the reason why im asking is because the weight seems to be pretty low ,but anyway i was also wanted more info about o-235 lycoming but all the o-235 are low compression engines the max i can get is 116 hp from o-235 n2c which i have on hand just need top overhaul ,i dont know if i can put cylinders from high compression engine like k2 or similar which i can by from eci on it ,but the question here is do i get any more hp ,do i hurt the engine or tbo i dont know ,i dont want use any o-320 because they weight a lot and eat gas like crazy thanks
