I would have to do black and silver engine covers with BMW markings on them just for the confusion factor

All your problems are solved if you install an M62 and a Vortec blower.

400 Hp with no dizzy, no plug leads and quad cams that can rev their ring out without a spanner or modification.

Which came first Terry? the M60 or the Ford modular or was it the same design team on CRACK?

For those of you not yet convinced check the archives on Steve's car

I suppose that it comes down to what you start with and where you want to end up Unfortunately that requires planning and $$$

Here in the US it would cost about $7000 to supercharge to 400 hp and $5000+ to convert to a 6 speed on an 840.

For probably much less than $10,000 I could have about 500 to 600 hp and a 5 or 6 speed manual using an aluminum American GM V8.

Now bear in mind that I have no intention of carving my Little Silver Mistress up to do this It would have to be another 840 with the dreaded Nicasil problem.

The first design goal would be to make it reversible by using adapters rather than cutting out chunks to make room--No Dinan Z8's here

Nightmares every night for months interfacing the Electrics of course but Plug and Play with a kit for sale at the end of course.

At this point it is Dream and not Nightmare and it will probably stay that way for a while.
