You're very right, I'm a purist
my biggest sin is using those beautifull BBS RS1 15" rims on my Murena, but I have original repainted wheels with new Bridgestones for meetings
I understand Your motive, but if You're going to invest Your time, effort and money, wouldn't it be for something more "efectivelly"? I mean - one friend of mine is working as a design engineer for VW group, Mercedes-Benz, etc. He will never buy a new car because he knows how much they are ripped off because of costs reductions everywhere (for ex. they are welding the chassis as short time as possible with as small voltage as is enough for NCAP tests, metal sheets are thiner and thiner and everything is done for minimise the production costs... but that's Off Topic). He owns a lot of older cars, also one Murena 2,2 which is under "reconstruction" - possibilities of my friend are very wide so he decided to improove that old 2,2 Chrysler-Simca engine. Used forged pistons, lightened piston rods, special bearings, exhaust is calculated exactly with camshaft and bigger carburetors, stiffers valve springs, etc. He spent cca 6000,- Eur and reached 230PS at 7400 rpm (if I remember good). But from outside, the engine will still look as the original
I saw a lot of modifications of Murena, some of them really far away from Murenas idea (those Honda, Mazda, Ford, etc. engines), some acceptable for me (Peugeot 505 Turbo - what in fact is an evolution of our 2,2 engine, 1,9 GTI or Mi16 - as evolution of 1,6 Murena), some of them done very cleanly, some of them are stupidly difficult and "piggy" (if it has the right sense in English language
), but realy think that there have to be some "plus" at the end suitable to Your effort.
And to Your question
I really don't believe to all these theories. Look how long we had to spend money for ecobusiness in the name of CO2 and heating of the Earth. All emision fees, taxes and restrictions, and now scientists found that CO2 aren't too much wrong and also that in fact we are going to face small Ice age. I think that there are some cycles in weather and human effect is irrelevant, or I have to say - personal car traffic, which is most taxed, has the minimal influence on it. One big ship engine produces in 1 hour same ammount of CO2 as one car in 5 years, and I have read that the biggest 10 transatlantic ships are producing more emisions than all cars all over the world. Than count airplanes, factories in China with no filters and controls, and many more. And Europoliticians will say that we have to pay, that our car produces more CO2 than new one? Do I have to believe them? It's only (eco)business, like it was for all times in history, people are still the same, so I don't think that we will be alive when there will be only electromobiles
Oil gigants will do everything to keep us dependent on them and I don't believe to politicians that there is not enaugh of oil. And at the worst, I could make a covered GPL modification
PS: but back to Murena - if You want I can find a contact to one firm in Belgium, where You'll send Your 2,2 cam + 220,-E and they will send You the 2,2 S cam - I did the same.
