Are you planning to run it on ethanol or any other alternate fuel? BTW about some 15 years ago Volkswagen and Bosch performed some tests with a port-injection engine fitted with turbo, and it was tuned to have 3 different boost stages to alternate between gasoline, ethanol and CNG.

well, my lada had a non-crossflow, swirl-type combustion chamber (for better starting, even atomization and burning of even crappier fuel, but it raises piston temperature on higher revs so it gave really noticeable good results in the rain)

That might've been essential to withstand to the Russian winter, but would either demand an excessive enrichment of the mixture in warmer weather or a higher capacity cooling system. Well, since some moisture in the intake flow decreases the likelihood of knocks and pre-ignition, it's no surprise the engine would become more efficient under those conditions.

Ethanol, or rather E85 has been planned.

RE85 is 85% finnish food waste ethanol, 25% imported gasoline. not quite great as in Brazil, but our colder weather would prove neigh impossible for E100

broke 40MPG! it seems the RVS ceramic treatment has broken in on the metal surfaces and lessened friction.

after this, I removed the intake resonator, got more low-end torque. We'll see if the mileage goes down or up when the engine takes hotter air from behind the engine

40 isn't terrible considering you were pushing it pretty hard on the highway, from what I recall.

Well, i drive 18 miles/30km to the job, going 60mph/100kmh

Oh - I see your fuel log. You've done more fill-ups! I was thinking of the 700 km trip with some 70 mph / 112 km/h roads.

When I mentioned ethanol, I was already considering the easier availability of E85 there in Finland, even though the colder weather could eventually not become impossible to use E100. Well, some cold-start aid would be required anyway (unless you were switching to direct injection which I don't believe you'd be likely to do).

ugh, the rear brake drums are very rusted- must swap for both inspection and personal safety

Also found some rust holes, euugghh. Good thing i know how to weld. Im just gonna cut all even remotely rusted metal away properly, will be a more long-term solution. Might as well keep a car for once (i still own the volvo but my friend is driving it)

Share some photos of these rusty drums, when you get a chance...I've yet to see ones with more than just surface rust.

broke 50 mpg!

holy moly, don't know how but i guess it's the highway drivn'
