Yes, something like that.
@Ecky - I'm trying to improve engine's efficiency to lower the fuel consumption with E85 fuel.
My optimist goal would be to have the same or better fuel economy than with gasoline.. even tho it'll be a bit cheating going for a 6spd swap.
I'm quite confident, it won't be as difficult as it may sound like.
Since I have a little bit experience of a high compression engine built just for E85 fuel, and it was a lot more fuel efficient compared to factory condition even without lean burn and "enough" ignition timing while cruising.. and no variable valve timing, plus worse aerodynamics than the BMW E39 plus 500cc bigger engine and even shorter gear ratios (not for street use) which aren't really helping the fuel economy.
Yes, BMW's are expensive to own, atleast if they are not well maintained.
Which is exactly what my (cheap) BMW is.. over 20 invidual faults on it , and I've fixed quite a lot of faults already.
