Let's assume that I have preferences for the comforts of more modern engine technology, but I want to stick to the Lycoming, also for its reliability. I don't necessarily want to stress the engine more. The base performance seems alright. but I hate the prayer ritual when starting engines, the fact that I cannot use Premium (Ethanol) gas (sparing my neighbors the lead coming out of our 100LL), carburator (really?) heat, and other nuisances. [The Rotax 915iS engine is a beauty, but probably not suitable for use in an RV-6 or RV-7. It is also too limited at 141 HP and more expensive than Lycoming, too.]
I have seen various Lycoming enhancements, individually:
* electronic ignition (keep some mags, though!)
* electronic injection
* fuel injection
* exhaust enhancements
* turbo normalizers
* fuel STCs
* does FADEC exist?
Would you recommend some good vendor who shares my general preferences here, and offers an experimental Lycoming with good improvements? Perhaps with extended lifetimes to make up for the extra cost? I did not see enhancements on Vans website. They seem to prefer going stock...as usual. not to blame them. my preferences are half "cosmetic."
If this is too controversial a topic, please email me instead. I do not know if I am stirring up a hornets nest. advice appreciated.
